This research focuses on the compiler and architectural issues of concurrent multithreaded architectures. These architectures allow multiple threads to be active simultaneously to achieve multiple instruction issue in a single machine cycle. The architectural research focuses on the design of thread execution units that include support for communication between threads, for speculative thread execution, and for thread pipelining. Simulation at the functional and register-transfer levels will be the primary tool for this research. The compiler research focuses on integrating optimization for thread and instruction level parallelism. This research will take place in the context of modifications to the gcc compiler. While threads can be used to allow multiple independent programs to execute concurrently, the primary focus of this project is speeding up the execution of a single program.

本研究重点关注并发多线程架构的编译器和架构问题。 这些架构允许多个线程同时活动，以实现在单个机器周期内发出多个指令。 架构研究的重点是线程执行单元的设计，包括对线程之间通信、推测线程执行和线程流水线的支持。 功能和寄存器传输级别的仿真将是这项研究的主要工具。 编译器研究的重点是线程和指令级并行性的集成优化。 这项研究将在 gcc 编译器修改的背景下进行。 虽然线程可用于允许多个独立程序同时执行，但该项目的主要焦点是加速单个程序的执行。
