ABSTRACT:
A matrix type bus connection system comprising a plurality of master devices and slave devices, wherein data transfer between arbitrary master device and slave device is available, and the power reduction method therefor is disclosed. When a slave device is to be setting to low-power operation state, decoding table contents of relevant master device are altered according to the control signal from a low-power control circuit, first of all, then connection request for the destination device is set from the slave device to be in low-power operation state to the predetermined default slave device. After that, the target slave device to be in low-power operation is set to be in low-power operation state by the low-power control signal from the low-power control circuit.
