TMS320F280049M: CLA program memory

Part Number: TMS320F280049M

Hi,

Customer is evaluating F28004x for servo driver.

Currently they faced one issue, the limitation of RAM size. Especially when CLA is used, the RAM size for C28x is less. Actually, customer needs about 140KB.

Is there any solution?

What about CLA ROM? Can it be used for application code?

Thanks a lot.

Br, Jordan

    CLA ROM cannot be used for application code. It is read only memory.

    In case you run out of memory, you may be able to "boot" in sections of memory/code to RAM. If you have the cycles available in your application, you can ping-pong the code into RAM. Meaning you can copy the code you need into RAM, and then replace that with some other code when you need it. And continue to do this as needed.

    If this does not work, you may need to consider a device with a larger amount of RAM space. Perhaps F2807x.
