Does anybody have experience on using shar memory for multiprocessors?

Started by Paul May 8, 2006
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

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.
