This paper presents an OpenCL-based software framework which we have developed for a heterogeneous multicore architecture on Zynq-7000 SoC. In this work, the heterogeneous architecture is designed with two hardmacro Cortex-A9 cores and two soft-macro MicroBlaze cores. A major advantage of our OpenCL framework is that it can execute OpenCL kernel programs in three ways. Experiments show the usefulness of the OpenCL framework.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
