hi, there, I am current setting up a project to use ADST TS101 TigerSHARC EZ-Lite board with two ADSP TS101 DSPs. I want to setup the program so that these two CPUs can communite each other via share memory. Does anybody have such experience on this filed? or Would you please give me some reference? thanks. regards paul
Does anybody have experience on using shar memory for multiprocessors?

As far as I know, the two TS101s on the EzKit are connected via their external bus, and as well there is external memory on that bus. Each TS101 can access the other's internal memory directly, with an address range determined by it's multiprocessor identifier. So it's as simple as accessing memory. As for layering on any shared memory software protection schemes, thats up to you. As far as a reference, try the TS101 manuals and the EzKit manuals. I'd be surprised if ADI doesn't have example code for this, and VisualDSP supports multiprocessor as well by allowing for shared variables to be declared and referenced.
