Also, cache management is often important to consider when going across
processor boundaries (and even across component ownership of buffers!).
Just posted this to try to capture many of the cache issues:

Feel free to correct errors (I did my best... but cache management is
quite tricky). ;) If you want to discuss details, I might suggest
doing it on the "discussion" tab of the topic above so we capture the
chat.

Hello,
You can use CMEM driver for this task. And DSPLINK driver for
sending/receiving messages to/from DSP.

Hi everyone.
Does anyone in here able to use shared memory on the
GPP and DSP ? We're planning to implement a common
memory area where the GPP will store the unprocessed
buffer (GPP will then send message to DSP to start
processing the raw data), the DSP will then access
this area for processing then send the result information
back to the GPP.
Any information or reference on how I can accomplish
this shared memory area approach. Would it be possible
if I define a static area(address) on GPP and DSP side
where to store and read the unprocessed buffer ?
Any information on this matter is highly appreciated.
Regards,
Jowelle
