%T The Kent Retargettable occam Compiler

%X A generic approach to targeting occam to non\-transputer
   architectures is described. The principle is to build a
   register\-level emulation of the major design elements of
   the transputer, using native registers of the target
   hardware, and reuse the standard occam toolset compiler with
   as little alteration as possible. The porting effort thus
   reduces to an architectural mapping rather than involvement
   in the compiler and code\-generator. An immediate payoff
   comes from reuse of a well\-developed and sophisticated
   compiler. An important scientific question, with relevance
   to efficient and portable parallel computing, is whether the
   crucial benefits of transputer architecture (such as the
   very low overheads for the management of processes and
   events) can be transferred through such emulation. We report
   some initial results for SPARC\-based targets.

%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.
