Embodiment Construction

[0015] The curing method of DSP program of the present invention specifically comprises the following steps:

[0016] Step 1. Load the executable file code of the DSP target project into the RAM of the DSP through the emulator, and then use the emulator to also load the executable file code of the DSP programming code project into the RAM of the DSP; wherein the DSP target project The executable file code and the executable file code of the DSP programming code project are respectively stored in different spaces of the RAM.

[0017] Step 2. Run the executable file code of the DSP programming code project, split the executable file code of the target project in RAM and write it to the external non-volatile memory.

[0018] Most DSP processors will automatically load the target code from the external non-volatile memory to RAM for execution after power-on. The so-called loading is actually copying and splicing the code of the external memory and placing it in RAM to run. In gen...

Abstract

The invention relates to the field of program solidification, and discloses a solidifying method of a DSP (digital signal processor) program. The solidifying method specifically contains the following steps of: step 1, leading an executable file code of a DSP target project to be loaded in an RAM (random access memory) of a DSP through an emulator, and then using the emulator to load the executable file code of a DSP burning writing code project in the RAM of the DSP, wherein the executable file code of the DSP target project and the executable file code of the DSP burning writing code project are respectively stored in different spaces of the RAM; and step 2, operating the executable file code of the DSP burning writing code project, and splitting and writing the executable file code of a target project in the RAM to an external nonvolatile storage. The method not only can be used for completing solidification of a DSP object code, but also has the advantages of simple realization process, high safety, good reliability, good portability, and does not need format conversion and the like; and the DSP object code can be quickly, universally and reliably solidified and complicated solidifying steps are abandoned through the method provided by the invention.

Description

technical field [0001] The invention relates to the technical field of program solidification, in particular to a method for solidifying a DSP program. Background technique [0002] In an embedded DSP system, the DSP will eventually run off-line without the debugging environment of the host computer, that is, the object code needs to be loaded automatically after the system is powered on. Therefore, it is necessary to place its target code in an external non-volatile memory, such as traditional EPROM, EEPROM, NOR FLASH, etc., and load it into the DSP processor or external RAM to run when the system is powered on. [0003] The executable file output by the DSP target project is in COFF format, the file extension is .out, and the full name is Common Object File Format. The file format includes segment header, executable code and initialization data, relocatable information, line Number entry, symbol table, string table, etc. However, most memories do not support this format a...
