Method and device for generating configuration information of dynamic reconfigurable processor

Abstract

The invention discloses a method and device for generating configuration information of a dynamic reconfigurable processor, and a processor configuring device. The dynamic reconfigurable processor is composed of processing unit arrays, and each processing unit array comprises a plurality of processing units. The method includes the steps of reading information of a task to be executed, generating a top layer of array configuration information of the processing unit arrays according to the information, generating multiple pieces of processing unit configuration information corresponding to the multiple processing units, and assembling the top layer of the array configuration information and the multiple pieces of processing unit configuration information to generate configuration information of the dynamic reconfigurable processor. According to the method, each processing unit has its own independent configuration information, only the processing units where configuration switching is needed are configured when the arrays are configured, the other processing units keep unchanged in the configuration, and therefore the processing units are prevented from being repeatedly configured, partial configuration and selective configuration are achieved, and flexibility of configuration is improved.

Description

technical field [0001] The invention relates to the technical field of processors, in particular to a method and device for generating configuration information of a dynamically reconfigurable processor and a processor configuration device. Background technique [0002] Dynamic reconfigurable processor is a new processor architecture, which has significant advantages over previous single-core processors, dedicated chips, and field programmable logic arrays, and is a direction for the development of future circuit structures. [0003] First of all, a dynamically reconfigurable processor often contains multiple arithmetic logic units, and the number is huge, which is called a many-core array. The array is equipped with a highly flexible routing unit to realize the diversified interconnection between the arithmetic and logic units. Therefore, the many-core array connected by the routing unit can realize high-speed processing of data streams, and has a huge advantage in perform...

AI Technical Summary

Problems solved by technology

[0006] 1) There is often a problem with a large amount of configuration information in configuration technology, which will lead to a corresponding extension of configuration time and an increase in the demand for configuration memory capacity;

[0007] 2) Due to the frequent switching of configuration information in the dynamic reconfigurable processor, it will inevitably increase the configuration power consumption;

[0008] 3) When configuring a reconfigurable processor array, as long as the function of one of the processing units changes, the entire array will need to be reconfigured, and the configuration of a single processing unit cannot be switched while the configuration of other processing units remains unchanged , which involves a lot of repetition and blind configuration
