Which are the Different Architectures for Multimedia-based Applications?
There are various architectures in multimedia applications.
Here is an overview of the common architectures used in Multimedia-based applications.
Multimedia IC Chip
· Function-Oriented Architectures
A function-specific architecture involves a direct mapping of the processing tasks of the
multimedia to hardware implementation developed to perform specific tasks.
The pairing of the independent hardware components to the processing requirements lead to area efficient executions.
Speed and efficiency are usually better than those given by programmable architectures.
The typical design of these types of multimedia IC processor comprises applying a RISC processor for the central processing unit.
For distinct multimedia algorithms, it uses special hardware accelerators such as:
- Motion estimation
- Entropy encoding
- Discrete Cosine Transform (DCT)
· Programmable Architectures
Programmable architectures used in multimedia chips can be classified into:
- Flexible programmable architectures that offer moderate to high versatility, and
- Adapted programmable architectures that offer less versatility but higher efficiency.
Designing of programmable architectures apply various approaches like Instruction Level Parallelism (ILP), Data Level Parallelism (DLP) and TLP.
Alternatively, it can adapt to special algorithm features by implementing dedicated hardware modules and specialized commands.
These lead to higher efficiency for a restricted application field.
· Adapted Programmable Architectures (APAs)
APAs offers enhanced efficiency by attuning the architecture to the distinct needs of the video coding applications.
The architectures offer dedicated modules for various functions of the video codec algorithm like Variable length Coding (VLC), or DCT module.
· Very Long Instruction Word Architectures
A VLIW processor consists of several independent function devices and performs multiple tasks in parallel.
These tasks are put in a very long instruction word.
It is the responsibility of the compiler to locate independent instructions that can be categorized in a VLIW.
Processors of these types of architectures can attain high performance by applying DLP and ILP.
What is the Difference between Asymmetric Compression and Symmetric Compression in Multimedia Systems?
In symmetric compression, the system is modeled to require approximately equivalent computational potential from both the sender and recipient.
Videoconferencing is an ideal example of this context, in which every terminal must both relay and receive.
On the other hand, Asymmetric compression puts more emphasis on encoding to make the decoder simpler.
A perfect example of an asymmetric compression system is broadcast systems, where a sophisticated transmitter relays content to multiple simpler receivers.
What is the Importance of Codec in Multimedia IC?
Ultra-low voice codec
Compression-decompression or coder-decoder, normally, abbreviated as Codec, is a standard employed for coding and decoding digital media, particularly audio and video.
These two forms of digital media have traditionally used up considerable bandwidth.
Generally, codecs are utilized to transfer media (either as a stream of discrete files) across computer networks or store data on disk.
By swiftly compressing and decompressing the files or data, codec reduces the needed bandwidth.
This leads to increased interaction and access and transfer of multimedia content across networks.
Codecs are of great significance to multimedia applications’ success on the internet, spanning from teleconferencing to webcasting.
A codec can be either a hardware device or a computer program, which has the capacity to store data on digital devices and transmit large media content across network or internet.
It facilitates this by lowering the overall needed bandwidth.
Codecs apply a mathematical algorithm that converts and condenses the data for relaying.
The primary objective of developing and applying codecs is to facilitate the playing of media files on gadgets apart from the one it was intended.
As earlier stated, there are two essential roles of codecs in multimedia ICs.
They help in transforming data or files from analog to digital and from digital to analog formats.
Secondly, codecs are instrumental in the encoding process of video and audio recorded by a video camera or microphone to a digital format.
This enables its transmission to the receiver through streaming, broadcasting or videoconferencing.
Presently, there are several codecs with their respective advantages and offer support for distinct functions.
For example, in case you want to upload a video file to a website, you will need a different codec from the one you would employ to play the video directly from your video media player.
Is there a difference between Multimedia IC and Multimedia Chip?
No, a multimedia integrated circuit is at times referred to as a multimedia chip or multimedia microchip.
The terms can be applied interchangeably to refer to semiconductor wafers.
Where, microprocessors, memories, transistors, capacitors and resistors among other components are fabricated to enable the operation of multimedia systems.
What is SDRAM and DRAM in a multimedia IC?
The memories are synchronized with the microprocessor’s clock speed, which tends to multiply the number of commands the processor can execute within a specific time.
SDRAM speed is rated in MHz instead of nanoseconds (ns). This enables easy comparison of the speed of the RAM chip and that of the bus.
