Abstract :
This paper describes four techniques for tuning instruction customisation for reconfigurable system-on-chip (SoC) devices. These techniques involve tuning custom instruction granularity, tuning custom instruction hardware, tuning based on run-time information, and instrumentation for tuning analysis. The proposed approach has been used in deriving custom instructions for advanced bit manipulation applications for the Mi-croBlaze processor. We show that for a transfer coding application, custom instructions with an increase of 23% in area can improve performance by 13 times.
