Data processing circuit and method for determining the first and subsequent occurences of a predetermined value in a sequence of data bits

摘要

An apparatus and method is provided for determining locations of a predetermined value in a sequence of data bits. Each location is determined independently of the others thereby allowing them to be found more quickly. This has particular application to block memory loads and block stores to memory, wherein ones in the register list in the instruction word indicate the registers to be loaded or stored. Thus, in these applications the present invention enables the positions of these ones to be determined quickly.
