Abstract

PURPOSE:To contrive improvement of operation processing capacities and reduction in processing times, by installing an exclusive input/output port having an assembled- in accumulator. CONSTITUTION:Operation results contained in an accumulator 11 of an exclusive input/output port 10 are sent to another accumulator 12 or directly output to the outside. Moreover, at the port 10, operations of the same sequence are performed. The processing time can be reduced by informing completions of operations at the port 10 through a interruption input signal while the accumulator 12 is executing other operations.
