MULTI-PORT SYSTEM FOR COMMUNICATION BETWEEN PROCESSING ELEMENTS

An aspect of the invention relates to communication between a first processing element and a second processing element. A first-in-first-out circuit (FIFO) includes a data input port, a data output port, an object-sent port, an object-end port, a memory, and control logic. The data input port is coupled to the first processing element. The data output port is coupled to the second processing element. The object-sent port is configured to receive an object-sent signal from the first processing element. The object-end port is configured to send an object-end signal to the second processing element. The memory is configured to store objects, each of the objects include a plurality of data words. The control logic is configured to control reading and writing to the memory, processing the object sent signal, and generating the object end signal.
