| 摘 要： | 提出一种适用于图形和图像处理的高效并行阵列机结构。该结构的处理单元有单指令多数据(SIMD)和多指令多数据(MIMD)两种运行模式,兼有异步执行机制、硬件的多线程管理器和高效通信机制。这些机制使得此种阵列机能够实现效率很高的线程级并行运算、数据级并行运算和操作级并行运算。尤其值得指出的是,此种阵列机的流处理性能可以达到或接近专用集成电路的性能。该结构还能有效实现静态与动态数据流计算。

| Abstract: | A novel "thin-core" array architecture for graphics and image processing is proposed in this paper.A processing element(PE) in this machine is able to execute in both SIMD and MIMD modes.The PE has mechanisms for asynchronous inter-thread communication and efficient execution.A PE also contains a hardware thread manager to realize one-step context switching.This architecture is highly efficient in realizing thread-parallel computation,data-parallel computation and operation parallel computation.In particular,the performance of this architecture is comparable with ASIC when used for stream processing.This architecture is capable of implementing high-performance,classical static and dynamic dataflow computation. |
