Embodiment 1

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0023] A kind of DSP multi-image starting method based on AIS order, comprises the following steps:

[0024] Step 1: automatically load and carry out many mirror image program start-up programs: the mirror image file in the described many mirror image program start-up programs is stored in the initial address space of DSP external memory as the mirror image file of DSP power-on default loading;

[0025] Step 2: Execute the image selection strategy: the multi-image program launcher selects an ...

Abstract

The invention discloses a DSP multi-mirror starting method based on an AIS command, which is used for solving the problem of multi-mirror starting of a DSP digital signal processing system. The technical solution is to use the multi-mirror program startup algorithm to address and select multiple mirror files according to user requirements, and to load them from the external memory into the program memory of the DSP by parsing the AIS command, and execute it automatically. The invention utilizes a multi-mirror program startup algorithm to flexibly and selectively execute a plurality of mirror files, realizes the overloading and switching of DSP programs according to different user requirements, and improves the versatility, adaptability and maintainability of the digital signal processing system .

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to an AIS command-based DSP multi-mirror starting method. Background technique [0002] AIS is the abbreviation of Application Image Script (Application Image Script), which is a special command set for image loading and running. The digital signal processing chip (DSP) usually integrates a program startup module that can receive AIS commands, and completes the application image loading and startup operation when it is powered on. These startup modules usually have a single function, and can only read a unique image from a fixed address for execution, and cannot realize multi-image startup, nor can it perform the function of image storage address addressing. With the development of digital technology and diversified applications, more and more digital signal processing systems require DSP to implement dual mirror or multi-mirror startup, and select the appropriate...
