Abstract
A system and method for controlling the flow of messages transferred between modules of a computer system is disclosed. The system includes a receiver module comprising a buffer having a capacity to store a predetermined number of messages, and a transmitter module coupled to the receiver module. The transmitter module includes a counter for maintaining a count value representative of free space in the buffer. The transmitter module transmits a message to the buffer when the count value is greater than zero. Then, the transmitter module decrements the count value by a value characteristic of the transmitted message, such that the count value is updated to be representative of free space in the buffer after transmission of the message to the buffer.
