This document presents design techniques and reference circuits that power Virtex™-4 FXRocketIO™ multi-gigabit transceivers (MGTs) operating at data rates below 3.125 Gb/s.When using multiple transceivers, it is sometimes preferred to power them from a switchingpower supply. However, switching power supplies generate noise that affects transceiver

For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-stage charging schemes. The majority of batterycharger ICs available today lock the user into one fixedcharging regimen, with at best a limited number ofcustomization options to suit a variety of application needsor battery types. The LTC®1325 addresses these shortcomingsby providing the user with all the functionalblocks needed to implement a simple but highly flexiblebattery charger (see Figure 1) which not only addressesthe issue of charging batteries but also those of batteryconditioning and capacity monitoring.

摘要 本研究計劃之目的，在整合應用以ARM為基礎的嵌入式多媒體實時操作系統于H.264/MPEG-4多媒體上。由于H.264是一種因應實時系統(RTOS)所設計的可擴展性串流傳輸(scalability stream media communication)的編碼技術。H.264主要架構于細細?？蓴U展(Fine Granula Scalability,FGS)的壓縮編碼機制。細粒度可擴展壓縮編碼技術是最新MPEG-4串流式傳輸標準，能依頻寛的差異來調整傳輸的方式。細粒度擴展縮編碼技術以編入可選擇性的增強層(enhanced layers)于碼中，來提高影像傳輸的質量。本計劃主要在于設計一種簡單有效的實時階層可擴展的影像傳輸系統。在增強層編碼及H.264的基本層(base layer)編碼上使用漸進的細粒度可擴展編碼(Progressive Fine Granularity Scalable,PFGS)能直接使用H.264的格式特色來實現FGS。同時加入了LB-LLF(Layer-Based Least-Laxity-Fir stscheduling algorithm)的排程算法，來增 進網路傳輸影像的質量。由實驗結果顯示本系統在串流影像質量PSNR值上確有較佳的效能。
