Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] At present, each DSP board needs to develop a dedicated application program when the board is tested, and only one program can be loaded and executed after the system is powered on. To execute another application program, the old program can only be overwritten by the new program. For multi-model series products that use DSP equipment to test similar functions, usually multip...

Abstract

The invention provides a testing device based on a DSP board card and a testing method thereof. Firstly, when power is supplied, the upper 5-bit address line of an EMIF bus of a DSP 6713 chip is expanded by an FPGA and is set to 0 by default, and at this time, a monitoring program is loaded by a minimum unit of the DSP by default. Secondly, the host computer and the monitor carry out code matching, and judge whether the code matching is successful or not. If the code matching is successful, the monitor program is executed, and the configuration information is modified by the host computer. Ifthe code matching is failed, the monitor program reads the configuration information, executes the selected application program, and finally, the program is terminated and the power is cut off. The technical scheme realizes the selective loading of multi-application programs, improves the efficiency of DSP board test and saves the cost of DSP board test for multi-model series products with similarfunctions tested by DSP equipment.

Description

technical field [0001] The invention relates to the technical field of DSP board testing, in particular to a testing device based on a DSP board and a testing method thereof. Background technique [0002] At present, DSP board testing is a basic step for product launch. During the process of implementing DSP board testing, the inventors found that there are at least the following problems in the prior art: DSP application development belongs to custom program development, and each DSP board needs to be developed. application program, only one program can be loaded and executed after the system is powered on. To execute another application program, the old program can only be overwritten by the new program. For multi-model series products that use DSP equipment to test similar functions, usually multiple test boards filled with a single application program are used interchangeably, which is difficult to achieve efficient testing, and the testing cost is high.
