Advantage And Disadvantage Of Decoder

It is little and small chip additionally has more data for programming. it covers with fan cooling to secure the CPU and influence quick to speed.

If large amounts of high-speed non-volatile memory could be integrated onto the CPU (Figure 1 2), the need for a hard drive (storage) and a motherboard could also be eliminated. This computer-on-chip concept can deliver > 1000x improvement in computation speed using a fraction of the power compared to the conventional computers.

In terms of physical power and redundant hardware, along with circuit diversity requirements – it becomes more beneficial to leverage an existing model that has this service already established.

Aziz and M. D. Pham [4] proposed a designing of LDPC decoders utilizing a collection of high level modeling tools in this paper. The Coding Gain, Throughput and Power Dissipation are the advantages of LDPC codes. The disadvantages of the LDPC decoder using traditional HDL based approach are the complexity of hardware implementation, time consuming and difficult to meet the real time requirements of communication systems. The programmable logic design beginning from high level modeling to FPGA implementation in all the ways is upheld in this new methodology. The methodology has been used to outline and actualize delegate LDPC decoders. The validity and productivity of the novel advanced level design approach is demonstrated by constituting the simulation and implementation results in this

Memory and clock cycle are the major players that determine the speed of a computer. Random access memory or RAM is controlled by bus width and bus speed. (Tyson, 2007). The width of a bus is the number of bits that can be sent to the CPU simultaneously and the bus speed refers to the number of times a group can be sent each second. A bus cycle occurs every time data moves from memory to the CPU. (Tyson, 2007). RAM and the bus cycle are directly related to the perceived speed of a computer. A clock cycle is the measure of a CPU's processing speed. Processing speed is also known as megahertz. For example, an 800 MHz Pentium III can potentially process 4 bytes simultaneously, 800 million times per second. Clock cycles or megahertz play an important role in the speed of a computer. Storage devices such as the hard drive, CD ROMS and floppy disks can affect how fast a computer functions also. Generally, information is retrieved from the hard drive faster than from CD ROMS or floppy disks.

Power optimize by embedded system devices is a critical concern. There is always require to long term battery life and/or reduce the environmental effect of a system.In past, this was purely a hardware issue, but those days are history.Now a days embedded systems software takes an increasing control for power management.

• Size. Incorporated circuits are significantly littler—the two transistors and wires are contracted to micrometer sizes, contrasted with the millimeter or centimeter sizes of discrete segments. Little size prompts focal points in speed and power utilization, since littler parts have littler parasitic resistances, capacitances, and inductances.

The functional diversification of the semiconductor based devices by non-digital components is More than Moore implementation. These non-digital functionalities may not scale at the same rate as the digital components. The non-digital components are capable of interacting with outside world through sensors and actuators. This integration of functions like analog and mixed signal processing, addition of passive, power components and bio chips increases the range of applications such as communications, automotive, biomedical and security. As integration grows so does the challenges, it demands the need for multidisciplinary research programs to run in pace with growing scientific fields.

The multinational company brands its Quad-Core microprocessor as “The Ultimate multi-core performance”. This innovative piece of technology is basically designed for desktop personal computers. Enabled with a powerful multi-core technology, the Quad-Core chip is designed to handle immense computation and visualization workloads. Providing all the bandwidth needed by users, the latest four-core Intel Core 2 Quad micro-architecture provides a faster, cooler, and quieter desktop and workstations. The unparalleled performance of the Intel Core 2 Quad processor is achieved by each of the four complete execution cores providing the full power of Intel Core micro-architecture. With this, more instructions can be achieved per clock cycle, shorter and wider pipelines read and implement commands more quickly, and improved bus lanes move data throughout the system faster. As Intel has declared on their webpage, “This quad-core processor represents Intel’s continued leadership and drive of multi-core processing and more parallel computing”8. The microprocessor company continues to elaborate that the latest versions, developed around Intel’s 45nm manufacturing technology, take the stated benefits to “a whole new level”. This new technology utilizes hafnium-infused Hi-k transistors, providing even more processor performance by doubling the transistor density, improving efficiency and speed relative to the previous generation,

The goal and aim of this report is to cement an understanding of the difference between a router and a multi-layer switch, the benefits either provides and most importantly when you would want to implement one rather than the other, for instance are multi-layer switches simply better? How much do they cost compared to a router, can I justify this cost with performance? Tradionally routers were deployed in networks to route packets throughout the network and to other networks using their software in a method called packet-switching whilst switches in a network traditionally connected hosts to the network and employed a method called Hardware-based switching and only concerning themselves with information at the data link layer. New advances in technology have redefined the role these devices play in the network today with the introduction of the Multi-Layer Switch, switches are able to examine information from the data link layer(layer 2) to the application layer(layer 7) paving the way for hardware based routing. This report will be threefold; first we will look at the standard router, and what it does then we will look at the multilayer switch and what it does then we will look at them together to conclude and fully understand the difference between a router and a layer 3 switch.

Abstract—This Paper includes the development of domino CMOS technology for the design of XOR gate. Low power dissipation is one of the main design considerations for high level performance circuits. The leakage power dissipation is controlled by the factor gate oxide leakage and threshold leakage and thus the overall leakage of domino XOR circuits. To show the efficiency of the proposed model, a simple example like implementing of XOR gate with P type domino XOR, N type domino XOR gate and PN mixed domino XOR gate, an average power dissipation reduced up to 66.15% and propagation delay is 46.66%
