Bootloading the TMS320VC5506/C5507/C5509 A digital signal processor (DSP)
through the on-chip universal serial bus (USB) peripheral is part of the standard
bootloader provided on the device. This document describes the procedures for
physically connecting the DSP to a USB host, invoking the USB bootloader on the
DSP, generating the correct boot table file, and downloading the boot table from the
host to the DSP via USB.
This paper presents a novel technique to increase
the quality of medical images based on Histogram
Equalization. In the proposed method first we have
applied a noise reduction method and then we apply
some suitable preprocessing on histogram of the
medical images and after that histogram equalization
has been applied on the new histogram. Our proposed
method in despite of its simplicity has better results in
compare to other usual methods based on histogram
equalization. The quality of resulted images after
applying our proposed methods has been tested on a
database (medical images) with a confirmed criterion
by viewer. Also we have considered a mathematical
criterion for comparing our proposed algorithm with
other available methods for contrast enhancement.
Results show the better efficiency of the proposed
method.
A fourier filter for time-series signals. Does not
require the Signal Processing Toolbox.
There is an interactive version with sliders that
allow you to adjust the filter parameters
continuously while observing the effect on your signal
dynamically.
Interactive smoothing for time-series signals, with sliders that
allow you to adjust the smoothing parameters continuously
while observing the effect on your signal dynamically. Run
SmoothSliderTest to see how it works.
Video-DVM is a very cheap DVM that shows how an output as complex as a videocomposite signal can be generated entirely in software: two I/O pins and three resistors are all the hardware required. Connected to any TV set it displays voltages, included max and min peaks, using both giant digits and an analog bar-display . A serial data output for computer data logging is provided, too.
C Algorithms for Real-Time DSP
Chapters 1 and 2 cover the basic principles of digital signal processing and C programming. Readers familiar with these topics may wish to skip one or both chapters.
This file is a function under matlab which allow to compute and plot fast fourier transform of a signal. We can observe the effect of the signal parameter can be changed such as frequency and N points.
This file is a function under matlab which allow to compute several statistical parameter of random signal such as variance, power, mean values, std, ...
NN Functions
a program in Lisp to demonstrate working of an artificial neuron. (Enter an input vector X and weight vector W. Calculate weighted sum XW. Transform this using signal or activation functions like logistic, threshold, hyperbolic-tangent, linear, exponential, sigmoid or some other functions (syntax provided) and display the output).
