Method and System for Optimizing Buffer Reservation and Utilization

Abstract

A system for controlling memory buffer reservation comprising a transmitter, a receiver and buffer control logic is provided. The transmitter is configured to transmit a plurality of memory requests on two or more request channels, the plurality of memory requests comprising at least one priority request transmitted on a first request channel. The receiver comprises a plurality of buffers, each buffer having an associated credit, wherein each request channel is provided with a credit value based on the number of buffers allocated to receive memory requests from the corresponding request channel, where at least one credit is provided to the first request channel. The buffer control logic enables the first request channel to use a buffer allocated to a second request channel by utilizing a credit provided to the second request channel for transmitting the priority request to the receiver when a credit provided to first request channel is unavailable.
