Microprocessor apparatus for data exchange

PCT No. PCT/SU79/00117 Sec. 371 Date Jun. 8, 1981 Sec. 102(e) Date Jun. 8, 1981 PCT Filed Nov. 28, 1979 PCT Pub. No. WO81/01622 PCT Pub. Date Jun. 11, 1981.Microprocessor apparatus for data exchange is controlled by information supplied via a microinstruction bus and a triggering line and transmits data from some external bidirectional data buses to other such buses. Data is supplied via data exchange units (11, 12, 2), internal bidirectional data buses and a switch. In addition to the transmission of information, the microprocessor apparatus can, depending on the code of the microinstruction, count the number of transmitted words via a counter and compare or mask data or arbitrate transmitted data via a data processing/converting unit. While executing microinstructions, the counter, the data processing unit, a register unit and a switch shape distinguishing features of the processed information, to be later fed to a conditional operation unit. The conditional operation unit shapes a generalized condition for readjustment of operation of a control unit.
