Efficient implementation of DSP applications are critical for many embedded systems. Optimising compilers for application programs written in C, largely focus on code generation and scheduling which, with their growing maturity, are providing diminishing returns. This paper empirically evaluates another approach, namely high level source to source transformations. High level techniques were applied to the DSPstone benchmarks on 3 platforms: TriMedia TM-1000, Texas Instruments TMS320C6201 and the Analog SHARC ADSP-21160. On average, the best transformation gave a factor of 2.43 improvement across the platforms. In certain cases a speedup of 5.48 was found for the SHARC, 7.38 for the TM-1 and 2.3 for the C6201. These preliminary results justify further investigation into the use of high level techniques for embedded compilers.
