Arithmetic Logic Units are combinations of digital logic gates that performs arithmetic and logical operations on binary numbers. For this project, an 8-bit ALU was made entirely of NAND gates only. A ...

[TGTTGIT] recently took the plunge and decided to build his own computer using logic chips. He just completed a 4-bit ALU which can compute 18 functions. It took a long time to get the wiring right, ...

In this paper VHDL implementation of 8-bit Arithmetic Logic Unit (ALU) is presented. The design was implemented using VHDL Xilinx Synthesis tool ISE 13.1 and targeted for Spartan device. ALU was ...

ALU (Arithmetic Logic Unit) is the fundamental unit of a microprocessor which performs all the basic operations based on the control input selection. There are separate units which work independent of ...
