发明名称 Apparatus for processing character string moves in a data processing system
摘要 In a data processing system configured to transfer data in words and an apparatus is provided for manipulating, in response to a single manipulation instruction, the contiguous variable length sequence of data stored in bytes including an instruction decoder for decoding a single manipulation instruction, a memory for storing data in words where each but word includes a plurality of bytes, a circuit responsive to the command signal from the instruction decoder to access a contiguous sequence of the bytes from the memory wherein the first byte of the sequence is not stored on a word boundary, and providing the byte sequence to a plurality of data processing registers wherein the first byte of the sequence is aligned with the first registered boundary. Additionally the apparatus includes the capability to provide the contiguous sequence to memory wherein the first byte of the sequence is not stored on a word boundary. The data sequence maybe specified by the number of bytes in the sequence or by a sequence terminating character.
