Bit string data processor using dynamically addressable bit locations in memory so overlapping strings do not destroy data in memory

摘要

A data processor in accordance with the present invention can normally operate bit-string data while avoiding a breakage of the data even in the case where a read-out area of the bit string and a write-in area thereof are overlapped by each other by providing an operation code of an instruction with an option designating the direction of bit processing.
