Currently, chip multi-core processors are mainly developing in two directions: multi-core processors consisted of a few complex cores (Traditional Multi-core Processors, such as servers and desktop CPUs) and many-core processors consisted of many simple cores (Multi-core Stream Processors, such as GPUs).They both have own advantages and disadvantages. Traditional Multi-core Processors are designed for different kinds

In recent years, with increasing number of modules in multi-core designs, it is more difficult to distribute a single synchronous clock to the entire chip. The complex clock tree also leads to high power consumption. In order to solve this problem, globally asynchronous locally synchronous (GALS) systems have been proposed, in which the entire design

Advances in VLSI design techniques and increasing requirements in DSP’s performance have made Multi-DSP a reality and a necessary consequence. The complexity of these Multi-DSP and the traditional on-chip bus is not suitable for the Multi-DSP call for review and revision of on-chip communication techniques. Network on Chip(NoC)has been suggested as the communication resource to

Due to multi-thread parallel processing, the significant rise of performance and efficiency, multi-processor instead of single-processor rose as the main stream processor. However, high temperature and power consumption threat regarding reliability and lifetime of processors, has become the bottleneck of multi-processor development.Dynamic Voltage and Frequency Scaling (DVFS) and clock gating technology are used to solve

At present, the computer has become an indispensable tool in people’s life and work. In use, higher and higher demands on the computer are wanted, a higher processing speed, greater storage capacity, more convenient and friendly usage and so on. In order to improve the speed of the processor, manufacturers constantly improve the frequency of

High-power and high-heat processor has always been bottlenecks of computer system’s design. For their own characteristics of applications, the system performance and power consumption of embedded system have more stringent requirements. Therefore, the study of low-power techniques is of utmost importance to research and development of embedded system. Especially in recent years, rapidly increasing demands

With the continuous improvement of integrated circuits and computer techniques, the multi-core architecture provides a powerful ability to enhance the overall performance of the current processors. However, memory developed relatively slower which imposes bottleneck on the computer performance. Therefore, how to improve the performance of in multi-core architecture emerges as a hotspot and multi-port memory
