基于UOS系统下威焱831的PCIE-DMA设计

Design of PCIE-DMA for Weiyan 831 based on UOS system

阐述一种国产化WY-831处理器和FPGA芯片异构通信方案的设计,此方案有效解决国产操作系统的异构计算场景下,国产处理器与FPGA进行高速通信和数据交互问题。探讨硬件框架设计和内核驱动软件设计,对方案进行测试验证,针对不同的数据量进行吞吐量测试。

This paper describes the design of a heterogeneous communication scheme between a home-made WY-831 processor and FPGA chips.This scheme effectively solves the high-speed communication and data interaction problems between a home-made processor and FPGA in the Heterogeneous computing scenario of a home-made operating system.It explores hardware framework design and kernel driver software design,tests and verifies the solution,and conducts throughput testing for different data volumes.
