博创科技 UP-Star2410 开发板 硬件说明书

博创科技 UP-Star2410 开发板 硬件说明书

UP-Star2410开发板硬件说明书一、UP-Star2410硬件资源1.核心资源S3C2410 ARM CPU、32M SDRAM、64M NAND FLASH。

2. 100M网卡,DM9000AE。

3.一个USB主口,一个USB从口。

4.一个RS232串口DB9接口。

另有一路RS232串口和TTL串口从扩展插座上引出。

5.扩展插座,引出所有总线信号(经过驱动芯片)和未占用资源。

6. LCD和触摸屏接口,外接专配液晶屏/触摸屏板。

7.电源、复位、JTAG、RTC等基本资源和接口,支持博创UP-LINK和J-LINK仿真器。

8.设置了IO控制的LED和可产生硬中断的5位导航按键等简单调试资源。

二、电路原理说明1.S3C2410的OM0和OM1两个引脚用来配置启动方式和Bank0的总线宽度。

当OM[1:0]=00时从NandFlash启动,此时Bank0不能使用;当OM[1:0]=01时从Bank0启动,并配置为16Bit宽度,也就是从NorFlash启动。

UP-Star2410上固定设置为从NandFlash启动。

2.S3C2410从NandFlash引导时,通过NCON脚的电平来配置NandFlash控制器的寻址字节数。

从这点上看,无法从128M及以上容量的大块NandFlash引导,因为128M Flash的寻址方式和块页组织都有所变化。

UP-Star2410上将NCON接高电平,支持64M NandFlash引导。

3.K9F1208是三星公司的NandFlash芯片,而S3C2410内部具有Nand 控制器,所以K9F1208直接和S3C2410连接,并可以从NandFlash引导。

NandFlash的原理图如下所示:4.核心板的SDRAM采用两片HY57V561620,每片32M字节,总的SDRAM为32MB。

HY57V561620数据宽度16Bit,内部分为4个Bank,每Bank为4M字节。

AbstractShared pixel technology is most common in recent small pixel CMOS image sensors. In the case of vertically shared pixels, it has been observed horizontal line FPN with the period of shared pixels when highlight scene is imaged and integration period is reduced to very short time by electronic shuttering. We present here the reason of the phenomena and the technique for reducing it. As the results, the FPN reduced to below background level.'IntroductionPixel sharing becomes most common technology as pixel size of CMOS image sensors is highly scaled down [1]. Recently, 4-pixel sharing such as 4x1 [2,3,4] and 2x2 [5,6,7] are widely used. In particularly 4x1 sharing, it has been observed horizontal line FPN with the period of shared pixels when highlight scene is imaged and integration period is reduced to very short time by electronic shuttering. Figure 1 shows an example of captured image.We have analyzed the phenomena and attributed it to overflow mechanism from other pixels within shared pixels. To suppress this overflow mechanism, we introduced additional shutter operations before original shutter and after readout. Experimental results based on the suppressing method show that the overflow model is proved and the horizontal line FPN is clearly removed.'AnalysisIn 4x1 pixel sharing, pixel circuit is shown in Figure 2 and readout timing is shown in Figure 3. We consider the case that highlight scene is imaged and integration period is reduced to very short time around one horizontal line period (1H) by electronic shuttering. When first line of shared pixels is readout, only first readout photodiode (PD-1) is below saturation and others (PD-2,PD-3 and PD-4) are over saturation. Therefore, overflow current from three photodiodes are continuously injected to detection node (FD). In Figure 3, the overflow current accumulated in CDS period (Tcds) causes additional signal (Vfpn) on CDS output, which is the difference between reset output at Tr and signal output at Ts. Next, when second line of shared pixels is readout, first and second readout photodiodes (PD-1 and PD-2) are below saturation and others (PD-3 and PD-4) are over saturation, because PD-1 is just after the readout. Therefore, additional signal (Vfpn) of second line is smaller than that of first line. In the same way, additional signals of third and forth lines are smaller than that of first and second lines. As the results, horizontal line FPN with the period of shared pixels will appear. Figure 4 shows those phenomena schematically, where (A) is the case that shutter period is 1H and (B) is the case that the shutter period is 2H. When incident light is strong enough to saturate the photodiode below 3H period, overflow occurs soon after readout, which is shown as ∆2 in Figure 4. Figure 5 is a measured signal output along horizontal line numbers.

