Abstract:
A cache structure for use in implementing reconfigurable system configuration information storage, comprises: layered configuration information cache units: for use in caching configuration information that may be used by a certain or several reconfigurable arrays within a period of time; an off-chip memory interface module: for use in establishing communication; a configuration management unit: for use in managing a reconfiguration process of the reconfigurable arrays, in mapping each subtask in an algorithm application to a certain reconfigurable array, thus the reconfigurable array will, on the basis of the mapped subtask, load the corresponding configuration information to complete a function reconfiguration for the reconfigurable array. This increases the utilization efficiency of configuration information caches. Also provided is a method for managing the reconfigurable system configuration information caches, employing a mixed priority cache update method, and changing a mode for managing the configuration information caches in a conventional reconfigurable system, thus increasing the dynamic reconfiguration efficiency in a complex reconfigurable system.
