So the scratchpad isn't so much programmer controlled as just a L1 cache level?

  I would not call it a cache as it is: 1)Physically addressed 2)Has no complex control logic (TLB, CAMs, additional flags) 3)Us not just simply replicating something higher up in a memory hierarchy A programmer will have full access to be able to handle memory however they want, but we want to be able to build out the tools to allow for a programmer to treat it similarly to an L1 cache (that is part of a shared memory space... that has different access times)

    Interesting. I look forward to playing around with one.

    So the scratchpad memory contains instructions as well as data?

    @wglb: That is the plan for now. An instruction cache is possible, but we don't see the need to add extra complexity.
