System for updating FPGA (Field Programmable Gate Array) configuration program from a long distance based on control of processor and method therefor

Abstract

The invention discloses a system for updating an FPGA (Field Programmable Gate Array) configuration program from a long distance based on the control of a processor and a method for updating the FPGA configuration program from a long distance based on the control of the processor. The system comprises a processor module, an FPGA module, an SPI (Serial Peripheral Interface) memory module and a buffer module, wherein the processor module is connected with the SPI memory module and is connected with a communication interface, the SPI memory module is connected with the FPGA module, and the processor module is connected with the SPI memory module by the buffer module. When the configuration program of an FPGA requires to be updated, an upper computer or a terminal downloads the FPGA configuration program into the SPI memory module through the communication interface and the processor module, and the FPGA module can automatically load the configuration program memorized in the SPI memory module in a MasterSPI mode. According to the system and the method, the FPGA configuration program is updated from a long distance, the function of updating the configuration program on line under the non-outage situation is realized, and therefore, the system and the method are particularly suitable for on-site application.

Description

technical field [0001] The invention relates to an FPGA configuration system and method thereof, in particular to a processor-based remote update FPGA configuration program system and implementation method. Background technique [0002] Programmable logic devices are widely used in the R&D and design of today's electronic products. In particular, FPGA (Field Programmable Gate Array, Field Programmable Logic Array) has replaced dedicated IC chips in many product design occasions. The advantage of FPGA lies in ultra-high speed, abundant logic resources, and logic functions that can be flexibly configured by users. It is suitable for occasions where logic interface functions are diverse and flexible. Most FPGAs are based on the SRAM structure, and the configuration program is stored in the SRAM (Static RAM) unit when it works normally. The SRAM unit is usually also called the configuration storage unit (Configuration RAM). Due to the power-off data loss characteristic of the ...
