【摘要】 可重用设计方法源于SoC(System on a Chip片上系统)的设计人员对大规模复杂芯片设计方法的总结和归纳,即使用以前设计完成且已经过验证的知识产权核(IP核)构建系统芯片的设计方法,是一种有效的设计方法与先进的设计理念。近年来,随着可编程器件技术的进步,可编程逻辑阵列FPGA逻辑容量不断提高而价格在不断的降低,在FPGA上实现SoC即SOPC技术已成为了一种发展趋势。SOPC( System on a Programmable Chip)是一种灵活、高效的SoC解决方案。首先它是片上系统(SoC),由单个芯片完成整个系统的主要逻辑功能;其次它是可编程系统,具有灵活的设计方式,可裁减,可扩充,可升级,并具有软硬件体系可编程的功能。本文将可重用设计方法与SOPC技术相结合,将传统的停留在板级设计层面的嵌入式系统硬件设计提升到基于可编程逻辑芯片上的系统级设计,在单片FPGA上使用IP复用技术集成了NIOS II软核处理器、图像采集与处理IP核、用户输入输出人机接口、通讯模块接口等,实现了嵌入式掌纹识别系统。另外,通过对升级与更改FPGA硬件逻辑以及系统软件,可使系统平台支持二维条码扫描、RFID卡读写,门禁控制等功能,实现了软硬件体系的可重构与平台的可重用。

【Abstract】 The electronics industry has entered the era of multimillion-gate chips, now SoC designers use reuse methodology, which is based on reusing and design of intellectual property (IP) to increase efficiency of complex IC design.With the development of technology of programable logic device, a single chip FPGA is available to contain several millions transistors so implement SoC(System on Chip) on FPGA which is called SOPC (System on Programable Chip) becomes a industry trend. SOPC is a flexible and efficient SoC solution. Firstly it is a SoC, a single chip contain the main system functions. Secondly, SOPC is a programmable system which has the characteristics such as low cost, high performance, flexibility in designing, configurable function modules, soft/hardware reconfigurable and so on.Use the revolutionary SOPC technology and guided by Reuse Methodology and combine soft/hard-ware coordination designing idea, this thesis attempts to changes the focus of system design from the board-level to the chip-level. This thesis successfully integrated NIOSII CPU, image capture and process IP core, user interface module and communication interface to a single FPGA chip and realize a palm print recognition embedded system platform. Through update FPGA logic and system software, this platform can support two-dimension code, RFID card and Security control functions, which prove the advantages of SoPC technology -- soft/hardware reconfigurable and platform reuse-able.
