摘要

描述了在GRAPE-II(图形快速原型环境)中支持的两个新特性:几何并行性和循环静态数据流。GRAPE-II旨在作为多处理器上数字信号处理(DSP)应用快速原型的系统级工具。GRAPE-II完全支持异构目标多处理器上的多速率和异步DSP应用程序的代码生成。本文详细介绍的第一个特性是几何并行，它允许程序员有效地指定数据并行操作，即多个相同的函数对不同的数据集进行操作。第二个特性是循环静态数据流，它允许指定循环更改的数据依赖项，同时仍然导致静态调度

Geometric parallelism and cyclo-static data flow in GRAPE-II

Describes two novel features that are supported in GRAPE-II (Graphical RApid Prototyping Environment): geometric parallelism and cyclo-static data flow. GRAPE-II is intended as a system level tool for the rapid prototyping of digital signal processing (DSP) applications on multiprocessors. GRAPE-II fully supports code generation for multi-rate and asynchronous DSP applications on heterogeneous target multiprocessors. The first feature detailed in the paper, geometric parallelism, allows the programmer to efficiently specify data parallel operations, where multiple identical functions operate on different data sets. The second feature, cyclo-static data flow, enables the specification of cyclicly changing data dependencies, while still leading to static schedules.<>
