    Abstract

    This paper summarises the experiences gained at the Control Laboratory of the University of Twente in porting the Kent Retargetable occam Compiler -KroC -to the Analog Devices' ADSP21060 SHARC Digital Signal Processor. The choice of porting the KRoC to the DSP processor was in our view both a challenge and an absolute necessity because DSP processors are an important ingredient in modern day control systems. Currently, our implementation contains the most important occam primitives such as channel communication, PAR, ALT, and most of the integer arithmatic. Furthermore, a basic kernel was realised, providing channel-communication based scheduling only. This porting process, using quite straight-forward modifications of the SPARC KRoC-translator, was done within six weeks. A representative benchmark was constructed, showing that the 33Mhz SHARC-KRoC implementation is 40% faster than the the 25Mhz T800 using the INMOS D7205 Toolset.
