Abstract

An input/output control device includes: a bus connected to an input interface; a plurality of circuit selectors which are connected to the bus and to which validity or invalidity of an operation is set, each circuit selector outputting a signal of the bus when the validity is set; a plurality of logical circuits which are respectively provided to each of the circuit selectors, each logical circuit performing a logical operation when a signal is inputted from the circuit selector; an output selector which is connected to the bus and to which validity or invalidity of an operation is set, the output selector outputting a signal of the bus to an output interface when the validity is set; and an operation part which validates or invalidates the plurality of circuit selectors or the output selector based on an operation order of the plurality of circuit selectors and the output selector.

Dependent claims

An input/output control device comprising:

a bus that is connected to an input interface to which a signal is inputted from outside the input/output control device;
a plurality of circuit selectors that are connected to the bus and to which validity or invalidity of an operation is set, each of the plurality of circuit selectors outputting a signal of the bus when the validity is set but not outputting the signal of the bus when the invalidity is set;
a plurality of logical circuits that are respectively provided to each of the plurality of circuit selectors, each of the plurality of logical circuits performing a logical operation when a signal is inputted from a respective one of the plurality of circuit selectors and outputting a signal representing an operation result to the bus;
an output selector that is connected to the bus and to which validity or invalidity of an operation is set, the output selector outputting a signal of the bus to an output interface when the validity is set but not outputting the signal of the bus to the output interface when the invalidity is set;
and
an operation part to validate or invalidate the plurality of circuit selectors or the output selector, based on an operation order of the plurality of circuit selectors and the output selector.
