to operate in parallel on related data. An example of the latter is graphics rendering, in which multiple ALUs perform the same operation in parallel on a group of pixels, with each ALU operating on a pixel within a scene.

Implementation

An ALU is usually implemented either as a stand-alone integrated circuit (IC), such as the 74181, or as part of a more complex IC. In the latter case, an ALU is typically instantiated by synthesizing it from a description
