Abstract

Virtual Platforms (VPs) are advantageous to develop and debug complex software for multi- and many-processor systems-on-chip (MPSoCs). VPs provide unrivalled controllability and visibility of the target, which can be exploited to examine bugs that cannot be reproduced easily in real hardware. However, VPs as used for debugging provide only traditional interfaces, such as step-based debuggers and traces, that do little to help with the enormous complexity of MPSoCs and their parallel software. Finding a bug is still largely left to the developer's experience and intuition, using manual means rather than automated solutions. To bridge this gap, this paper presents a novel VP debug visualization and control framework for concurrent software that allows examining and steering the target by means of an abstract representation of its inter-task interactions. Our framework reduces the effort required to understand complex concurrency patterns and helps to expose bugs.

基于确定性事件控制的虚拟平台MPSoC软件调试

虚拟平台在多处理器和多处理器片上系统(mpsoc)中具有开发和调试复杂软件的优势。副总裁提供了无与伦比的可控性和目标的可见性，这可以用来检查在真实硬件中不容易复制的错误。然而，用于调试的vp只提供传统的接口，例如基于步骤的调试器和跟踪，这些接口对mpsoc及其并行软件的巨大复杂性几乎没有帮助。寻找漏洞仍然很大程度上取决于开发人员的经验和直觉，使用手动方法而不是自动解决方案。为了弥补这一差距，本文提出了一种新的并行软件的VP调试可视化和控制框架，该框架允许通过任务间交互的抽象表示来检查和指导目标。我们的框架减少了理解复杂并发模式所需的工作量，并有助于暴露bug。
