Derivation and timing analysis of concurrent real-time software

并发实时软件的推导与时序分析。安全关键计算机系统通常由并发实时软件控制。这种系统的保证需要严格的方法来推导软件和验证其逻辑和时序的正确性。这个项目将直接解决这个问题，通过一个新的范例，实时编程，是基于一个机器独立的并发实时编程语言，明确表示程序内的时间期限。这允许将开发过程划分为独立于机器的阶段和依赖于机器的阶段，独立于机器的阶段导出满足高级规范的程序，依赖于机器的阶段检查生成的机器代码中的时间期限是否得到保证。

Derivation and timing analysis of concurrent real-time software. Safety-critical computer systems are commonly controlled by concurrent real-time software. Assurance of such systems requires rigorous methods for deriving the software and verifying its logical and timing correctness. This project will directly address this problem via a new paradigm for real-time programming that is based on a machine-independent concurrent real-time programming language, that explicitly represents timing deadlines within programs. This allows a partitioning of the development process into a machine-independent phase that derives a program to meet a high-level specification, and a machine-dependent phase that checks that the timing deadlines within the generated machine code are guaranteed to be met.
