Abstract

The invention discloses an ID management unit for cache space of network data packages, pertaining to the technical field of network data processing. The ID management unit comprises a component request pre-processing module, a BID application request FIFO module, a BID release request FIFO module, a BID application request pre-processing module, a BID release request processing module, an application BID read interface control module, a release BID write interface control module, an application answering distribution module and a release answering distribution module. The ID management unit for cache space of network data packages has following beneficial effects: in the way that the ID management unit is combined with the theory of parallelly considering priorities and an FIFO storage mechanism and a cross-connect mode are adopted, BID application and BID release are executed parallely so that processing speed is increased; ID derangement of the cache space of a network processing unit and highly-efficient management are achieved; and the problem of bandwidth bottleneck in the network processing unit is obviously improved.

Description

technical field [0001] The invention discloses a network data packet cache space ID management unit, which belongs to the technical field of network lock data processing. Background technique [0002] With the rapid development of the Internet, the Internet has entered thousands of households, and people's lives are increasingly inseparable from the Internet. The emergence of the network has brought indescribable convenience to people's life. At the same time, people have put forward higher and higher requirements for the network data processing speed. The dedicated network processor ASIC chip has gradually replaced the traditional network data processing structure. With the further improvement of people's requirements for network processing performance, the processing bandwidth of network processors is continuously increasing, and the processing speed is also continuously improving, and an efficient and fast cache management mechanism is required. Due to the low storage re...
