[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 ...

Bit slice processors usually consist of an arithmetic logic unit (ALU) of 2, 4 or 8 bits and control lines. Using multiple, simpler ALUs was seen as a way to increase computing power in a cost ...

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