C2901
4-bit Microprocessor Slice
Megafunction
General Description
The C2901 four-bit microprocessor slice megafunction is a cascadable ALU intended for use in
CPUs, peripheral controllers, and programmable microprocessors. The megafunction includes a
dual port RAM, ALU, shifter, register and multiplexer. The microinstructions of the C2901 allow
for easy modeling of various microcontrollers.
Features
⢠Independent and simultaneous access to two registers save machine cycles
⢠Eight function ALU
⢠Expandable â Any number of devices can be connected for wider bus structures
⢠Four status flags for Carry, Overflow, Zero and Negative
⢠Microprogrammable
⢠The C2901 was developed in HDL and synthesizes to approximately 1,300 gates
depending on the technology used.
⢠Functionality based on the Advanced Micro Devices AM2901
