A technique for constructing a processor from modules, each of which processes one Bit-field or "slice" of an operand. Bit slice processors usually consist of an ALU of 1, 2, 4 or 8 Bits and control lines (including carry or overflow signals usually internal to the CPU). For example, two 4-Bit ALUs could Be arranged side By side, with control lines Between them, to form an 8-Bit ALU. A sequencer executes a program to provide data and control signals. The AMD Am2901 is an example. (1994-11-15)
