Verilog HDL: Magnitude For a vector (a,b), the magnitude representation is the following: A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ deviCE, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.

Magenta Systems Internet Packet Monitoring Components are a set of Delphi components designed to capture and monitor internet packets using either raw sockets or the WinPcap deviCE driver. Hardware permitting, ethernet packets may be captured and interpreted, and statistics maintained about the traffic. Uses of packet monitoring include totalling internet traffic by IP address and service, monitoring external or internal IP addresses and services accessed, network diagnostics, and many other applications. The component includes two demonstration applications, one that displays raw packets, the other that totals internet traffic. The components include various filters to reduce the number of packets that need to be processed, by allowing specific IP addresses to be ignored, LAN mask to ignore local traffic, and ignore non-IP traffic such as ARP.

RAM Disk Driver with custom BoundsChecker events This sample illustrates how to add custom BoundsChecker events to a DDK driver. It links to the kchecker library and has several BOUNDSCHECKER() calls in it. This sample is a software only Windows NT deviCE Driver. This driver is provided for educational purposes only. Generally the Windows NT cache manager does a much better job of optimizing memory usage than using a RAM disk.

DSP/BIOS Driver Developer Kit 1.11 The DSP/BIOS Driver Developer Kit (DDK) provides a selection of pre-tested DSP/BIOS deviCE drivers, and documentation on how to write a driver to the DSP/BIOS driver model, known as IOM. The DDK includes C source code for all drivers. The DDK 1.11 has been validated with CCS 3.1 and DSP/BIOS 5.20.

This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It permits you to download new code to the deviCE over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after reset. At startup, it waits for a few seconds to see if the downloader is trying to connect. If not, then the bootloader gives up control and jumps to your program. If the downloader is trying to connect, then the bootloader receives the new program over USB and writes it into flash.

This directory builds the Tape class driver for Microsoft® Windows® Server 2003. The class driver implements deviCE-independent support, and exports support routines for deviCE-specific tape miniclass drivers. It handles deviCE-independent tape requests and calls the tape minidriver routines to process deviCE-specific functions. Class driver splits transfer requests, when necessary, to fit the maximum transfer size for the underlying host bus adapter. It also provides deviCE-independent, tape-specific error handling, and calls the tape miniclass driver s deviCE-specific error handling routines.
