Abstract

A micro-computer system for data processing and for the rapid location of a characteristic block has a working store which is organized so that it can be used as a conventional working store with a data width of, for example, one byte. This working store contains a data file storage zone for storing, along with other data, a plurality of blocks of multi-byte characteristics. Several read-write stores, all of which contain one or more bytes of the block of characteristics, are read out simultaneously, while the data ports of the read-write stores are cut off from the data bus. The comparison with the combinations searched for is carried out via comparators which compare the data read from the read-write stores with the combinations searched for, which are intermediately stored. The outputs of the comparators are connected to the inputs of an AND gate which produces an identity signal which terminates the searching.
