The IHGC architecture for Mixed Criticality Embedded Systems

集成硬件垃圾收集器（IHGC）是一种实验性架构，它为嵌入式系统中的自动内存管理引入了硬件支持。IHGC提出了一种新的内存模型，并实现了一种创新的内存分配技术。早期的可行性研究发现，IHGC比传统的软件垃圾收集提供了许多好处，同时只需要对现有应用程序进行最小的代码更改。特别是，IHGC执行自动边界检查并防止内存泄漏，使其在安全性，可靠性和可预测性至关重要的混合临界系统（MCS）中具有吸引力。该项目的目的是证明IHGC可以用于具有实时需求的混合临界。此外，将提出对IHGC的扩展，以保证进程内存隔离，而不依赖于现代嵌入式系统中使用的传统内存保护单元（MPU）。该项目的结果将显示IHGC用于混合临界嵌入式系统的可行性。

The Integrated Hardware Garbage Collector (IHGC) is an experimental architecture that introduces hardware support for automatic memory management in embedded systems. IHGC imposes a novel memory model and implements an innovative technique for allocating memory. An early feasibility study found that IHGC offers many benefits over traditional software garbage collection while requiring minimal code changes to existing applications. In particular, IHGC performs automatic bounds checking and prevents memory leakage making it attractive for use in Mixed Criticality Systems (MCS) where safety, reliability and predictability are paramount. The aim of this project is to show that IHGC can be used in Mixed Criticality with real-time requirements. Furthermore, an extension to IHGC will be proposed to guarantee process memory isolation without relying on the traditional Memory Protection Unit (MPU) used in modern embedded systems. The outcome of this project will show the feasibility of IHGC for Mixed Criticality Embedded Systems.