FPN indicated in Figure 4 is clearly observed.The FPN value is proportional to light intensity Vs, time ratio Tcds/Th and shutter period, where Vs is the signal at 1H integration period and Th is a horizontal line period. At 1H-shutter operation, Vfpn=2(Tcds/Th)(Vs)=2∆1. At 2H-shutter operation, Vfpn=(Tcds/Th)(Vs)=∆1. To reduce the FPN, it is effective to reduce the CDS period (Tcds). But reduction of CDS period brings increase of readout band width, which causes increase of readout noise [8]. A certain CDS period should be maintained.'FPN reduction methodTo suppress this overflow mechanism, we introduced additional shutter operations before original shutter and after readout. Figure 6 shows timing diagram of the operation and expected effect. Before normal shutter operations (S), additional shutter operations (S’) are added in all related lines. As the same manner, after normal readout operations (R), additional shutter operations (S’) are added in all related lines. By introducing additional shutter operations, signal charges in photodiodes before shutter and after readout operations are removed and overflow is ceased. As the results, the FPN disappears.'Results and discussionsFigure 7 shows captured image and Figure 8 shows measured signal pattern when the reduction method is applied. The FPN clearly disappears from captured image and signal waveforms. This also proves the overflow model.The improvement method shown in Figure 6 is easily realized in progressive readout mode, but in interlace or random access readout modes, it needs special care for constructing readout logic. In 2x2 pixel sharing architecture, similar overflow effect may occur (See Figure 9). As FPN is 2x2 mode, it may cause coloring effect in Bayer color filter array. The correcting method shown above is also applicable to this case.'ConclusionsIt was found that horizontal line FPN was observed in vertically shared pixels. The FPN was reduced to below background level by introducing additional shutter operation.References[1] R.D.McGrath, et al., “Shared pixels for CMOS image sensor arrays”, Proceeding of 2005 IEEE Workshop on CCD and AIS, R3,2005.

INPUT PINS: CLK, STB & DINOUTPUT PINS: K1 TO K3OUTPUT PINS: DOUT, GR1 TO GR4OUTPUT PINS: SG1 TO SG11OUTPUT PINS: GR5, GR6 AND SG12/GR7FUNCTION DESCRIPTIONCOMMANDSA command is the first byte (b0 to b7) inputted to PT6961 via the DIN Pin after STB Pin has changed from HIGH to LOW State. If for some reason the STB Pin is set to HIGH while data or commands are being transmitted, the serial communication is initialized, and the data/commands being transmitted are considered invalid.COMMANDS 1: DISPLAY MODE SETTING COMMANDSPT6961 provides 2 display mode settings as shown in the diagram below: As stated earlier a command is the first one byte (b0 to b7) transmitted to PT6961 via the DIN Pin when STB is LOW. However, for these commands, the bit 3 & bit 8 (b2 to b7) are given a value of 0.The Display Mode Setting Commands determine the number of segments and grids to be used (12 to 11 segments, 6 to 7 grids). A display command ON must be executed in order to resume display. If the same mode setting is selected, no command execution is take place, therefore, nothing happens.When Power is turned ON, the 7-grid, 11-segment modes is selected.DisplaySettings:Modesegmentsdigits,12610:11segments7digits,11:COMMANDS 2: DATA SETTING COMMANDSThe Data Setting Commands executes the Data Write or Data Read Modes for PT6961. The dataSetting Command, the bits 5 and 6 (b4, b5) are given the value of 0, bit 7 (b6) is given the value of 1 while bit 8 (b7) is given the value of 0. Please refer to the diagram below.When power is turned ON, bit 4 to bit 1 (b3 to b0) are given the value of 0.ModeSettings:Read&DisplayModetoDataKey(DisplayMode):SettingsModebeenhasWrittenDataAddressafterModeOperationNormal0:Mode1:TestPT6961 KEY MATRIX & KEY INPUT DATA STORAGE RAMPT6961 Key Matrix consists of 10 x 3 array as shown below:Each data entered by each key is stored as follows and read by a READ Command, starting from the last significant bit.

