Abstract
A system for changing the source and destination devices of data transfers under software control. Default data transfers are made from numbered source devices to the same-numbered destination devices, the data requests being routed through multiplexers which pair, for example, source 1 with destination 1, source 2 with destination 2, etc. The multiplexer control signals originate in a register which is originally loaded with default control bits. However, in real time, the bits within the control register can be re-loaded to provide outputs other than the default values. Then, the data from a source can be directed to any one of the destination devices.
