Who Needs to Read This Chapter
User software is required when a user wishes to add some own functionality like DSP effects to VS1003.
However, most users of VS1003 don’t need to worry about writing their own code, or about this chapter,
including those who only download software plug-ins from VLSI Solution’s Web site.
10.2
The Processor Core
VS DSP is a 16/32-bit DSP processor core that also had extensive all-purpose processor features. VLSI
Solution’s free VSKIT Software Package contains all the tools and documentation needed to write, sim-
ulate and debug Assembly Language or Extended ANSI C programs for the VS DSP processor core.
VLSI Solution also offers a full Integrated Development Environment VSIDE for full debug capabilities.
