Abstract

The invention discloses an online program upgrading method and an online program upgrading system based on DSP+FPGA. The online program upgrading method comprises the steps that: upper computer supporting software analyzes DSP online upgrading firmware information and sends online upgrading data and an online upgrading instruction to an FPGA according to a preset communication protocol, and the FPGA transmits the online upgrading data and the online upgrading instruction to a DSP through FIFO; the DSP reads and analyzes cache data of the FIFO, and caches the analyzed online upgrading data in areadable-writable storage unit; and the DSP acquires the upgrading data of the readable-writable storage unit according to the analyzed online upgrading instruction so as to realize the online upgrading operation of the hardware equipment to be upgraded. Therefore, the program running speed is improved, the DSP resources are saved, and the program upgrading accuracy and reliability are guaranteed.

Description

Technical field [0001] The invention belongs to the field of DSP program online upgrade, and specifically relates to a DSP+FPGA-based program online upgrade method and system. Background technique [0002] At present, DSP (Digital Signal Processor) is a digital signal processor. The DSP chip uses a Harvard structure that separates programs and data. It has a dedicated hardware multiplier, widely uses pipeline operations, and provides special DSP instructions that can be used for fast Realize various digital signal processing algorithms. FPGA (Field Programmable GateArray) is a kind of semi-custom circuit in application specific integrated circuits. It is a programmable logic array with abundant logic resources, repeatable programming, and high integration. Due to the advantages of FPGA chips in the processing of low-level algorithms with large amounts of data and the advantages of DSP chips in the processing of complex algorithms, the application of DSP+FPGA real-time signal pro...
