Software Estimations for DSPs Improved Design Flow Shortens Time-to-Market

摘要

Generation of optimized DSP code from a high level language such as C is very time consuming since current DSP C compilers are generally unable to produce efficient assembly code. In this paper we present a DSP software estimation methodology from a C description of the application. We provide both a performance evaluation for the real generated assembly code and an estimation of an optimized assembly code. This information help designers to improve the DSP software development and then reduce time-to-market Although our tool, VESTIM is based on the VLSI Technology WF3500 DSP Core which stands for the DSP Group OakDSPCore™ , it may be easily adapted to support other DSPs.
