QUEUE MANAGER FOR BUFFER

摘要

PURPOSE: A queue manager for buffer is provided to provide a bandwidth maintenance queue manager for (first-in first-out)FIFO buffer provided with another DRAM storage device for maintaining a FIFO queue. CONSTITUTION: A FIFO buffer is used on an ASIC chip so that plural queue entries can be stored and retrieved. As long as the total size of queues does not exceed a usable storage device in the buffer, any data storage device is not required more. When supplied data exceeds the buffer storage space of a certain prescribed quantity in the FIFO buffer, however, these data are written in the other data storage device in the form of packet and read from that storage device. That packet has an optimal size for maintaining the peak performance of the data storage device and is written in the data storage device in a way such as queuing with the address sequence of FIFO.
