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 ...

Central Processing Unit (CPU) is the heart and brain of every computer. Every single operation that you do with your computer is processed in CPU. The performance of your computer is based on its ...

We see a lot of discrete-logic computer builds these days, and we love them all. But after a while, they kind of all blend in with each other. So what’s the discrete logic aficionado to do if they ...

Editor’s Note: In this series of articles based on his book – Design Recipes for FPGAs – Peter Wilson provides a basic quick overview of VHDL (VHSIC hardware description language) followed by ...

An elementary electronic circuit in the arithmetic logic unit (ALU) of the CPU that adds one bit to another. The output of the half-adder is a result of 0 or 1 and a carry of 0 or 1. Additional ...

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 ...

There’s much truth in the advice that, to truly understand something, you need to build it yourself from the ground up. That’s the idea behind [Christian]’s entry for the Re-engineering Education ...

Forty years ago today, electronics and semiconductor trade newspaper Electronic News ran an advertisement for a new kind of chip. The Intel 4004, a $60 chip in a 16-pin dual in-line package, was an ...

The central processing unit (CPU) is either a dedicated integrated circuit (IC) or intellectual property (IP) core on an IC that processes logic and math. A CPU can handle high-level provisioning of ...