光靠矩阵键盘是无法正确地完成输入工作的,另外还需搭配以下几个电路模块: 1、 时钟产生电路
当一个系统中使用不同操作频率的脉冲波形时,最方便的方法就是利用一个自由计数器 来产生各种频率。本电路中就使用三种不同频率的工作脉冲波形。它们分别是:系统时钟(它 是系统内部所有时钟的提供者,频率最高)、弹跳消除取样信号、键盘扫描信号和七段显示器 扫描信号。在很多的电路设计中,键盘扫描信号和七段显示器扫描信号可以使用相同的时钟 信号,本设计也采用此方法。

微波线性功率放大器综述
1概述
微波线性功率放大器在现代微波(无线)通信系统中的重要性越来越大。

特别是在CDMA 体制移动通信系统中,线性功率放大器已经是必不可少的重要部件。

2基本指标
2.1 AM/AM AM/PM失真
一个HPA的线性特征可以用AM/AM和AM/PM 曲线来表示. 输入的RF 信号可以表示为:
x(t)=R i(t)⨯cos[ω0t+θx(t)] (1)
相应的输出表示为:
y(t)=G[R i(f)] ⨯cos{ω0t+θx(t)+ψ[R i(f)]} (2)
其中G和ψ表示AM/AM 和AM/PM曲线,如图一。

图. 1 实测的放大器失真曲线
理想的线性功放的曲线如图2。

图. 2 理想的放大器AM/AM和AM/PM曲线
2.2 双音IMD 、IP3、P1dB
双音IMD ,在放大器输入端加入两个CW 信号,在放大器的输出端测量的3阶、5阶等信号大小,以dBc 表示。

IP3
IMD 、IP3及P 1dB 定义图示
2.3 ACPR
ACPR 主要应用在象CDMA 这样的宽频谱信号的研究上。

邻道功率(ACP )定义为当主信道加一信号时,紧邻主信道的两个信道内的功率大小。

邻道功率的产生主要来自两个方面,一是由于器件的非线性作用产生,二是由于主信道信号本身频谱较信道宽。

ACPR 定义为ACP 功率与主信道功率的比值。

图3 邻道功率(ACP )定义
图4 器件非线性产生的邻道功率
对移动通信的CDMA 信号而言,其IM3(即ACPR )与IP3的关系可以通过一公式表示。

IP3=-5log[P IM3(f 1,f 2)B 3/P O [(3B-f 1)3-(3B-f 2)3]]+22.2 (dBm)
其中: P IM3(f 1,f 2) 表示要求的IM3的输出功率(W )
B 表示二分之一CDMA 信号带宽 (KHz )
f 1,f 2表示两个边带频率相对于中心频率的差值(KHz )
P O 表示输出功率(W )
2.4 级联线性功放的IM3计算
功率放大器一般由多级放大组成,在设计时需要计算,级联后的IM3。

以下公式是一经验公式。

时间证明其准确性是很高的。

设功放由两级组成,第一级IM3表示为IM3D ,第二级IM3表示为IM3F ,则级联后的IM3表示为:
IM3=IM3F + 20log[1+10(IM3D-IM3F/20)]
多级放大器以次类推。

根据该公式绘制的IM3恶化曲线如下图。

3预失真线性化技术介绍
预失真的线性化技术是各种线性化技术的基础,其它方法是在此基础上进行的更为完善的处理。

然而就原理来说,都没有超越该技术。
