Can SRAM be designed for unified cache/eDRAM functionality (RSX)?

[j^aws]

OK, but TurboCache actually refers to the architecture integrating memory distant from the GPU (i.e. on the other side of the PCI Express bus in a PC) and making it appear to be part of local memory.

In PS3 the TurboCache memory would be the XDR. It's a complete misnomer (it's not a cache at all, just non-local memory) and I wasn't clear on which bit of cache you were expecting could serve as dual-use, the actual L2-texture cache or "TurboCache".

I've already explained this earlier to Aaron, I'm referring to the L2 Texture Cache.

I've also speculated on this board that the PPE L2 cache may/may not be cache coherent with RSX L2 cache via the FlexIO bus with a few patents I posted... Basically this L2 cache would have multiple modes, e.g. a tile cache, texture cache, eDRAM etc...

Hmm, explains why northern chicks always have 5 o'clock shadows!

Not all, just the ones you go after
