Automatic synthesis and scheduling of multirate DSP algorithms
- To date, most high-level synthesis systems do not automatically solve present design problems, such as those related to timing associated with the physical implementation of multirate DSP architectures. Whilst others do not trade off area/speed of algorithm efficiently for such architectures. An automatic synthesis methodology based on both retiming techniques together with folding transformations is presented in this paper in order to solve timing problems associated with the implementation of multirate DSP algorithms. We demonstrate that techniques for modeling computational unit latencies, which can influence parameterisations of a multirate DSP IP core, can lead to highly efficient solutions. This is illustrated using a polyphase IIR IDCT example. Using the folding transformation, the control circuit for a hardware sharing multirate DSP is also presented.
