Diagnostics for real time distributed multi-core architecture in avionics

嵌入式计算机系统是市场上出现的许多高科技设备背后的智能，从飞机到火车、汽车、手机和家用电器。在许多应用中，嵌入式计算机系统起着至关重要的作用，需要不断地高速、实时地分析大量的参数。在这种情况下，嵌入式多核处理器被越来越多地使用，因为有多个处理器可以并行工作，以实时处理所有信息。在航空航天行业尤其如此，飞机上集成的传感器数量很快就会从几十个增加到数百个。这不仅可用于监测飞机速度，还可用于监测机翼上一百个点的升力，例如用于检测结冰问题。在这些嵌入式多核系统及其模拟器上运行的实时多线程程序的设计非常复杂，需要更好的调试和性能分析工具。在该项目中，将把目前非常高效的低开销、低干扰跟踪算法扩展到实时嵌入式多核系统和仿真器中，并开发新的专用性能分析和调试模块。因此，有了这些新的软件开发工具，加拿大航空航天和嵌入式计算机系统行业将能够更有效地设计新的复杂实时多核系统，避免延误，并以更快的速度和更少的缺陷将产品推向市场。

Embedded computer systems are the intelligence behind many of the high technology devices appearing on the market, from planes to trains, cars, mobile phones and house appliances. In many applications, the embedded computer system has a critical role and needs to constantly analyze at high speed and in real time a large number of parameters. In such cases, embedded multi-core processors are increasingly used, since several processors are available to work in parallel to process in real time all the information. This is especially true in the aerospace industry where the number of sensors integrated in planes will soon go from a few tens to several hundreds. This is useful to monitor not only the plane speed but also the lift at a hundred points on the wings, for example to detect icing problems. The design of real-time multi-threaded programs to run on these embedded multi-core systems and their simulators is exceedingly complex and requires better debugging and performance analysis tools. In this project, recent extremely efficient algorithms for low overhead, low disturbance tracing will be extended to real-time embedded multi-core systems and simulators, and new special purpose performance analysis and debugging modules will be developed. As a result, with these new software development tools, the Canadian aerospace and embedded computer systems industry will be able to tackle the challenge of designing the new sophisticated real-time multi-core systems much more efficiently, avoiding delays and bringing products to market faster and with fewer defects.
