Abstract
A buffer management subsystem receives data from one or more source processes for transfer to one or more destination processes. The buffer management subsystem includes a buffer memory and a buffer pointer FIFO that associated with one of the destination process. The buffer pointer FIFO stores pointers to buffers in the buffer memory which are available to be used to store data from the source process(es) for transfer to the respective associated destination process. When data is received from a source process for transfer to a destination process, a buffer pointer is retrieved from the buffer pointer FIFO associated with the destination process and used in storing the data in the buffer pointed to by the buffer pointer. When the data is retrieved from the buffer for transfer to the destination process, the buffer pointer to the buffer is returned to the buffer pointer FIFO.
