Summary :

The strong demand for complex and high performance system-on-a-chip requires high performance microprocessor core and quick turn around design methodology. We have developed 128-bit synthesizable core processor and tile based quick turn around design methodology. It is 200 MHz MIPS compatible processor with 128-bit SIMD extension and is targeted for consumer electronics. We also developed an ASSP including the processor core, SDRAM controller, 2 PCI and 2 MAC mainly for network applications. For SOC development, we developed a tile based design methodology aiming at quick design convergence. The initial RTL design is synthesized and partitioned to several tiles by in-house tiling tool. It promises quick turn around from RTL design to tape out using the concurrency of the back-end design.
