Reconfigurable configuration information cache system based on block matching and compression method

Abstract

The invention discloses a reconfigurable configuration information cache system based on block matching. The reconfigurable configuration information cache system based on block matching comprises a configuration information analysis unit, a configuration information compression unit, a configuration information cache unit and a configuration information decompression unit, wherein the configuration information cache unit comprises an L1-layer configuration information cache and a plurality of L2-layer configuration information caches, the L1-layer configuration information cache is used for storing sharing configuration information of multiple reconfigurable arrays, and each L2-layer configuration information cache corresponds to one reconfigurable array and is used for storing local configuration information of the reconfigurable array. By the adoption of the reconfigurable configuration information cache system based on block matching and a compression method, the resource utilization rate of configuration information caches in a coarse dynamic reconfigurable system is increased, more configuration information can be stored under the condition that the capacity of the configuration information caches is not changed, and hardware expenditure of the coarse dynamic reconfigurable system is reduced.

In order to adapt to the high complexity of software applications, the number of task reconfigurations in reconfigurable systems has increased significantly, which has resulted in longer reconfiguration times for reconfigurable systems

At the same time, in order to meet the high computing performance requirements of software applications, the computing resources of the reconfigurable system increase, and the computing time is reduced by increasing the parallelism of hardware execution. However, this greatly increases the amount of configuration information required for computing resource reconfiguration. , which further increases the reconfiguration time of the reconfigurable system, making the performance improvement of the reconfigurable system encounter a bottleneck
