IPC: G06K7/00
Filed: 1992-05-29
Abstract: PURPOSE:To improve search efficiency by switching a retrieval unit from one byte to plural bytes when the specific code in data is retrieved. CONSTITUTION:When a code which has a meaning by using plural bytes is retrieved by the method for retrieving specific one-byte codes 2 and 3 in data 1 wherein a code having a meaning by one byte and the code having the meaning by the plural bytes are both present, the retrieval unit is switched to the plural bytes and the specific code 3 is retrieved.

Filed: 1984-07-04
Abstract: PURPOSE:To obtain the excellent effect of performance by applying an inter- control program branch system comprising an address conversion mechanism, a main memory control mechanism and a control program reading mechanism. CONSTITUTION:An address conversion mechanism 13 refers to a main memory control table 16 to check whether or not a desired control program exists on a main memory 17.
