Abstract

The invention discloses a cache device based on adaptive routing and scheduling policy. The cache device comprises a controller and an external cache memory component, wherein the controller comprises a speed pre-judging module, input buffer modules I and II, output buffer modules I and II, a routing and scheduling module, a cache memory control module and an SSD control module; and the adaptive routing and scheduling module realizes dynamic routing and storage of a data link by adopting an AOS virtual channel dynamic scheduling protocol. The cache memory component establishes a 'memory bank' by using an external cache memory to expand the data storage depth. In the invention, a three-level data route and a buffer mechanism are established by using the internal second-level buffer of the controller and the external cache memory; and through the dynamic routing and scheduling method, the buffering reuse of a high-speed input / output data channel of the external cache memory component is realized, and the utilization rate of the storage bandwidth of the caching memory component is increased.

Description

technical field [0001] The invention relates to a high-speed cache design method, in particular to a high-speed cache device based on adaptive routing and scheduling strategies. Background technique [0002] With the rapid development of information technology, the amount of information generated globally every year shows explosive growth, and the storage and processing of massive information puts forward very high requirements on the performance of storage systems. Through the application of cache technology, the interface compatibility between the storage system and other systems can be realized, the access speed of the system to data can be improved, and the service life of the storage system can be extended. [0003] At present, most domestic storage system caching technologies use external cache memory ping-pong operations. In applications with high system latency indicators, it is often necessary to configure two caches for storage links and playback links. Due to the...