Dynamic random-access memory (DRAM) is a kind of random access memory that stores every bandwidth of data inside a memory cell comprising of a tiny transistor and capacitor.
Both the capacitor and transistor typically apply metal-oxide-semiconductor (MOS) technology.
DRAM is a RAM type that retains its content provided you refresh the data stored in the gadget at regular intervals.
DRAM needs to be refreshed after every millisecond to maintain its data. The capacitor, which stores the data, slowly leaks therefore, the regular refreshing helps in recharging it.
DRAM is less costly than SRAM, nevertheless, DRAM is much slower due to the prolonged access times.
What are the Benefits of Multimedia ICs?
Multimedia chips provide various benefits to any multimedia system, some of the advantages of multimedia IC include:
Multimedia IC processor
- Real-time coding and decoding video and audio coupled with the creation of computer graphics.
- Execute other tasks such as file management and security
- Help save on the cost by providing a single media system for different forms of media

- Maximize flexibility since it integrates several interfaces and multiple functions in a single multimedia system.
What is the Function of DSP on Multimedia Chip?
A digital signal processor (DSP) is a function-specific microprocessor.
Or, a SIP block chip having an architecture attuned for the operational requirements of digital signal processing.
They are fabricated on MOS IC chips, with the main goal of measuring, compressing or filtering continual real-world analog signals.
Dedicated DSPs always boast of high power efficiency, this makes them appropriate for portable devices like mobile phones.
DSPs commonly utilize special memory architectures that are capable of fetching multiple instructions or data at the same time.
Digital signal processor also executes data compression, with Discrete Cosine Transform as the commonly utilized compression technology.
The common applications of DSPs include:
- Audio signal processing
- Digital image processing
- Sonar and speech recognition devices, and
- Consumer electronic gadgets like disk drives, mobile phones, and high-definition television (HDTV) items.
Which is the best between FPGA and ASIC Multimedia IC Technology?
ASICs can be either semi- or full-custom designs, this means higher costs of development particularly during design and execution phases.
Additionally, ASICs are non-reprogrammable after production; therefore modification in design attracts extra cost.
Even though ASICs have a comparatively higher nonrecurring expense, they are a good option because of the following reasons:
- ASICs normally have higher density and is able to incorporate complex elements into a chip. This provides limited size, low cost designs, as well as low power.
- ASIC designs ensure minimal resource wastage due to its custom characteristic, which ensures careful consideration of the number of transistors.
- ASICs are the perfect option when fabricating large number of designs intended for a specific application.
Advantages of FPGAs lie in their cost-effectiveness, reprogrammable capability and flexibility.
For instance, the reprogrammable feature enables fabricators and designers to modify the design or send patches even after selling the products.
Moreover, based on FPGAs, customers can develop their prototypes.
This facilitates full debugging, testing and updating of their design before fabrication.
Though it has limited nonrecurring cost, thus short time to market, some FPGA resources are wasted.
This is because specific FPGA types require standard resources and package.
Furthermore, when evaluating the cost of production with regard to the production volume, utilizing FPGAs gets more expensive in comparison to ASICs with increase in volume.
Moreover, because it is not possible to fully customize FPGAs, you need to add certain specific analog blocks into the FPGA platforms.
These functionalities generally need to be executed by external ICs, thus further increasing the cost and size of the end product.
What are Advantages of VLSI in Fabrication of Multimedia IC?
Video processor chip
· Less Power Consumption
This is because each of the components of multimedia IC made using VLSI fabrication consumes small quantity of power.
In a large multimedia IC, the components are very tiny and packed together that the capacitance is greatly reduced, hence less power.
· Less Testing
You need to test each IC before using it if you fabricated the same chip from discrete integrated circuits and other components.
It would be really tiring when you need to test thousands of multimedia ICs.
In VLSI fabrication, the components of the multimedia IC are dedicated to one use.
Additionally, majority of them are positioned at the center of the VLSI, with no access for testing.
You are only required to test the function the whole IC was meant for.
Reliability of an integrated circuit is a function of the number of peripheral connections it has to the external environment.
Therefore, if the multimedia IC is fabricated with several smaller ICs linked together, then there exist numerous connections lowering its reliability.
However, VLSI fabricated multimedia IC has fewer connections thus higher reliability.
· Embedded Characteristics
After VLSI fabrication, a number of applications could enjoy commodity economics for the fabrication of an IC.
You could as well use the IC to solve various problems at different instances in time.
· Lower System Cost
By applying VLSI fabrication, you will realize reduced system cost when developing a low-volume multimedia IC.
