This document provides guidelines for integrating a discrete high speed USB host controller onto a fourlayer desktop motherboard. The material covered can be broken into three main categories: Board design guidelines, EMI/ESD guidelines and front panel USB guidelines. Section 1.1 Background provides an explanation of the routing experiments and testing performed to validate the feasibility of 480 Megabits per second on an actual motherboard. Section 7 contains a design checklist that lists each design recommendation described in this document. High speed USB operation is described in the USB 2.0 Specification (http://www.usb.org/developers/docs.html).

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 contains the memtest 8051 firmware for the Anchor Chips EZ-USB chip. The purpose of this software is to test the different memory segments in the Ez-Usb chip. This example will output the string "good" on the 7 segment LED if the mem test passes, or it will output the first address where the memtest fails.

通用串行總線(USB)是一種新興的計算機外圍串行通信接口標準，與常用的計算機接口(如串口、并口等)相比，通用串行總線(Universal Serial Bus，USB)具有熱插拔、即插即用、數(shù)據(jù)傳輸可靠、擴展方便、低成本等優(yōu)點。從問世以來，它得到了廣泛的應用，一方面已成為當前計算機必備的接口之一，同時也被廣泛地應用于嵌入式系統(tǒng)設計中。 從1994年USB 0．7出現(xiàn)開始，USB實施者論壇(Implementation Forum)先后定義了USB 0．8、0．9、1．0、1．1、2．0以及USB OTG等規(guī)范，以及各種不同的設備類規(guī)范。其中USB1．1規(guī)范目前正逐步廣泛應用，而USB2．0和USBOTG作為USB協(xié)議的更新和擴展，也將使USB占領更廣的外設
