one of the first layers of abstraction that arises is the Arithmetic Logic Unit. The ALU takes in two sets of data, performs a chosen math function, and outputs one data set as the result.

implementing entire functions that would now be integrated. One of the more famous of these devices is the 74181, a cascadable 4-bit arithmetic logic unit, or ALU. An ALU is the heart of a ...

It also represents an advance because these ultra-tiny nanocircuits can be programmed electronically to perform a number of basic arithmetic and logical functions. "This work represents a quantum ...

CPUs consist of a processing unit called an ALU (arithmetic/logic unit), a control unit that controls how ... MCUs require less power than a CPU, but a CPU is better for coordinating a variety of ...
