Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] figure 1 It is a structural block diagram of a configuration cache controller system oriented to a coarse-grained reconfigurable processor of the present invention. This structure is composed of configuration cache control logic, configuration cache interface, configuration cache classification table, configuration cache memory, configuration cache lookup table, configuration cache resolver, and configuration entry generator. The configuration cache control logic is used to control the running state of the entire controller; the configuration cache interface is used to analyze the identification of the configuration unit in the configuration block outside the configuration cache controller and read the configuration block information; the configuration cache classification table is used to store configuration units The configuration cache memory is used to stor...

Abstract

The invention discloses a coarse-grained dynamic reconfigurable processor-oriented configuration cache controller. The coarse-grained dynamic reconfigurable processor-oriented configuration cache controller consists of a configuration cache control logic, a configuration cache classification table, a configuration cache memory, a configuration cache lookup table, a configuration cache interface, a configuration cache analyzer and another configuration cache control logic, wherein the components work cooperatively to realize the pre-fetching and updating of configuration units. By utilizing the coarse-grained dynamic reconfigurable processor-oriented configuration cache controller, the time required for reading configuration information by reconfigurable arrays can be effectively decreased, and the performance of coarse-grained dynamic reconfigurable systems can be enhanced.

Description

technical field [0001] The invention relates to the field of computer hardware, in particular to a configuration cache controller for a coarse-grained dynamic reconfigurable processor, which can be applied to the optimization of a coarse-grained dynamic reconfigurable configuration cache structure. Background technique [0002] In current coarse-grained dynamic reconfigurable processors, the configuration information is used to set the computing array of the coarse-grained dynamically reconfigurable processor to realize various functions stipulated in the configuration information, so as to realize functional reconfiguration the goal of. Therefore, the configuration information contains a lot of content, and it takes too long for the calculation array of the coarse-grained dynamically reconfigurable processor to read the configuration information, which reduces the performance of the dynamically reconfigurable processor to a certain extent. In order to improve the performan...
