Part Number: TMS320F28375D

hi,

We are using TMS320F28375D in our application. We want to use CPU1 as master and CPU2, CLA(both) as slave.

So i required to share some data to all of them.

I can share data to CLA of CPU1 using local share memory and to CPU2 using global shared memory.

Can I share data form CPU1 to CLA of CPU2?

Regards,

Hi Himanshu,

Direct sharing of data between CPU1 and CLA (of CPU2) is not possible. You'll have to share the data to CPU2 and later CPU2 can share with its CLA.

This is not possible. Guatam made a good suggestion.

LS (local shared) RAMs can share between CPUx and CLAx
GS (global shared) RAMs can share between CPU1 and CPU2.
