Abstract
A data transfer control apparatus includes a channel controller and plural transfer controllers. The channel controller receives, prioritizes and queues data transfer requests. An event to transfer controller table enables recall of a transfer controller number corresponding to the data transfer request. The plural transfer controllers are independent and can operate simultaneously in parallel. Each transfer controller includes a read bus interface and a write bus interface which arbitrate with other bus masters in the case of blocking accesses directed to interfering devices or address ranges.
