Description

实现数字信号处理器自动测试的方法及***  Method and system for realizing automatic test of digital signal processor
技术领域 Technical field
本发明涉及数字信号处理器技术领域， 尤其涉及实现数字信号处理器自 动测试的方法及***。  The present invention relates to the field of digital signal processor technologies, and more particularly to a method and system for implementing automatic testing of a digital signal processor.
背景技术 Background technique
数字信号处理器 (Digital Signal Processor, 简称 DSP)是一种具有特殊结 构的微处理器， DSP芯片内部釆用程序和数据分开的哈佛结构， 具有专门的 硬件乘法器， 广泛釆用流水线操作， 提供特殊的 DSP指令， 可以用来快速地 实现各种数字信号处理算法。 DSP芯片作为近年来迅速发展的可编程专用芯 片， 是数字信号处理理论实用化过程的重要技术工具。 由于 DSP出色的数字 信号处理能力， 在基带数字信号处理部分得到了广泛的应用， 在无线通信设 备的基带处理部分主要釆用数字电路实现物理层协议和相关的数字信号处理 算法。  The Digital Signal Processor (DSP) is a microprocessor with a special structure. The Harvard structure with separate programs and data is used inside the DSP chip. It has a dedicated hardware multiplier and is widely used in pipeline operations. Special DSP instructions can be used to quickly implement various digital signal processing algorithms. As a programmable special chip that has been rapidly developed in recent years, DSP chip is an important technical tool for the practical process of digital signal processing theory. Due to the excellent digital signal processing capability of the DSP, it has been widely used in the baseband digital signal processing part. In the baseband processing part of the wireless communication device, the digital layer is mainly used to implement the physical layer protocol and the related digital signal processing algorithm.
DSP处理***的一般设计流程是： 第一步，根据应用***确定性能指标、 信号处理要求。 第二步， 根据***的要求用高级语言进行算法模拟， 并将算 法模拟的相关数据保存作为 DSP测试验证的依据。 第三步， DSP***软硬件 ***设计。 第四步是调试及测试， 比较实时结果和模拟结果。  The general design flow of the DSP processing system is: The first step is to determine performance indicators and signal processing requirements based on the application system. In the second step, the algorithm is simulated in a high-level language according to the requirements of the system, and the relevant data of the algorithm simulation is saved as the basis for DSP test verification. The third step is the DSP system software and hardware system design. The fourth step is debugging and testing, comparing real-time results with simulation results.
目前对于 DSP的仿真测试， 主要有以下 3种方式：  At present, there are three main methods for the simulation test of DSP:
方式 1 , 如图 1所示， 在 DSP工程 11源文件中添加测试代码， 先将待测 数据与运行条件写入 DSP, 然后在相应的测试点将运算结果和仿真结果进行 比对判断是否正确。 这种方法的缺点很明显， 对 DSP工程源代码进行改动容 易引入新的错误， 并且不同的测试数据和测试条件都需要重新更改 DSP工程 的代码， 效率低下。  Mode 1, as shown in Figure 1, add test code to the DSP project 11 source file, first write the data to be tested and the operating conditions to the DSP, and then compare the operation result with the simulation result at the corresponding test point to determine whether it is correct. . The shortcomings of this method are obvious. It is easy to introduce new errors in the modification of the DSP engineering source code, and different test data and test conditions need to change the code of the DSP project, which is inefficient.
方式 2 , 如图 2所示， 对于某些系列的 DSP芯片， 可以使用相关的算法 模拟软件开发编程接口 21使算法模拟软件可以直接和 DSP开发工具通信， 可以无需对 DSP源程序编写测试代码便可以对 DSP工程进行测试。这种方法 的缺点是， 只有固定厂商的固定芯片可以适配此编程接口， 大多数其它厂家 的 DSP芯片不支持此编程接口， 兼容性能差。 Mode 2, as shown in Figure 2, for some series of DSP chips, the relevant algorithm simulation software development programming interface 21 can be used to enable the algorithm simulation software to directly communicate with the DSP development tool, without writing test code to the DSP source program. The DSP project can be tested. This method The disadvantage is that only the fixed chip of the fixed manufacturer can adapt to this programming interface. Most other manufacturers' DSP chips do not support this programming interface, and the compatibility is poor.
方式 3 , 如图 3所示， 在现有的 DSP开发软件 31中集成脚本运行环境， 例如在现有的 DSP开发环境 Code Warrior中嵌入脚本运行环境。 可以在脚本 环境中运行仿真脚本， 实现一定的自动化， 并且无需改动 DSP工程代码。 此 方法的不足是仿真环境封闭于 DSP开发工具中， 对于不同测试用例需要编写 相应的测试脚本， 同时也需要开发人员熟悉脚本编程。  Mode 3, as shown in FIG. 3, integrates a script running environment in the existing DSP development software 31, for example, embedding a script running environment in an existing DSP development environment Code Warrior. Simulation scripts can be run in a scripting environment for some automation and without the need to change DSP engineering code. The shortcoming of this method is that the simulation environment is enclosed in the DSP development tool. It is necessary to write the corresponding test script for different test cases, and also requires the developer to be familiar with script programming.
