Just for the sake of completeness:You can turn L2 memory, which defaults as RAM, into Cache by using the CSL or by programming few bits. L2 can infact be confirgured to upto 4-way set associative cache. Sort of an un-clever word which implies that you can turn on or off any of the four 16kb section in a 64kb L2 size, into a cache as and when required.

Gustl is correct L1P and L1D are always enabled for c64x and c671x devices.

 

Goto TI document spru190.pdf and look for the document number for something like 'c64x two level memory'...

I don't think you can turn them off! At least for 67x they are always on
