High-speed dequeuing of buffer IDS in frame storing system
Abstract:
Incoming frame data is stored in a plurality of dual linked lists of buffers in a pipelined memory. The dual linked lists of buffers are maintained by a link manager. The link manager maintains, for each dual linked list of buffers, a first head pointer, a second head pointer, a first tail pointer, a second tail pointer, a head pointer active bit, and a tail pointer active bit. The first head and tail pointers are used to maintain the first linked list of the dual linked list. The second head and tail pointers are used to maintain the second linked list of the dual linked list. Due to the pipelined nature of the memory, the dual linked list system can be popped to supply dequeued values at a sustained rate of more than one value per the read access latency time of the pipelined memory.
