Multicore SoC for embedded systems

Multicore SoC is one of the most promising approaches to realize high-performance. A SuperHtrade (SH) embedded processor core, SH-X3, implemented in a 90-nm CMOS process, achieved 1080 Dhrystone MIPS, and 4.2 GFLOPS, and is ready for multicore SoCs. Its power performance ratio reaches to as high as 3000 MIPS/W. Some multicore SoCs for embedded systems are developed, and we still have issues to solve for future multicore systems.
