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.

集成硬件垃圾收集器（IHGC）是一个实验性的体系结构，它为嵌入式系统中的自动内存管理引入了硬件支持。IHGC采用了一种新的内存模型，并实现了一种用于分配内存的创新技术。早期的可行性研究发现，IHGC提供了许多优于传统软件垃圾收集的优点，同时只需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关键系统（MCS）中具有吸引力。该项目的目的是表明IHGC可以用于混合关键性与实时要求。此外，IHGC的扩展将被提出，以保证进程内存隔离，而不依赖于传统的内存保护单元（MPU）在现代嵌入式系统中使用。该项目的结果将显示混合关键嵌入式系统的IHGC的可行性。
