FPGA (field-programmable gate array) program upgrading and online downloading method in digital signal processing platform

Abstract

The invention provides an FPGA (field-programmable gate array) program upgrading and online downloading method in a digital signal processing platform. The FPGA program upgrading and online downloading method includes two parts of hardware and software, wherein the hardware comprises an X86 architecture module, a communication bus, FPGAs, a PROM (programmable read only memory), functional interfaces and a power supply, wherein the X86 architecture module is connected with the FPGAs through the communication bus, the FPGAs are simultaneously connected with the PROM through special circuit interfaces of the FPGAs, the other functional interfaces of the FPGAs constitute the functional interfaces, and the whole system adopts the power supply for supplying power; and the software mainly comprises programs in an upper computer and the FPGAs in the X86 architecture module, so that human-computer interaction control, upgrading, online downloading and checking of the programs of the FPGAs and the like are realized. According to the method provided by the invention, the characteristics of digital signal processing platforms in the fields of software radio, satellite communication and the like are fully combined to perform program upgrading and updating of the FPGAs, then the programs of the FPGAs are convenient and easy to update and upgrade, the time required for disassembling and assembling products, utilizing a special downloading wire to download and performing other processes can be greatly saved, the design cost is saved, the complexity in design is reduced, and the workload in design is also reduced.

Description

technical field [0001] The invention belongs to the technical field of FPGA. Specifically relates to an FPGA program upgrade online download method in a digital signal processing platform. Background technique [0002] With the advancement of technology, FPGA has developed rapidly, whether it is in the field of satellite communication and ground communication, or in the field of automatic control, FPGA has been widely used. Because of the programmable characteristics of FPGA, it provides a convenient door for product upgrading, especially in the field of digital signal processing in the field of software radio, whether it can be easily upgraded on site and whether it can be used flexibly is a key factor. Currently, the FPGAs used in digital signal processing platforms in the software radio field are mainly mid-to-high-end FPGAs from companies such as Xilinx and Altera. These FPGAs have many logic units, many built-in DSP modules, and high speed, which are suitable for high-...
