Abstract

The invention discloses a reconfigurable processor and a configuration method. The reconfigurable processor comprises a reconfigurable configuration unit and a reconfigurable array; the reconfigurable configuration unit is used for providing reconfiguration information for reconfiguring a computing structure in the reconfigurable array according to an algorithm matched with the current application scene; the reconfigurable array comprises at least two stages of computing arrays, and the reconfigurable array is used for connecting the two adjacent stages of computing arrays into a data path pipeline structure meeting the computing requirements of an algorithm according to the reconfiguration information provided by the reconfigurable configuration unit; and in the same level of computing array, the pipeline depths of different computing modules accessed to the data path pipeline structure are equal, so that the different computing modules accessed to the data path pipeline structure synchronously output data. Therefore, the reconfigurable processor can configure adaptive assembly line depth according to different algorithms, and on this basis, the overall streamline of the data processing operation of the reconfigurable array is realized, and the data throughput rate of the reconfigurable processor is improved.
