Abstract
A shift arithmetic device which has a circulating shifter for shifting N-bit information by a specified number of bits and a set circuit for setting logic 'O' or '1' in the shifted N-bit information at the bit positions corresponding to the specified number of bits shifted. A memory having stored therein N-bit patterns whose arrangements of logic '0' and '1' sequentially change and a bit arithmetic unit for executing logical processing, for each bit, between N-bit pattern read from an address of the memory corresponding to the number of bits shifted and N-bit information shifted by the circulating shifter.
