General Information
|
When is a CPU not a CPU? Answer: when it's a Bit-slice
microprocessor. The Bit-slice architecture is one of the most interesting
innovations in microprocessor design. The Intel 3002 was Intel's first
entry into the Bit-slice marketplace and the 3002 was the first bipolar
Bit-slice device. It is an unusual bit-slice in that it was a 2-bit device
while most others devices were 4-bit devices. It made up for it's limited
register width and instruction set with a large number of buses and
horizontal microprogrammability.
