On-line reconfiguration system and method based on FPGA

Abstract

The invention discloses an on-line reconfiguration system and method based on an FPGA. The method is achieved mainly through the FPGA. A standard communication interface module, a memory control module, a high-performance embedded processor core, a reconfiguration function module, a reconfiguration control module and an output interface control module are achieved in the FPGA. A high-performance processor embedded into the FPGA is used for being in communication with an upper computer, locally and dynamically configuring the reconfiguration module in the FPGA and transmitting corresponding data to the reconfiguration hardware function module according to different hardware functions, and processed data are output to a peripheral interface unit through the output interface control module. By adopting the on-line reconfiguration system and method based on the FPGA, time division multiplexing of various hardware function modules with different functions can be achieved, the utilization ratio of resources in the FPGA of an embedded processing system is improved, and complex hardware function circuits can be achieved through less hardware resources.

Description

technical field [0001] The invention belongs to the embedded processing system design technology, in particular to an FPGA-based online reconfiguration system and method. Background technique [0002] In the embedded processing system, it is required that the system must have the ability to process a large amount of data within a predetermined time, so as to ensure the real-time performance of the system. At the same time, embedded processing technology also has strict requirements on the volume, power consumption and stability of the system. FPGA has been widely used in embedded processing because of its remarkable characteristics of high integration, high speed and high reliability. [0003] Since the hardware function modules of the embedded processing system have a large amount of data to be processed by the system when they are implemented, the amount of modules is generally relatively large when using FPGA to realize the hardware function modules. At the same time, t...
