Jeff - Re: " IF your putting more cache on the same chip then why L2? - Why not just a larger L1"

The L1 cache controller is designed to cache 32 K Bytes. This would have to be redesigned and the chip "split apart" to drop in the extra SRAM cells to enlarge the L1 cache.

From an implementation strategy, it is simpler to just "bolt" the extra cache on to the end of the CPU chip and run the appropriate address/data lines from the on-chip L2 cache controller (already on the CPU).
