Yeah, eventually.
Analog Devices 2105's cost $12 in quantity 1.
They are capable of doing 2 data moves, a 16x16 multiply, a 40 bit
accumulate and a prefech of the next instruction all in 100ns.
10 Million Multiply-Accumulates per second. Ever tried that on a 386?
For more money, you can get ones with 60ns clocks (16.7 MACS).
