Finished projects

In contrast to general purpose microprocessors, ASIP give much higher performance, lower power, and lower silicon costs because of the optimized application specific instruction set and microarchitecture.

ASIP research is a challenging area. The required knowledge for ASIP research is broad, ranging from applications, architecture selection, code compiling, parallel programming, microarchitecture, down to silicon fabrication. Our research demonstrates state-of-the-art ASIP concept designs. Our main academic interests include exploration of extreme performance with specific flexibility, low silicon cost, and low power architectures.

We focus on DSP (digital signal processor) and multiple processors including integration (SoCBUS) and hardware dependent programming issues. NPU (network processor unit) is also one of our research areas. To support the architecture design, ASIP design tools are continually developed for two purposes; microarchitecture synthesis and source code analysis. Source code analysis tool will explore design space by exposing data and program locality, opportunities of parallelization, and efficient parallel access of scratch pad memories. Applications covered by our research are radio baseband signal processing and other streaming signal processing.
