Design and Evaluation of Asymmetric and Symmetric 32-core Architectures on FPGA

Abstract

Due to the advances in semiconductor technologies, recent FPGA devices are able to implement a number of CPU cores to realize high-performance embedded systems. This paper presents a case study on design, implementation and evaluation of manycore architectures on an FPGA. Two types of 32-core architectures with different topologies, i.e., asymmetric and symmetric architectures, are designed and implemented on an FPGA, together with an OpenCL-based software framework. The performance of the two architectures is evaluated based on actual measurement using various application programs.