For higher-volume circuits, the cost of production of fixed hardware is basically much lower.

Courtesy of VLSI, integrated circuits that would have occupied a very large space can now be reduced into very small size.
Here are the procedures involved in VLSI manufacturing of multimedia IC;
1. Silicon Manufacturer
This involves the melting of pure silicon at 1400 degrees Celsius in a pot.
This is followed by the insertion of a small seed having the needed crystal orientation into the molten silicon and then gradually pulled out at 1mm/minute.
2. Wafer Processing
The silicon crystal, in some instances also containing doping, is produced as a cylinder with a diameter of ranging from 8-12 inches.
The cylinder is cautiously sawed to thin disks referred to as wafers that are later varnished and labeled for crystal orientation.
Lithography involves transferring patterns to every layer of the multimedia IC.
The wafer is processed to physically pattern every layer of the integrated circuit, and lithography procedures include;
- Application of photoresist which entails spin-coating the surface to be designed using an organic polymer sensitive to light known as photoresist.
- Printing involves transferring of mask patterns on the photoresist through the help of UV light exposure based on the kind of photoresist. The unexposed or exposed surfaces get resistant to some types of solvents.
- Development where you chemically remove the soluble photoresist.
The photoresist functions as a mask patterning the coated layers before you remove it.
4. Oxide Growth and Elimination
This process involves growing oxide from silicon by heating up in an oxidizing atmosphere gate oxide.
Oxide can be grown from silicon through heating in an oxidizing atmosphere Gate oxide.
Deposition of silicon dioxide on elements other than silicon via reaction between oxidizers and gaseous silicon compounds.
This provides insulation between the various layers of metallization.
After patterning the required shape with photoresist, the etching process follows to remove unprotected materials.
You can apply either wet etching (applies chemicals) or plasma or dry etching (applies ionized gases).
5. Diffusion and Implantation of Ion
Here, you add doping materials to modify the electrical properties of silicon via:
- Diffusion where you deposit dopants on silicon via the lattice through thermal diffusion, which is a high-temperature procedure.
- Ion implantation which entails impinging of highly energized acceptor or donor atoms on the silicon surface and move below it.
The patterned silicon dioxide acts as drain regions and implantation mask.
This is a high-temperature procedure that enables doping impurities to disperse further into the wafer.
Thermal annealing helps in repairing lattice damage due to collisions with ions used in doping.
7. Silicon Deposition
Silicon films can be incorporated on the wafer surface.
This involves metal layers deposition through evaporation.
In this step, you test the chip for manufacturing and design errors and ensure that it operates. Any wafer defect or single dust particle kills a die.
You should test each component before packing the multimedia IC.
10. Assembly and Packaging
This involves tape-out, fabrication of final layout optimization of the wafer for throughput and eventual packaging.
What is the difference in Multimedia Video Integrated Circuit vs. Multimedia Audio Integrated Circuit?

Multimedia audio ICs that employ a blend of CMOS and bipolar technologies are capable of minimizing decibel (dB) levels of tone steps and volume, distortion and noise.
Sound IC can be found in different types of integrated circuit package.
How can you Test the Quality of Multimedia IC?
Fundamentally, a test is carried out between every integration phase to reduce the cost of faulty devices.
Typically, multimedia IC quality testing involves two tests, that is the characterization and production test.
The characterization test is carried out after the production of the first dies.
The objective of this test is to verify the functionality of the multimedia IC, but particularly to evaluate the circuit performance.
This is instrumental in determining all the parameters that will be included in the component datasheet.
The datasheet entails static (DC) parameters like current capability, leakage, output voltages, and input levels.
Moreover, it determines dynamic (AC) variables such as operating frequency, hold and setup times, propagation delays, among other parameters.
There is no timing constraint for the characterization test and a couple of minutes is acceptable.
It must give accurate statistical data and information so as to establish a range of admissible values for every variable of the datasheet.
Remember, the datasheet is legal document which specifies the guaranteed performances.
On the other hand, the purpose of the production test is to verify that the manufactured multimedia IC satisfies the information on the datasheet.
Since the production test is carried out on each integrated circuit, it has to be performed very fast.
Production test involves a flowchart execution of elementary tests, with each having a straightforward pass/fail outcome.
Doing so allows you to determine the origin of failure and carry out sorting for both bad and good ICs.
You consider the production test accurate after foundry at wafer sort and subsequent to packaging (final test).
What are the Quality Standards for Multimedia ICs?
