Sofia-SIP is an open-source SIP User-Agent library, compliant
with the IETF RFC3261 specification. It can be used as
a building block for SIP client software for uses such as VoIP,
IM, and many other Real-Time and person-to-person communication
services. The primary target platform for Sofia-SIP is
GNU/Linux.
Qpsk signal Processing Code
The DSP code should be efficient and accurate to properly demodulate the incoming signal. The DSP can be coded strictly in “C” or C-language can be intermingled with assembly code.include

the geometry of a diffraction grating, a common
illustration in textbooks of optics, spectroscopy, and analytical chemistry.
Sliders on the figures allow Real-Time interactive control of the incidence angle,
grating ruling density (lines/mm), wavelength, and diffraction order.
The download includes the kernel source code, and a demo application for EVERY
RTOS port. See http://www.freertos.org/a00017.html for full details of the
directory structure and information on locating the files you require.
The easiest way to use FreeRTOS is start start with one of the demo application
projects. Once this is running the project can be modified to include your own
source files. This way the correct files and compiler options will be
automatically included in your application.
+ The Source directory contains the real time kernel source files for every
port. The kernel itself is only 3 files.
+ The Demo directory contains the demo application source files for every
port.
+ The TraceCon directory contains the trace visualisation exe file.
See the readme files in the respective directories for further information.

In this paper we describe a control methodology for
catching a fast moving object with a robot manipulator,
where visual information is employed to track the
trajectory of the target. Sensing, planning and control
are performed in Real-Time to cope with possible
unpredictable trajectory changes of the moving target,
and prediction techniques are adopted to compensate the
time delays introduced by visual processing and by the
robot controller. A simple but reliable model of the
robot controller has been taken into account in the
control architecture for improving the performance of the
system. Experimental results have shown that the robot
system is capable of tracking and catching an object
moving on a plane at velocities of up to 700 mm/s and
accelerations of up to 1500 mm/s2.
The sample software includes, common library, peripheral APIs, and test modules
for the APIs. The common library include startup file, standard definition and
header files, processor specific setup module, generic interrupt related APIs,
timer routine, and scatter loading file. The peripheral directories include,
GPIO, PWM, Real-Time clock, timer, SPI, I2C, Watchdog timer, UART, external
interrupt, etc.
