Abstract
A programmable bidirectional shifter is disclosed comprised of a first bidirectional load and read interface circuit selectively activated for left shifts, and a similarly constituted second bidirectional load and interface circuit which is selectively activated for right shifts. The first interface circuit is coupled to a byte shift matrix while the second interface circuit is coupled to a bit shift matrix. The byte shift matrix is arranged and configured to shift the input quantity by a multiple of bytes, namely multiples of eight bits. The bit shift matrix is similarly constituted to shift its input quantity by a selected number of bit locations up to seven consecutive places. The bit and byte shift matrices are coupled to allow bidirectional flow of signals therebetween. The bit and byte matrix are controlled by a bit and byte shift control circuit respectively which determines the number of bytes and bit places each matrix will actually shift.
