This paper shows the development of a 1024-point radix-4 FFT VHDL core for applications in hardware signal processing, targeting low-cost FPGA technologies. The developed core is targeted into a Xilinx廬 Spartan鈩?3 XC3S200 FPGA with the inclusion of a VGA display interface and an external 16-bit data acquisition system for performance evaluation purposes. Several tests were performed in order to verify FFT core FUNCTIONALITY, besides the time performance analysis highlights the core advantages over commercially available DSPs and Pentium-based PCs. The core is compared with similar third party IP cores targeting resourceful FPGA technologies. The novelty of this work is to provide a lowcost, resource efficient core for spectrum analysis applications.

Mac OS X for Java Geeks delivers a complete and detailed look at the Mac OS X platform, geared specifically at Java developers. Programmers using the 10.2 (Jaguar) release of Mac OS X, and the new JDK 1.4, have unprecedented new FUNCTIONALITY available to them. Whether you are a Java newbie, working your way through Java Swing and classpath issues, or you are a Java guru, comfortable with digital media, reflection, and J2EE, this book will teach you how to get around on Mac OS X. You ll also get the latest information on how to build applications that run seamlessly, and identically, on Windows, Linux, Unix, and the Mac.

This is a device for use by RC hobbysts: it transforms a servo from proportional to integrative. For RC boats, it allows user not to change the FUNCTIONALITY of the throttle stick, UP/DOWN in stead of proportional. The archive contains also the PCB files.

This file is distributed in the hope that it will be useful, but WITHOUT WARRANTY OF ANY KIND. Author(s): Ole Saether DESCRIPTION: This example should be used together with ex2a-tx433.asm. One nRF9E5 evaluation board (receiver) should be programmed with the hex-file generated from assembling this file and the other evaluation board (transmitter) programmed with the hex-file generated from assembling ex2a-tx433.asm. All switches on the DIP-swith S206 on the receiver must be set to the "on" position and all switches on the DIP-swith S205 on the transmitter must be set to the "on" position. When one of the switched SW1-SW4 on the transmitter is pressed the corresponding LED on the receiver is turned on. The FUNCTIONALITY is the same as in ex2c-rx.c.

The i-mode service by NTT DoCoMo is a mobile phone service in Japan that provides its customers with both voice and comprehensive data services. With an i-mode phone, users can exchange i-mode e-mail and obtain information from i-mode menu sites and i-mode compatible Internet sites. The i-mode phone contains a browser that displays i-mode compatible HTML web pages. Beginning with the 505i phones, you can view Macromedia Flash Lite movies from the i-mode browser. You can also use the phones’ My Picture and Standby Screen applications to view Flash Lite movies. Although a number of manufacturers produce 505i phones, all of them support the same Flash Lite FUNCTIONALITY.
