This paper describes trancell, a translator and associated runtime environment that allows programs written in the occam programming language to be run on the Cell BE microarchitecture. trancell cannot stand alone, but requires the front end from the KRoC/Linux compiler for generating Extended Transputer Code (ETC), which is then translated into native Cell SPU assembly code and linked with the trancell runtime. The paper describes the difficulties in implementing occam on the Cell, notably the runtime support required for implementing channel communications and true parallelism. Various benchmarks are examined to investigate the success of the approach.
