The past decade has seen an explosion of machine learning research and appli- cations; especially, deep learning methods have enabled key advances in many applicationdomains,suchas computervision,speechprocessing,andgameplaying. However, the performance of many machine learning methods is very sensitive to a plethora of design decisions, which constitutes a considerable barrier for new users. This is particularly true in the booming field of deep learning, where human engineers need to select the right neural architectures, training procedures, regularization methods, and hyperparameters of all of these components in order to make their networks do what they are supposed to do with sufficient performance. This process has to be repeated for every application. Even experts are often left with tedious episodes of trial and error until they identify a good set of choices for a particular dataset.

The PW2606B is a front-end over voltage and over current protection device. It achieves wide inputvoltage range from 2.5VDC to 40VDC. The over voltage threshold can be programmed externally orset to internal default setting. The low resistance of integrated power path nFET switch ensures betterperformance for battery charging system applications. It can deliver up to 1A current to satisfy thebattery supply system. It integrates the over-temperature protection shutdown and Auto-recoverycircuit with hysteresis to protect against over current events

The PW2228A is a high efficiency single inductor Buck-Boost converter which can supply theload current up to 1.5A. It provides Auto-transition between Buck and Boost Mode. The PW2228Aoperates at 2.4MHz switching frequency in CCM. DC/DC converter operates at Pulse-Skipping Modeat light load. The output voltage is programmable using an external resistor divider, or is fixed to3.3V internally. The load is disconnected from the VIN during shutdown.The PW2228A is available in TDFN3X3-10 package.

首先下载软件，解压软件，安装在程序中找到SEGGER,选里面的J-FLASH，进入界面，刚开始的那个界面可以忽略，不用建project也可以；单击菜单栏的“Options---Project settings”打开设置，进行jlink配置;正在General选项，选择“USB”，一般都是默认配置，确认一下即可;然后在CPU选项，选择芯片型号，先选择“Device”才能选择芯片型号，芯片型号，要根据你使用的芯片进行选择;在Target interface选项 里面选择SWD模式;首先Target里面选“Connection”连接目标芯片，然后 Target--Auto进行程序烧写;首先Target里面选择“Connection”连接目标芯片，然后 Target--Auto进行程序烧写.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.

第一章引言目前基于单片微机的语音系统的应用越来越广泛，如电脑语音钟、语音型数字万用表、手机话费查询系统、排队机、监控系统语音报警以及公共汽车报站器等等。本文作者用Flash单片机ANT89C51和录放时间达90%的数码语音芯片ISD2590设计了一套智能语音录放系统，实现了谱音的分段录取、组合回放，整段录取.循环播放，通过软件修改可以实现很多场合的应用。第二章ISD2590语音芯片本系统采用关国ISD公司的ISD2590芯片，ISD2500系列具有抗断电、音质好，使用方便等优点。它的最大特点在于片内E2PROM容量为480K（1400系列为128K），所以录放时间长；有10个地址输入端（1400系列仅为8个），寻址能力可达1024位；最多能分600段；设有OVF（溢出）端，便于多个器件级联。2.1内部框图图2-1为ISD2590芯片的内部结构框图。录音时，语音信号从MIC，MICREF（17，18）引聊输入，经过一个前置放大器放大，该放大器的增益由AGC（Auto Gain Control，19）引脚所接的器件的伯控制。经放大的信号从ANAOUT脚输出，经过阻容注被后ANAIN进入芯片内部。然后经过放大和滤波后存入EEPROM阵列中，放音时，在正确的时序控制的前提下，声音信号将从EEPROM中经滤波放大后从SP+，SP一中输出。
