%X 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.
