Message Sample
Parameter
Example Value
Absolute path of DSP executable
windows\loop.out
Buffer size
1024
Number of iterations
10000
The sample can be executed for infinite iterations by specifying the number of iterations as 0. The
following example initiates the loop sample application to run for 5000 iterations each transferring a buffer
of size 2048 bytes.
Windows CE>s loopgpp.exe windows\loop.out 2048 5000

Figure 4-3
illustrates basic message transferring concepts in DSP/BIOS LINK. It transfers messages
between a task running on GPP and another task running on the DSP. On the DSP side, this application
illustrates use of TSK and SWI with MSGQ.
