fwknop stands for "Firewall Knock Operator" and is an upcoming piece of software that will be released at the DEFCON 12 conference in July, 2004 in Las Vegas. fwknop implements network access controls (via iptables) based on a flexible port knocking mini-language, but with a twist it combines port knocking and passive operating system fingerprinting to make it possible to do things like only allow, say, Linux-2.4/2.6 systems to connect to your SSH daemon. fwknop supports shared, multi-protocol port knock sequences along with both relative and absolute timeouts, and coded port knock sequences encrypted with the Rijndael block cipher.

程序描述：网络远端温度感测器，这个范例中使用到 （1）8051 的Port 1连接到LCD显示器，PORT 3的P3.3、P3.4和P3.5分别连接到LCD显示器的控制线，程序执行时可以让LCD显示器显示出时间和日期。 （2）温度感测组件AD590经由ADC0804将感测到的温度，转换成数位数据，然后经由PORT 0输入8051。 （3）igangcai 8051的第10和第11只脚RXD和TXD分别连线到MAX232，然后连接到PC的COM埠。 (4) 当PC端经由RS232传送S时，接下来PC送出的下 个byte就用来设定PORT 3的输出。 (5) 当PC端经由RS232传送T时，接下来PC连续送出五个bytes，这五个bytes是 "年月日时分"，这是 PC 用来设定实验板的时间日期。 (6) 8051每 分钟就读入ADC0804转换的数字温度数据，然后通过RS232传送给PC端，再由PC端通过网络传送到远端的电脑。*/

GPS 接收程序 DEMO。 HsGpsDll Library 1.1 A GPS Control/Component for C/C++ HsGpsDll is a Windows Dynamic Link Library which provides access to any NMEA-183 compliant GPS receiver via a serial communications port. HsGpsDll is designed for use from Visual C, Visual Basic or other languages, capable of calling DLL functions. HsGpsDll allows a user application to read from a GPS device the current GPS position fix, velocity over ground (speed in kilometers per hour), plus number of of sattelites in view, current altitude (against mean sea level) and UTC date and time

ECE345, Visual-to-Audio Electronic Travel Aid Code for TM320C54x (v2a.asm) download This project involves the design and implementation of a audio synthesis device that converts moving images into audio signals. The system is built on a TM320C54x DSP with interface to an IMAQ camera module via the serial port on a PC. Brief description: A LabVIEW VI acquires an image from the IMAQ camera module. It quantizes the image into a 5x5, 3-bit image, and sends the data to the TM320C54x DSP via a serial port. The TM320C54x DSP constructs a 64-tap FIR by combining a series of 64-tap head related transfer functions (HRTF) according to the incoming data, and then filters an input audio signal with this FIR filter, in effect creating a correspondence between the filtered signal and the original image.

In term project, we will take the baseline JPEG codec in ARM-based platform system as an example to practice the design flow in SoC. We divide the project into three parts, and the goal of each part is described as follow. Part I: Design a baseline JPEG software codec in C/C++ and port it to ARM core,(ARM7TDMI, ARM720T, or ARM922T.) Part II: Make use of virtual prototype to integrate/verify the hardware and software. Part III: Verify your soft IP in target environment.
