Control DSP cache size on OMAP

Yehuda Bernstein

Hello,

What is the correct way to control the the DSP cache size on OMAP. I guess it's done by the CE framework somewhere but there should be a way to control it if I want, for example, L1P cache size to be 32kb instead of 16kb.

Yehuda,

I just noticed that this is a fairly old topic with no replies. Are you still seeking feedback?

Yehuda,

The C674x DSP Megamodule Guide ( http://www.ti.com/litv/pdf/sprufk5 ) defines the cache control registers on the DSP that set the cache size.

This could/should be defined in the server.tcf file.
