Abstract
A bit-slice digital processor for performing an N-point correlation or convolution of N single-bit coefficients with a bit parallel, word serial, bit-staggered stream of M bit data words. The processor includes an N row, M column array of one-bit gated full adders with rows extended by half adders to accommodate word growth. Intercell connections incorporating clock activated latches provide for data and result flow unidirectionally down columns, one at twice the rate of the other. Carries and coefficients move unidirectionally along array rows at the faster (data or result) rate. Complex computations are executed by arrays of processors each with output delaying means and an adder to sum separate processor contributions. The processor may include data and result bypass connections subdivided by clocked latches for bypassing without operating speed penalties, as required for fault-tolerant processor array construction.
