Abstract
The transfer controller with hub and ports (TCHP) performs the task of communication throughout an entire system in a centralized function. A single hub (435) tied to multiple ports (440, 447, 450, 452) by a central pipeline is the medium for all data communications among DSP clusters (455), external devices, and external memory. A transfer request queue manager (420) receives, prioritizes and queues data transfer requests. Each data port includes an identically configured interior interface (901) connected to the hub (435) and an exterior interface (902) configured for a target external memory/device connected to the port. The interior interfaces of all ports are clocked at a common internal frequency, while the exterior interfaces are clocked at the frequency of the external memory/device connected to the port.
