Abstract

A method and a system for realizing automatic tests of a Digital Signal Processor (DSP) are provided. The method comprises: constructing a test platform, and realizing the communication between an algorithm simulation module (41) and a DSP development module (42) through running a unified script in the test platform (501); generating a test case through the test platform controlling the algorithm simulation module (41) to run an algorithm simulation project (502); and controlling the DSP development module (42) to run the DSP project corresponding to the algorithm simulation project and perform the test case, and obtaining the test result for the DSP project (503). The method and the system for realizing automatic tests of a DSP provided by the solution unite algorithm simulation software and a DSP development tool to perform automation simulation tests for the DSP project, and realize real-time generation of test data, automatic comparison of test results and automatic generation of a test report. The solution increases the automation level of the DSP test, saves the manpower cost and improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of digital signal processors, in particular to a method and system for realizing automatic testing of digital signal processors. Background technique [0002] A digital signal processor (Digital Signal Processor, DSP for short) is a microprocessor with a special structure. The DSP chip uses a Harvard structure that separates programs and data, has a dedicated hardware multiplier, and uses pipeline operations extensively to provide special DSP instructions can be used to quickly implement various digital signal processing algorithms. As a programmable special-purpose chip developed rapidly in recent years, DSP chip is an important technical tool in the practical process of digital signal processing theory. Due to the excellent digital signal processing capability of DSP, it has been widely used in the baseband digital signal processing part. In the baseband processing part of wireless communication equipment...
