Abstract

The invention discloses an FPGA and DSP program upgrade and online reconfiguration system and method. The system includes a USB external interface for connecting external upgrade devices, a FLASH chip for storing upgrade programs imported by the USB external device, including a DSP processor upgrade program and an FPGA upgrade program, and a DSP processor for taking the upgrade programs out from an FLASH chip and sending the programs to an FPGA processor for upgrade. By adopting the FPGA and DSP program upgrade and online reconfiguration system and method, the problem that target board upgrade program operation is complicated is solved, the number of storage devices in the system is decreased, and the hardware cost is reduced.

Description

technical field [0001] The invention relates to an FPGA upgrading technology, in particular to an FPGA and DSP program upgrading and online reconfiguration system system method. Background technique [0002] At present, the upgrade of DSP program is mainly through emulator programming upgrade and UART serial port programming upgrade. To use the emulator to program and upgrade, you must first open the cover of the product, then connect the emulator to the JTAG interface of the DSP, and use professional technicians to complete the upgrade on the computer equipped with the emulator driver and CCS application software. Using this method in the field to upgrade the program steps is complicated, and requires relevant professional and technical personnel to operate. UART serial programming upgrade method is simpler than emulator programming upgrade, but still needs to use the host computer to operate, and the data transmission speed is slow. [0003] At present, most FPGA program...
