ImpulseC Codeveloper fft code. This file implements the hardware portion of a 256 sample FFT using a radix-4 algorithm. This implementation demonstrates that results similar to hand-coded HDL can be achieved
using the C language, and without using a low-level style of C code.
Introduction
? ?
The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs
new Cortex family. With high performance and power efficiency, it targets a wide
variety of mobile and consumer applications including mobile phones, set-top boxes,
gaming consoles and automotive navigation/entertainment systems. The Cortex-A8
processor spans a range of performance points depending on the implementation,
delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding
consumer applications and consuming less than 300mW for low-power mobile devices.
This translates into a large increase in processing capability while staying with the
power levels of previous generations of mobile devices. Consumer applications will
benefit from the reduced heat dissipation and resulting lower packaging and integration
costs.
FERRET - a broadcast analysis tool
This tool is designed to demonstrate the problem of "data seapage".
The average machine broadcasts a lot of information about itself
on open networks. This tool captures and organizes this information.
This code is extremely low quality, hacked together in order to
demonstrate the problem at the BlackHat Federal 2007 conference.
Higher quality code should be available around May 2007 on our
website at http://www.erratasec.com.
Exploring C++ uses a series of self–directed lessons to divide C++ into bite–sized chunks that you can digest as rapidly as you can swallow them. The book assumes only a basic understanding of fundamental programming concepts (variables, functions, expressions, statements) and requires no prior knowledge of C or any other particular language. It reduces the usually considerable complexity of C++.
The included lessons allow you to learn by doing, as a participant of an interactive education session. You’ll master each step in a one sitting before you proceed to the next. Author Ray Lischner has designed questions to promote learning new material. And by responding to questions throughout the text, youll be engaged every step of the way.
QualNet
Sensor Networks
Library
QualNet’s new Sensor Networks Library is a much
awaited feature set that supports the IEEE 802.15.4
standard, otherwise known as Zigbee. Zigbee
networks are Wireless Personal Area Networks
(WPANs) that are defi ned by a low data rate,
long battery life, and secure networking. Zigbee
networks support automation and remote control
RS_latch using vhdl,
When using static gates as building blocks, the most fundamental latch is the simple SR latch, where S and R stand for set and reset. It can be constructed from a pair of cross-coupled NOR (Not OR) logic gates. The stored bit is present on the output marked Q.
Normally, in storage mode, the S and R inputs are both low, and feedback maintains the Q and Q outputs in a constant state, with Q the complement of Q. If S (Set) is pulsed high while R is held low, then the Q output is forced high, and stays high when S returns to low similarly, if R (Reset) is pulsed high while S is held low, then the Q output is forced low, and stays low when R returns to low.
While faster processors, larger memory, and powerful graphics are fundamental requirements for workstations, users
are also demanding a low-cost, solution-based approach wrapped around a standards-based technology. The Sun UltraTM
20 Workstation, which leverages the AMD OpteronTM processor with Direct Connect Architecture based on AMD64
technology, provides multiple operating system choices and leading nVidia graphics, delivers a platform that offers
flexibility and performance in a cost-effective package with solutions to benefit customers across the board.
This document explains the pulse compression technique. Why it is required and how can it be used effectively. The pulse compression technique helps to increase the maximum range without sacrificing the range resolution and still the power requirement remains low.
