Bit slice
<architecture> 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.
