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 – 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
