Alu block diagram. Shift unit control unit. The alus output is the result of the. A block diagram showing alu. Use of the case structure will make this job easy.

The inputs to an alu are the data to be operated on called operands and a code indicating the operation to be performed. Then an external control unit tells the alu what operation to perform on that data and then the alu stores its result into an output register. Ee 231 lab 6 arithmetic logic unit the heart of every computer is an arithmetic logic unit alu. A single cpu fpu or gpu may contain multiple alus.

Depending on the value of the control lines the output will be the addition subtraction bitwise and or. This tutorial will teach you how to build an arithmetic logic unit alu from scratch using these simple logic gates and other components. Connecting digital circuits together. Digital electronics modules 2 to 5 have described how basic logic gates may be combined not only to perform standard logic functions but to build circuits that can perform complex logic tasks.

You can edit this block diagram using creately diagramming tool and include in your reportpresentationwebsite. It represents the fundamental building block of the central processing unit cpu of a computer. Alu block diagram the alu that you. Given the alu pseudo code below write the verilog code and draw its logical block diagram using only 1 full adder bitwise orand and as continue reading design a simple alu and draw its logical block diagram.

The carry look ahead adder was chosen as an optimum balance between circuit real estate and speed. Wikipedia the logic gate diagram. Components of primary concern are the following. An alu is a fundamental building block of many types of computing circuits including the central processing unit cpu of computers fpus and graphics processing units gpus.

An arithmetic logic unit alu is a digital circuit used to perform arithmetic and logic operations. The alu will take in two 32 bit values and 2 control lines. Block diagram of alu. 581 alu block diagram.

Both small scale integrated ssi and medium scale integrated msi chips are available in many forms that can be directly connected. An alu loads data from input registers. In this lab you will use the verilog language to implement an alu having 10 functions.
