摘　　要：针对目前流量计算机存在成本过高、计算速度较慢等问题,研制了基于内含矢量浮点单元VFP的S3C6410嵌入式微处理器、Linux操作系统和通过内部串行总线联接多达12个流量采样输入通道的气体流量计算机。主要阐述了该流量计算机的硬件和软件的设计。测试结果表明所设计的气体流量计算机能满足计量精度和实时性的要求。Due to the high price and low computing speed of current flow computers, a new kind of multifunctional gas flow computer based on S3C6410 CPU with Vector Floating Point （VFP） unit, Linux operating system, supporting up to 12 flow sampling channel and inner bus network was proposed. This paper gave a description of both hardware and software desi^n of the gas flow computer. The results of the experiments show that this proposed flow computer meets the measuring requirements of both accuracy and real-time.
