FIELD: information technologies.
SUBSTANCE: situations are possible in processor, when commands and certain parts of program may be arranged in data cash until completion of program. Hardware and software methods are proposed to select command in data cash after miss occurs in cash of commands, making it possible to improve processor characteristic. If command is not available in cash of commands, then address of command access is sent as address of data access into data cash. If there are existing data present in data cash by introduced address of command access, then this data is actually a command, and record of data cash is withdrawn and delivered as command into processor complex. Additional bit may be included into table of command pages to indicate miss in cash of commands, and to specify that data cash shall be checked for availability of command.
EFFECT: expansion of functional capabilities.
