L2 Shared Memory example

Hi all,


I am looking to create a buffer of parameter data values in L2 memory. Approximately 2kb in size.

The buffer need to be write-only from the ARM core, read-only from both Sharc cores.

I also need raise an interrupt on the Sharc cores when the data is changed in the buffer.

I have looked over the documentation and I can't find a suitable example of this. Could anyone offer me some ideas and routes ?


I did attempt to use the E-377 MDMA/MCAPI talkthrough example as a base, however it appears that the MDMA interrupts from ARM to Sharc are different to Sharc to Sharc which is demonstrated in the E-377.


Any help or direction this would be gratefully accepted.


Best wishes
