Embodiment Construction
[0018] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0019] refer to figure 1 Shown, one embodiment of the present invention is a kind of interface extensible programming programming method based on DSP platform, described method comprises and preferably operates according to the following steps:
[0020] Step S1, after the previous loading of the DSP program is completed, the initialization is performed again;
[0021] Step S2, the host computer reads the program file to be programmed, and transmits the program file to the DSP program;
[0022] Step S3, after the DSP program receives the program file from the host computer, store it in the specified FLASH chip address range, then copy the content of the program file in the FLASH chip to the memory, and use the program to jump The transfer instruction points the PC pointer to the cin00 program entry address in the program file, thereby completing the reloading of the ...

The invention discloses an interface extensible programming method based on a DSP platform, and belongs to a programming method. The interface extensible programming method is characterized by comprising the following steps that firstly, initialization is carried out again after a DSP program is loaded last time; secondly, an upper computer reads a program file needing to be programmed, and transmits the program file to a DSP program; thirdly, after receiving the program file from the upper computer, the DSP program stores the program file in an appointed FLASH chip address section. By the adoption of an extensible programming interface, custom-made selection can be carried out according to the demands of customers, programming can be finished only through the data interface of the DSP system, the DSP programming is effectively accelerated, the programming process can be controlled, meanwhile, problems occurring in the programming process can be fed back to the upper computer in time, the operation is easy, a programming result is reliable, the interface extensible programming method can be used for programming program file contents of various DSP devices in the process of updating, and the application range is wide.
Description
technical field [0001] The present invention relates to a method for program programming, more specifically, the present invention mainly relates to a method for program programming based on a DSP platform with extensible interface. Background technique [0002] At present, the upgrade method of DSP embedded equipment is mainly through the traditional program upgrade method, and the program burner tool provided by TI company is used to burn the program with the JTAG emulator. This method is a general programming method, but for some special occasions, such as the JTAG port is not drawn out in mature embedded products, or the embedded device is inconvenient to connect to the JTAG port in a closed box, the aforementioned traditional upgrade method brings It caused great inconvenience and could not meet user needs. To put it simply, the aforementioned programming method mainly has the following problems: one is that the programming interface is single, and only the JTAG port c...
