Mary,

The uses that people will demand of microprocessors that you design will amaze you. I just don't think that you will be able to keep with memory bandwidth and other demands that will be made of your microprocessors.

Memory bandwidth on traditional microprocessors is a generally misunderstood topic. Processors have traditionally moved memory in very small chunks (a cache line) at a time. The introduction of SSE has changed that paradigm somewhat, as there are now instructions specifically directed at moving DRAM data.

It will be interesting to see how all this converges, but the arrival of high bandwidth memories (DRDRAM and DDR) seems to be occuring at the right time.

One thing to consider is the arrival of embedded DRAM. This offers bandwidths orders of magnitude higher than either DDR or DRDRAM. Sony PS/2 uses it, and I expect that it will become prevalent in the next few years.
