Sample Applications
This section provides basic information and examples for the various sample
applications, as well as code used to invoke the sample applications.
Figure 4-1
illustrates basic data streaming concepts in DSP/BIOS LINK. It transfers data between a task
running on GPP and another task running on the DSP. On the DSP side, this application illustrates use of
TSK with SIO and SWI with GIO.
