NORTi3 is a realtime multitasking operating system conforming to the micro-ITRON 3.0
specification. NORTi3 is divided into two packages: NORTi3 Standard and NORTi3 Extended. The
product NORTi3 Extended has implemented all the system calls of level E placed as "added and
extended functions” in the micro-ITRON specification as well as the system calls equivalent to level X.
he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one period divided by the period. It can also be calculated as the average value during a particular period. That means after low pass filtering, (e.g. RC circuit) the signal becomes analog, with an actual value controlled by the microcontroller. The PWM functionality enables the LPC932 to control for example the speed of DC motors or the brightness of electric lighting.
In this book, we aim to give you an introduction to a wide variety of topics important to you as a developer using UNIX. The word Beginning in the title refers more to the content than to your skill level. We ve structured the book to help you learn more about what UNIX has to offer, however much experience you have already. UNIX programming is a large field and we aim to cover enough about a wide range of topics to give you a good beginning in each subject.

This zip file shows the use ROM Services in order to speed up an application and reduce its code size. It shows how to load a method of the Xmodem service and obtain a first level bootloader. Includes main.html file for help.
Included are the files wav1.m, wav2.m, wavecoef.mat and readme.
wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the well known wavelet transform of the given matrix. Daubechies wavelet coefficients are used for wavelet transform operation wahich is saved in wavcoeff.mat.
This application report introduces and describes an MP3 /AAC audio player for use with the TMS320C54x(TM) digital signal processor (DSP) devices. This audio player is based on Reference Framework Level 3 (RF3). Reference Framework for eXpressDSP(TM) Software is a start-ware for developing applications that use DSP/BIOS(TM) and the TMS320(TM) DSP AlgorithmStandard.
Wavelets have widely been used in many signal and image processing applications. In this paper, a new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is
done using a tree of carry save adders to ensure the high speed processing required for many applications.
The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis
reveals that the proposed architecture, implemented using current VLSI technologies, can process a
video stream in real time.
A program to demonstrate the optimization process of particle swarm optimization. A two-dimensional objective function is visualized by level of grey: the lighter the color, the higher the function value. The particles are shown as red circles, their trajectory as red lines.
