The embedded processor of the future will have multiple heterogeneous processors on a single chip integrated with a large shared memory. Many of the applications for this processor will have strict real-time requirements. This project investigates novel architectural and system software features that can allow such a processor to support complex real-time applications. Architectural features that limit shared memory contention and reduce synchronization overhead will be studied in order to reduce latencies and make thread execution times more predictable. The project will also explore the use of specialized I/O processors having direct and equal access to shared memory in order to minimize interference of I/O operations on real-time thread execution. Novel techniques for scheduling real-time threads on a heterogeneous multiprocessor-on-a-chip will also be studied.

未来的嵌入式处理器将在单个芯片上集成多个异构处理器，并集成大容量共享内存。该处理器的许多应用程序都有严格的实时要求。 该项目研究新颖的架构和系统软件功能，使此类处理器能够支持复杂的实时应用程序。 将研究限制共享内存争用和减少同步开销的架构功能，以减少延迟并使线程执行时间更可预测。 该项目还将探索使用能够直接且平等地访问共享内存的专用 I/O 处理器，以最大程度地减少 I/O 操作对实时线程执行的干扰。 还将研究在异构片上多处理器上调度实时线程的新技术。
