摘　　要：介绍了采用SOPC技术来设计一个共享资源的可穿戴计算机三处理器系统,主处理器主要负责操作系统和应用软件的运行,网络处理器主要负责进行报文处理,DSP处理器主要负责对视频图像数据进行处理.阐述了基于Nios Ⅱ和FPGA的多处理器系统的实现机制,讨论利用硬件互斥核实现多处理器资源共享的方法,并给出硬件设计的具体步骤以及软件设计、调试方法和关键技术.介绍了网络处理器Nios Ⅱ的结构特点和自定义指令以及基于Nios Ⅱ软核处理器的网络处理器转发软件的设计方法和基于视频图像处理的DSP处理器的设计方法.经验证,采用此技术设计的三处理器系统很好地适应了可穿戴计算机微小型化和低功耗的设计要求.This paper describes the use of SOPC technology to design a wearable computer system with three processors sharing resources, the main processor is mainly responsible for the running of the operating system and application software , the network processor is mainly responsible for handling messages, the DSP processor is mainly responsible for the processing of the video and image data. This paper describes in detail the implementation mechanism of the muhiprocessor system based on Nios Ⅱ and FPGA, discusses the use of hardware mutex to realize multi-processor resource sharing and gives the specific steps for the design of the hardware, the design of the software, testing methods and key technology. Introduces the structural features of the network processor Nios Ⅱ and customized instructions and design methods for forwarding software of the network processor based on the Nios Ⅱ soft-core processor and design methods for the DSP processor used for the processing of the video and image data. After verification, the three-processor system very well adapted to the wearable computer＇s micro and small and low-power design requirements.
