Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] The DSP chip used in the present invention is TMS320C6678 produced by TI Company, and the NOR FLASH memory used is MT28GU01GAAA2EGC produced by Micron Company.

[0028] The present invention provides a simplified implementation method of multi-core DSP power-on self-starting based on EMIF16, wherein the automatic loading and starting process of the processor means that after the processor is powered on or reset, according to the different loading modes set, The process of automatically loading the executable code stored in the external non-volatile memory into the memory and running the program correctly. Taking TMS320C6678 multi-core DSP as an example, the loading modes mainly include: EMIF16, I2C loading, SPI loading, SRIO loading, PCIe loading, HyperLink, etc.; :1] to select the hardware state at reset. BOOTMODE...

Abstract

The invention relates to a simplified implementation method of multi-core DSP power-on self-start based on EMIF16, belonging to the field of embedded device power-on self-boot technology. Through thethree-stage loading process, the invention modifies the CMD file, stores the multi-core program in sections, and writes the program burning-writing function and the two-stage boot program, so that thecompiling and burning-writing process of the multi-core program can be completed under the same CCS project, and finally correctly realizes the power-on self-startup of the multi-core DSP program. The method disclosed by the invention discards the tedious processing process of the current multi-core DSP power-on self-startup, does not need to compile the multi-core programs separately, omits thestep of manually synthesizing a plurality of image files, and improves the loading efficiency of the multi-core programs. The method of writing burn-write function in engineering is adopted, which makes multi-core program burn-write convenient. The power-on loading process is simple, the program is more readable, the debugging cycle is greatly shortened, and the correct and reliable loading and running of multi-core DSP software can be realized.

Description

technical field [0001] The invention belongs to the technical field of power-on self-guiding of embedded devices, and in particular relates to a simplified implementation method of power-on self-start of multi-core DSP based on EMIF16. Background technique [0002] With the development of signal processing technology and the continuous deepening of research, the combination of DSP and FPGA is generally used to realize signal processing at this stage, in which FPGA is responsible for signal acquisition, AD conversion, and extraction of signal parameters, etc., and DSP realizes the control of main functions, Calculate complex algorithms based on the information obtained by the FPGA, and transmit the calculation results to the display terminal. The multi-core DSP chip integrates multiple cores on one chip. Compared with the previous single-core DSP, it has a qualitative leap in processing speed and capability. Therefore, it is widely used in communication, aerospace, sonar, rad...
