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).

A system simulation environment in Matlab/Simulink of RFID is constructed in this paper.
Special attention is emphasized on the analog/RF circuit.Negative effects are concerned in the system
model,such as phase noise of the local oscillator,TX-RX coupling,reflection of the environment,
AWGN noise,DC offset,I/Q mismatch,etc.Performance of the whole system can be evaluated by
changing the coding method,parameters of building blocks,and OPERATION distance.Finally,some
simulation results are presented in this paper.
Jitter is extremely important in systems using PLL-based
clock drivers. The effects of jitter range from not having any
effect on system OPERATION to rendering the system completely
non-functional. This application note provides the reader
with a clear understanding of jitter in high-speed systems. It
introduces the reader to various kinds of jitter in high-speed
systems, their causes and their effects, and methods of reducing
jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.
This demonstration shows that reordering the rows and columns of a sparse matrix S can affect the time and storage required for a matrix OPERATION such as factoring S into its Cholesky decomposition
ST7529液晶驅動 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write OPERATION with no external operating clock to minimize power consumption. In addition, because it contains
power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
