ABSTRACT:
A data processor has a block-multiplexed system channel coupled to a processing engine and a byte-multiplexed bus coupled to multiple I/O devices. A multi-buffer adapter transfers data by cycle-steal (direct memory access) operations between the channel and the bus. The adapter has multiple buffers switchable to the channel in a burst mode by a channel interface and to the bus in a byte mode by a device-level interface.
