Problems solved by technology

And using JTAG to load, not only requires additional tools such as emulators and development platforms, but also requires professionals to operate, and the scope of application is narrow
[0005] In the 8th issue of "World Electronic Components" in 2008, in the article "Realization of DSP Program Loading Based on Computer Serial Port" by Li Shijie and others of Air-to-Air Missile Research Institute, a method of loading DSP based on computer serial port is mentioned. A UART chip is connected to the multi-channel buffered serial port (McBSP) of the DSP after performing level conversion, but the communication protocol is simple, and the given example only involves the case of a single program module of the DSP, and cannot Suitable for complex image processing machines
And the reliability of this loading method is not high, if the loading is wr

Embodiment Construction

[0051] Further details will be given below in conjunction with the accompanying drawings and embodiments.

[0052] figure 1 The flow of the loading method of the present invention is given, specifically.

[0053] (1) Convert the loader executable file compiled by the DSP development platform into a pure data file supported by FLASH, for example, convert the .out file compiled by CCS (Code Composer Studio) into a hexadecimal .hex file . The loading program includes a FLASH loading submodule, a switching program submodule, a path detection submodule, a device testing submodule and a FLASH data viewing submodule.

[0054] (2) Adopt emulator and debugging interface provided by DSP manufacturer, for example, adopt USB emulator and JTAG port of TI company, write the data file generated in step (1) to the first address of DSP off-chip FLASH.

[0055] (3) Starting the loading and testing device, including connecting the loading and testing device with the image processor to be load...

Abstract

The invention discloses a method and a device for loading and measuring data of an image processing device, which is characterized in that loading programs are stored in a first address of a flash; during loading and starting, a DSP transfers a loading program module to a memory; a plurality of image processing programs to be loaded are stored in a successive address of the flash; and the DSP switches between the loading programs and the plurality of image processing programs according to received instruction information so as to finish flash data loading, channel testing and other testing tasks. After the image processing device is encapsulated, the invention updates and maintains the programs, enables different image processing programs according to different target types and is convenient in operation and high in reliability.

Description

technical field [0001] The invention belongs to the application field of digital image processing, and in particular relates to a method and a device for loading data into an image processing machine. Background technique [0002] An image processor is a device that performs a series of operations such as processing, analysis, identification, and tracking on an input image to obtain useful information. Digital Signal Processing (DSP) is one of the main carriers for the operation of the image processor system. When the DSP is running, its programs and data are generally stored in the internal DSP or the externally expanded Static Random Access Memory (SRAM), and will be lost after power failure. Therefore, the program files and some data files of the DSP need to be solidified to an external non-volatile memory, such as flash memory (FLASH). [0003] The image processor needs to use different image processing algorithms, different working parameters and template images for s...
