SOCs designed for embedded systems are now widely used on embedded multimedia devices. Processors in these devices may need capabilities to support some compound computations, and the most important of all is multiply and accumulate (MAC) operation. Thus DSP processors or special ALUs are designed to accelerate these computations. Besides the computation issue, how to improve the reliability, stability...
In recent years, microcontrollers are largely used in varieties of different systems, especially on small embedded systems, small device controllers, and e-devices. Different from general systems, processors inside these systems may not need very powerful computing capability; however, reliability, robustness, low EMI, and low power are the most important criteria. It is a well-known fact that asynchronous...
With the VLSI technology improving rapidly, SoC has been becoming the most important VLSI application. However, clock distribution and low power have already become the two most important issues in SoC design. In addition, it's also a very important issue to integrate IPs that can perform operations correctly with different clocks. Asynchronous circuits may resolve these problems by removing the “clock”...
Nowadays, MPSoCs or multicore processors have been becoming the major trend of system or processor designs. Thus the design of interconnection networks becomes the most important issue of all. However, lots of different problems may arise in the network design and they should be carefully handled. It is widely known that most of these problems can be resolved easily by asynchronous circuits. But because...
Microcontrollers are widely used in many handheld devices and embedded systems. Thus, low power, reliability, and robustness have been becoming the critical issues for these microcontrollers. Asynchronous circuits may be one of the best solutions to answer these problems. It is widely known that the 8051 processor is the most popular 8-bit microcontroller; however, because of its CISC nature, the...
