CORDIC (Coordinate Rotation Digital Computer) is a method for computing elementary functions using minimal hardware such as shifts, adds/subs and compares. CORDIC works by rotating the coordinate system through constant angles until the angle is reduces to zero. The angle offsets are selected such that the operations on X and Y are only shifts and adds.

A one-dimensional calibration object consists of three or more collinear points with known relative positions. It is generally believed that a camera can be calibrated only when a 1D calibration object is in planar motion or rotates around a ¯ xed point. In this paper, it is proved that when a multi-camera is observing a 1D object undergoing general rigid motions synchronously, the camera set can be linearly calibrated. A linear algorithm for the camera set calibration is proposed,and then the linear estimation is further re¯ ned using the maximum likelihood criteria. The simulated and real image experiments show that the proposed algorithm is valid and robust.

Mobile phones are constantly decreasing in size, thereby complicating the acoustical functionality. Signal processing methods can be used to partially mitigate this problem. In this paper we suggest a method which uses multiple spectral subtraction functions and two microphones, introducing only a short signal delay.

This driver is based on the 2.6.3 version of drivers/usb/usb-skeleton.c but has been rewritten to be easy to read and use, as no locks are now needed anymore.

2007年最新的多种路径规划算法的仿真软件包。At the later releases more world models and sample planners will be distributed, for now only a few world models and controllers are uploaded within this package. Press Start to start the simulation. Enjoy :) A better tutorial will be prepared soon about using the simulator and adding new algorithms etc.

Hey. This some pid code for the atmega88 that I once used to control a heater. It s purpose is pretty specific, and I only wrote it to work on the mega88, so the code itself won t be too useful. It is a good place to start if you re trying to use or figure out pid though.

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over)

Avalon Interface Specification,The Avalon interface specification is designed to accommodate peripheral development for the system-on-a-programmable-chip (SOPC) environment. The specification provides peripheral designers with a basis for describing the address-based read/write interface found on master and slave peripherals, such as microprocessors, memory, UART, timer, etc.
