介绍了vhdl设计fpga时仿真和综合的过程，包括软件的应用和一些注意事项，相信会对大家有所帮助-introduced a VHDL design and simulation when they simply integrated process, including software applications and some attention to matters, we believe it will help

心率指心脏每分钟搏动的次数, 它能够反映心脏的工作状态。正常心率决定于窦房结的节律性, 成人静息时约60～100 次/ min , 平均约75次/ min。心率可因年龄、性别及其他因素而变化。初生儿心率约130 次/ min , 随年龄增长而逐渐减慢, 至青春期乃接近成人的心率。女性心率比男性稍快 运动员心率较慢。成人安静心率超过120 次/ min 者, 为心动过速 低于40 次/ min 者为心动过缓。心率受植物性神经和体液因素调节。-Heart rate means the number of pulse per minute, it can reflect the work of the state of the heart. Normal heart rate determined by the rhythm of the sinoatrial node, resting adult is about 60 ~ 100 times/min, an average of about 75 times/min. Heart rate may be due to age, gender and other factors change. Heart rate of newborn infants of about 130/min, growth has gradually slowed down with age, to adolescence adult heart rate is near. Women slightly faster rate than men athletes slow heart rate. Quiet adult heart rate over 120 times/min, and for the tachycardia less than 40 times/min for bradycardia. Heart rate by the plant regulate neural and humoral factors.

介绍了一种基于ARM9和Linux操作系统的心电记录仪。该记录仪以32位低功耗ARM9微处理器S3C2410X为核心,在其上移植了Linux操作系统,利用轻量级的图形用户界面支持系统MiniGUI进行软件界面开发-Introduce an approach based on ARM9 and Linux operating systems ECG recorder. The logger to 32 low-power ARM9 microprocessor S3C2410X for the core of the transplant in its Linux operating system, the use of lightweight graphical user interface support system for software interface development MiniGUI

LCD Driver datasheet The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of SPFD54126A adopts OP-AMP structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power consumption.

射频识别芯片在汽车智能防盗报警装置中的应用,较之普通的磁卡和ＩＣ 卡，ＲＦＩＤ技术具有使用方便、数据交换速度快、便于维护和使用寿命长等优点。特别是它解决了无源（卡中无电源）和免接触这两大难题。-Radio frequency identification chip in the smart car anti-theft alarm device, compared with ordinary magnetic cards and IC cards, RFID technology has the ease of use, data exchange speed, ease of maintenance and long life etc.. In particular, it has resolved a passive (no power supply card) and free access to these two problems.

2005年电赛：简易逻辑分析仪 ，本人试验的，可惜知识培训-the year of 2005

主要给出msp430的程序代码，当然这只是嘴基本点程序集，具体程序代码还需要进一步涉及〉-MSP430 main program code is given, of course, this is only the basic point of the mouth assembly, the specific program code also needs to be further involved in
