Abstract

Abstract: Engineering and Scientific Computation Accelerator (ESCA) is a heterogeneous multi-core architecture to accelerate computation-intensive parallel computing in scientific and engineering applications. This paper described an implementation of Laplace transform on the hybrid system based on ESCA coprocessor, and the performance of Laplace transform on the quad-core prototype ESCA was exploited. The experimental results show that the ESCA can accelerate program of compute-intensive applications fairly well.

Key words: heterogeneous multicore, coprocessor, compute-intensive, Laplace transform, parallel computing

摘要： 基于自主研发的新颖异构多核工程科学计算加速协处理器（ESCA）体系结构，实现了图像Laplace变换算法。针对ESCA架构特点，采用子字并行计算和访存延迟隐藏等机制，进行了一系列并行算法优化，并在四核ESCA处理器原型上对图像Laplace变换算法的进行了性能评测。实验结果表明，对于计算密集型计算任务，ESCA处理器具有良好的计算加速效果。
