Abstract
PURPOSE: To enable to give the compratively small size unit the advantage of information prefetch or post-writing processing, by providing the byte aligner circuit to the buffer register between the memory unit and the access request unit.
CONSTITUTION: Based on the content of the N sets of address registers 2 pointing out the present processing address, the prefetch address and/or post stored address production circuit 4 and memory unit 1 are provided and the prefetch of information or post writing of information processing is made with microprogram. In this data processor, the buffer register 5 storing a multiple byte of 2P bytes and the arrangement unit having byte aligner circuit 6 are taken as a pair and the pairs are provided by N sets corresponding to the register 2. Further, the information giving and reception between the memory unit 1 and the arranging unit pair is made in word unit and that between the arranging unit pair and the access request unit is made in the form of continuous information via the aligner circuit 6.
