ABSTRACT:
An apparatus and method for transferring data among clients of a time division multiplexed network is provided. In one aspect of the preset invention the apparatus includes clock circuits that allow for a variable number of time slots and a variable bus cycle of the network. In another aspect of the present invention a network interface module includes an indirection register that contains relationships between memory storage locations and channels of a time domain multiplexed network. In yet another aspect of the present invention, a network interface module is provided that comprises a memory, and first and second registers. In one mode of operation of the network interface module, data from the memory for a client is pre-fetched from the memory, prior to the start of a bus cycle and is stored in the registers to minimize memory access delays in the system.
