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.
