bit slice

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.
