Maxwell,

Probably. You have to remember that the director of K7 is a guy who
co-designed the Alpha 21264. He probably has done some simulation
already and knows what best. He has taken a lot of design in Alpha
to bring into K7.

I just hope he stole the FPU ;-)

Now that I think about it the latency of 2 is about correct. Remember
that the fastest SRAM is currently about 2ns. At this response the
fastest speed is 1/2ns=500MHz. Thus to get the speed beyond 500MHz
higher latency of 1 is a must. Otherwise the CPU and L1 is out of
synchronization.

Maxwell are you implying the minimum ammount time required to switch a SRAM from 0 to 1 or vice-versa is 2ns. This doesn't seem right to me. This would seem to indicate that a transistor can only switch at 500Mhz.. I just can't see how there can be a limiting speed (ofcourse I'm not putting much thought into it yet... I'll let you explain first) ;-)
