ABSTRACT:
A cross-bar switch includes a set of input ports for receiving data packets and a set of sink ports coupled to the input ports to accept and forward the data packets. Each sink port includes a multiple entry point FIFO with multiple data inputs for receiving data packets. In one implementation, the multiple entry point FIFO includes a FIFO storage buffer and request logic coupling the multiple entry point FIFO's data inputs to the FIFO storage buffer. The multiple entry point FIFO concurrently maintains separate pointers into the FIFO storage buffer for each data packet being received on the multiple entry point FIFO's data inputs.
