US Patent 11782679 Multiplexing between different processing channels

A circuit for use in a processor includes a first processing channel having a first logic unit, a second processing channel having a second logic unit, and multiplexing circuitry. The multiplexing circuitry includes an input multiplexer arranged to switch between a first state in which an input of the first logic unit is coupled to an input line of the first processing channel, and a respective second state in which the input of the first logic unit is instead coupled to an input line of the second processing channel; and an output multiplexer arranged to switch between a first state in which an output line of the second processing channel is coupled to an output of the second logic unit, and a second state in which the output line of the second processing channel is instead coupled to an output of the first logic unit.
