data are often used interchangeably, they are actually very different. Data is a set of unrelated information, and as such is of no use until it is properly evaluated. Upon evaluation, once there is some significant relation between data, and they show some relevance, then they are converted into information. Now this same data can be used for different purposes. Thus, till the data convey some information, t

Biokey200/URU4000B指纹仪驱动与SDK 升级到4000B注意事项 原使用Biokey SDK的客户，需要升级SDK开发包并安装4000B的驱动。 注意：安装4000B驱动前需卸载4000的驱动。 其步骤如下： 1、备份注册表：在开始菜单中的‘运行’中运行‘Regedit’，打开注册表，然后选中注册表中的 [HKEY_LOCAL_MACHINE\SOFTWARE\DigitalPersona]项，单击菜单上的注册表－>导出注册表文件，将该项导出到文件中。 2、卸载4000的驱动程序（Biokey200/URU4000驱动）。 卸载步骤如下： 1）运行控制面板中的“添加/删除'程序”，卸载指纹采集设备的驱动程序; 2）在开始菜单中的‘运行’中运行‘Regedit’，查看 HKEY_LOCAL_MACHINE\Software\DigitalPersona键值，如果有则删除； 3）查看系统安装目录下system32 目录（win98为windows\system）下的DP*.dll ，如果有则全部删除； 4）察看Program files\zksoftware\biokey200目录，如果有则整个删除。 3、重新启动计算机，安装4000B驱动程序, 4、将Biokey SDK升级,用新的Biokey.ocx替换旧的控件，一般情况下，VB程序可以直接使用，Delphi程序则需要重新编译。 5、用4000B的驱动，必须使用新的控件，目前只完成了1：N的控件升级，1：1的控件，暂时使用原来3.5版本的控件。 6、测试原来登记的指纹模板，看是否能正常比对，如果不能，双击原来备份的注册表文件，添加到注册表中，就可以了。 原来使用U.R.U SDK的客户，需要更新驱动程序，同时由于U.R.U的模板有一些变化，所以需要一些改动，我们提供一份升级须知，请查看ReleaseNotes.txt.升级过程前三个步骤同上，只是需要注意，卸载的时候，查看Program files\DigitalPersona目录，如果有则整个删除。

The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit digital audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio™ suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3204’s digital audio processing core. TAS3204 processing capability includes speaker equalization and crossover, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms. The TAS3204 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations. Four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs ensure that high quality audio is maintained through the whole signal chain as well as increasing robustness against noise sources such as TDMA interference. The TAS3204 is composed of eight functional blocks: Clocking System Digital Audio Interface Analog Audio Interface Power supply Clocks, digital PLL I2C control interface 8051 MCUcontroller Audio DSP – digital audio processing 特性 Digital Audio Processor Fully Programmable With the Graphical, Drag-and-Drop PurePath Studio™ Software Development Environment 135-MHz Operation 48-Bit Data Path With 76-Bit Accumulator Hardware Single-Cycle Multiplier (28 × 48)
