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
