Due to the advancing semiconductor technology it is becoming possible within ten years to fabricate a highly complex and high performance VLSI that includes more than hundred million transistors on a single silicon chip [1]. Using such a technology, socalled systems-on-a-chip, that includes CPU cores, DSPs, memory blocks (RAM and ROM), application specific hardware modules, FPGA blocks, as well as analog and radio frequency blocks, as shown Figure 1. Systems-on-a-chip will be suitable for embedded applications, such as consumer electronics products that perform sophisticated data and information processing, telecommunication equipment that perform movie picture and audio transmission, control systems for industrial manufacturing, automobile, and avionics.
