【摘要】：随着近些年信息技术的飞速发展，如今的嵌入式系统已经成为诸多行业研究和应用的热点。因为flash具有非易失性、读取速度快和功耗低等特点被广泛的应用于嵌入式系统，但芯片测试存在周期长，成本高等问题。本文结合0.13μm嵌入式闪存存储器和90nm闪存存储器的研发项目，提出了一种基于单片机AT89C51SND1的可实现MP3播放的flash测试的设计方法，以AT89C51SND1为核心，设计外围电路，完成原理图设计、PCB板设计并装配成实验开发板，并利用c语言调整编译器KeilC和ISP在线调试软件FLIP，将嵌入式技术融入单片机系统开发和应用，调试实现具有多媒体播放功能并测试flash功能和性能。在与老师同学合作设计、制造、调试开发板的过程中，学习实践软、硬件的设计思想、开发的流程、相关软件的使用、解决问题的能力，合作完成了开发板的设计和制版工作，，并完成部分flash功能和性能的测试。
[Abstract]:With the rapid development of information technology in recent years, embedded system has become a hot research and application in many industries. Because flash has the characteristics of non-volatile, fast reading speed and low power consumption, it has been widely used in embedded systems. However, the chip test has the problems of long period and high cost. Combined with the R & D project of 0.13 渭 m embedded flash memory and 90nm flash memory, this paper presents a design method of flash test for MP3 playback based on MCU AT89C51SND1. The peripheral circuit is designed with AT89C51SND1 as the core. The schematic design is completed and the PCB board is designed and assembled into an experimental development board. The compiler KeilC and ISP on-line debugging software FLIPA are adjusted by c language. The embedded technology is integrated into the development and application of single-chip microcomputer system. Debug implementation has multimedia play function and test flash function and performance. In the process of designing, manufacturing and debugging the development board with teachers and classmates, learn to practice the design ideas of software and hardware, the process of development, the use of related software, and the ability to solve problems. Cooperation completed the development board design and plate making, and some of the flash function and performance testing.
