Abstract

The invention provides a configuration loading system and method for a reconfigurable processor, and the system comprises a configuration controller which is used for obtaining the length of configuration data needed by a configuration task of a PEA and a plurality of configuration addresses; acquiring a plurality of configuration packets and sending the configuration packets to the PEA controlleruntil the number of the currently acquired configuration packets is equal to the length of the configuration data; judging whether a PEACPFinish signal is received or not at present, and if so, pre-fetching configuration data of a next configuration task; a PEA controller used for analyzing the top-layer configuration information from each configuration packet, determining the corresponding PE and sending the PE; after PE_CP_Finish signals sent by all PEs of the current configuration task are received, sending PEA_CP_Finish signals; and a PE used for sending PE_CP_Finish signals after one configuration packet is executed each time. According to the invention, the configuration of the reconfigurable processor can be loaded, and the delay is less.

Description

technical field [0001] The invention relates to the technical field of computer hardware, in particular to a configuration loading system and method for a reconfigurable processor. Background technique [0002] A reconfigurable processor is a new type of processor architecture. Its hardware functions can be dynamically configured, but it also increases the configuration delay while its versatility is better than that of a dedicated processor. [0003] Therefore, there is currently a need for a configuration loading scheme for a reconfigurable processor with less delay. Contents of the invention [0004] The embodiment of the present invention proposes a reconfigurable processor configuration loading system, which is used to load the configuration of the reconfigurable processor with less delay. The system includes: [0005] Configuring a controller and a processing unit array PEA, wherein the PEA includes a PEA controller and a plurality of processing units PE; [0006] ...
