文档介绍：数字存储示波器的设计
摘要
便携式数字存储示波器是现代示波器发展的方向之一,但由于其技术含量及高,尚无本国产品上市,属于测试仪表方面众目交注的领域。ARM是32位的RISC处理器,高性能、低功耗是其显著特点,已被广泛应用与各种潜入式领域。在便携式电子产品的设计中,采用FPGA器件可以将原来的电路板级产品集成为芯片级产品,做到功耗低、可靠性高。
本文提出了一种基于ARM+FPGA结构的便携式数字存储示波器硬件平台设计方案,FPGA主要用于大量的数据存储,ARM则负责数据的进一步处理和控制波形的重建、显示和数据永久存储。系统的前端芯片选用Altera公司最新一代的MAX Ⅱ系列高性能、低功耗FPGA芯片,系统后端ARM处理器则选用三星公司基于ARM7TDMI-S内核的多功能、低功耗ARM单片机——LPC2210,系统利用彩色LCD作为终端显示设设备,利用其基于自带的存储器存储永久波形数据,且自带有JTAG调试接口,便于设计。

ABSTRACT
It is one of the directions of modern oscilloscope development that the portable digital storage oscilloscope, because its technological content is extremely high, there are no national products to go on the market, It is a field concerned by a lot of eyes in testing the instrument. ARM is 32 bits RISC processor, high performance, low consumption are its remarkable characteristic, have already widely used in various kinds of embedded fields. In portable electronic product design, using FPGA may upgrade printed circuit product to integration circuit, depress power consumption and enhance reliability.
The paper has proposed a kind of hardware platform design plan of the portable digital storage oscilloscope based on ARM+FPGA structure. FPGA is used as data memory, ARM is responsible for the back end waveform rebuilding, displaying and the data storing for ever. The chip of the systematic front, we select pany’s MAX Ⅱseries for use that is the most new generation high performance, low consumption FPGA chip, the ARM processor of the systematic back end, we select pany’s the multi-functional、low consumption ARM chip based on ARM7TDMI-S kernel ——lpc2210, the system utilizes multicolor LCD as the terminal display device, to utilize the memory of lpc2210 to store the waveform data for ever, the JTAG debugging interface of lpc2210 make it convenient for design.
