Abstract
A method and apparatus are provided for implementing multiple configurable sub-busses of a point-to-point bus. Each of a plurality of bus interconnects include a transmit interface and a receive interface connected to the point-to-point bus. Each transmit interface includes a transmit buffer and a serializer coupled between the buffer and the point-to-point bus. The transmit buffer provides an asynchronous interface between a transmit source and the serializer. The serializer receives data and control signals from the transmit buffer at a first frequency and transmits data and control signals over the point-to-point bus at a higher second frequency. Transmit steering logic is coupled between the transmit source and each transmit buffer of the plurality of bus interconnects. Transmit steering logic directs data and control signals from transmit source to each selected one of the transmit buffers based upon a selected bus configuration.
