【摘要】：针对嵌入式系统硬件平台采用纯软件仿真并对嵌入式软件进行功能级测试的相关研究存在较多不足,缺乏整体、统一、灵活、标准的仿真部件间接口,致使不同体系、类型的处理器仿真核与各类外设间较难进行快速、直接的整合与交互、导致缺乏系统级可配置能力、各类仿真核与调试器(GDB)间不能进行直接、有效地互联和交互,从而无法达到可定制、组件化的系统级仿真及虚拟测试环境快速搭建目标.基于组件化思想,提出一套处理器仿真、外设仿真和调试器(GDB)三者间可进行直接、快速交互的标准结构、标准接口和基本处理逻辑,优化和删减了GDB层次,扩充了新功能,使之在运行时可动态加载、支持多种仿真处理器体系.研发了虚拟测试系统,验证了所提方法、结构、接口的有效性和正确性,与其他同类技术、项目进行了综合能力比较.结果表明本文所提方法、技术具有较多优势.
[Abstract]:In view of the embedded system hardware platform using pure software simulation and the embedded software to carry on the function level test related research has many shortcomings, lacks the whole, the unification, the flexibility, the standard simulation component interface, causes the different system, It is difficult to integrate and interact quickly and directly between the emulation core of the processor and all kinds of peripheral devices, which leads to the lack of system level configurable ability, and the direct and effective interconnection and interaction between all kinds of emulation cores and the debugger GDBs. Therefore, the system level simulation and virtual test environment can not be customized. Based on the idea of componentization, a set of processor simulation, peripheral simulation and debugger GDB can be directly implemented. The fast interactive standard structure, standard interface and basic processing logic, optimize and delete the GDB hierarchy, expand the new function, make it load dynamically at run time, support various simulation processor systems. The validity and correctness of the proposed method, structure and interface are verified and compared with other similar technologies and projects. The results show that the proposed method and technology have many advantages.
