Abstract :
We have implemented a number of real-time signal processing kernels and applications within the Ptolemy simulation and code generation environment. Our goal is to make it easy to generate real-time programs with configurable interactive user interfaces. As part of this project, we have developed and benchmarked some key signal processing kernels for the new UltraSparc Visual Instruction Set. We present some performance results and compare the VIS with plain integer and floating-point C code running on the same processor.
