Abstract

The invention discloses a cache replacement method for configuration information of a high-speed reconfigurable processor, and a storage system structure, and the method comprises the steps: updatingan Re value of a hit data block according to a hit frequency when an access is hit, and enabling the Re value to be the priority of the replacement of the data block; and when the access is missing, updating the Re value of the data block replaced into the cache according to the hit frequency, and determining the replaced data block through a windowing selection algorithm. The cache replacement strategy is realized by changing the replaced priorities of the data blocks, so that the cache replacement strategy is convenient to transplant in the existing storage system, and the hardware overheadis low. According to the cache resource allocation method and the device, cache resource allocation is carried out according to the two characteristics of the size and the frequency of the configuration information, the overall missing rate of the cache is reduced instead of only considering the missing rate of a single cache group, and in addition, the cache resource allocation method and devicehave good adaptability to a working set larger than the cache capacity.

Description

technical field [0001] The invention belongs to the technical field of high-speed cache management, and in particular relates to a high-speed reconfigurable processor configuration information cache replacement method and a storage system structure. Background technique [0002] A reconfigurable processor is a parallel computing architecture with both high flexibility and high energy efficiency. The change often only consumes a few or a dozen clock cycles, and then drives the arithmetic unit array to perform calculations through the data flow. While possessing flexibility, performance is gradually approaching dedicated custom chips. The main application areas of reconfigurable processors include media processing, communication baseband processing, encryption and decryption calculations, pattern recognition, etc., which are characterized by intensive calculations and weak dependencies between data. With the continuous development of reconfigurable computing technology, the ...
