u00fcbertragungsteuerung with hubs and torachitektur

摘要

The transfer controller includes a single hub (435) connected to multiple ports (440,447,450,452) by a central pipeline, feeding all commands between digital signal processor clusters (455), while the hub engine (435) performs servicing of transfers and breaks them into smaller transfers that the devices can handle. An internal memory port mode master (450) interfaces to the data transfer bus (455), connecting the ports to the processor nodes and the external ports interfaces act as a buffer between the hub engine and the external memory or peripheral port. An independent claim is included for a data processing system.
