A computer is, at its core, just a bunch of transistors wired together. Once you have enough transistors on a board, though, one of the first layers of abstraction that arises is the Arithmetic ...

Communicates with the rest of the components by using the control bus The Arithmetic and Logic Unit (ALU) is where the CPU performs the arithmetic and logic operations.

His latest is a reverse engineering of the 74181 Arithmetic Logic Unit (ALU). The great news is that the die image and complexity are both optimized for you to succeed at doing your own reverse ...

Since arithmetic and logic operations within processing ICs are a crucial factors for speed, we developed a new approach to the ALU.

It depends — you can have arithmetic instructions like addition and subtraction, logical operations like AND and OR, and many others. These are handled by the CPU’s Arithmetic/Logic Unit (ALU).

Power consumption control in logic circuits, long a feature of forward looking papers from Japanese companies at ISSCC, hit the conference mainstream last week when Intel presented a paper on a 4GHz ...
