Abstract

The invention discloses a method for upgrading a DSP program by Ethernet under an FPGA and DSP architecture. The method comprises the following steps: the upper computer generates and sends DSP upgrading information to a FPGA chip, and the FPGA chip stores the obtained DSP upgrading information to a DDR memory corresponding to the FPGA chip; after all DSP upgrading information is stored in the DDR memory, the DSP chip sends a data reading request instruction to the FPGA chip; the FPGA chip responds to a data reading request instruction, and sequentially reads and sends the DSP upgrading information to a storage FLASH of the DSP chip through an FIFO in the FPGA chip; and after all the DSP upgrading information is written into the storage FLASH, the DSP chip is upgraded based on the DSP upgrading information. According to the invention, after the upgrading information in the upper computer is obtained through the FPGA chip based on the Ethernet, the FIFO in the FPGA transmits the upgrading information to the storage FLASH of the DSP chip to carry out online programming upgrading work, and the whole process is automatic and intelligent.

Description

technical field [0001] This application relates to the technical field of online upgrade of programmable devices, in particular, to a method for upgrading DSP programs via Ethernet under the architecture of FPGA and DSP. Background technique [0002] The TMS320C67x series DSP designed by TI is widely used in rocket and other aircraft-related application scenarios. Since this type of DSP does not integrate commonly used serial ports, Ethernet ports, CAN bus and other interfaces, it often expands external devices by adding FPGA chips. The FPGA is responsible for the control of external devices, and the DSP chip implements algorithm control and data analysis. Usually, the upgrade of DSP software needs to open the outer case of the product, and connect to the corresponding JTAG debugging interface of the DSP through a dedicated download cable to perform program programming and upgrading, and the operation is more complicated. Contents of the invention [0003] In order to sol...
