An embedded multicore platform exploration in video application utilizing FPGA

摘要

Multi-processor is not a new technology, but with the development of modern silicon technology1, it is possible to integrate multiple cores in a single chip package, which is called multicore processor. Whether in the desktop personal machine, or embedded applications, multicore processor has been a general trend, due to the requirement of high performance and design problems in single-core processor. Surrounded multi-screen provides a better sense of reality, which is widely used in the surveillance, military, exhibitions, and so on. With the advantages in parallel processing, multicore technology- has an important practical significance and a broad prospect in these applications. In this paper, an exploration on multicore architecture is mainly focused on, from the perspectives of processing elements, memory hierarchy, and on-chip interconnection. A basic platform for multi-screen display is implemented on the Xilinx field programmable gate array (FPGA), and it illustrates that there is a 3.6 times higher performance than the corresponding single-core design, which provides a helpful guidance and revelation to further researches.
