隨著存儲技術的迅速發展，存儲業務需求的不斷增長，獨立的磁盤冗余陣列可利用多個磁盤并行存取提高存儲系統的性能。磁盤陣列技術采用硬件和軟件兩種方式實現，軟件RAID（Redundant Array of INdependent Disks）主要利用操作系統提供的軟件實現磁盤冗余陣列功能，對系統資源利用率高，節省成本。硬件RAID將大部分RAID功能集成到一塊硬件控制器中，系統資源占用率低，可移植性好。 分析了軟件RAID的性能瓶頸，使用硬件直接完成部分計算提高軟件RAID性能。針對RAID5采用FPGA（Field Programmable Gate Array）技術實現RAID控制器硬件設計，完成磁盤陣列啟動、數據緩存（Cache）以及數據XOR校驗等功能。基于硬件RAID的理論，提出一種基于Virtex-4的硬件RAID控制器的系統設計方案：獨立微處理器和較大容量的內存；實現RAID級別遷移，在線容量擴展，在線數據熱備份等高效、用戶可定制的高級RAID功能；利用Virtex-4內置硬PowerPC完成RAID服務器部分配置和管理工作，運行Linux操作系統、RAID管理軟件等。控制器既可以作為RAID控制卡在服務器上使用，也可作為一個獨立的系統，成為磁盤陣列的調試平臺。 隨著集成電路的發展，芯片的體積越來越小，電路的布局布線密度越來越大，信號的工作頻率也越來越高，高速電路的傳輸線效應和信號完整性問題越來越明顯。RAID控制器屬于高速電路的范疇，在印刷電路板（Printed Circuit Block, PCB）實現時分別從疊層設計、布局、電源完整性、阻抗匹配和串擾等方面考慮了信號完整性問題，并基于IBIS（I/O Buffer Information Specification）模型進行了信號完整性分析及仿真。

Abstract: A perfect voltage reference produces a stable voltage INdependent of any external factors. Real-world voltagereferences, of course, are subject to errors caused by many external factors. One causeof these major errors istemperature. Without care, it is easy to operate a voltage reference outside its operating temperature range. Thisapplication note describes how references respond to temperature changes, and how self-heating can cause a voltagereference to operate outside its recommended temperature range. Once understood, this knowledge can then be used toavoid making this design error.

The LT®6552 is a specialized dual-differencing 75MHzoperational amplifier ideal for rejecting common modenoise as a video line receiver. The input pairs are designedto operate with equal but opposite large-signal differencesand provide exceptional high frequency commonmode rejection (CMRR of 65dB at 10MHz), therebyforming an extremely versatile gain block structure thatminimizes component count in most situations. The dualinput pairs are free to take on INdependent common modelevels, while the two voltage differentials are summedinternally to form a net input signal.

為了改變目前電網現場作業管理的變電巡檢、變電檢修試驗、輸電線路巡檢檢修等管理系統各自獨立運行，信息不能共享，功能、效率受限，建設和維護成本高的現狀，提出了采用B/S+C/S構架模式，將各現場作業管理模塊和生產MIS（管理系統）集成為一體的現場作業管理系統的設計方案，做到各子系統和生產MIS軟硬資源共享，做到同一數據唯一入口、一處錄入多處使用。各子系統設備人員等基礎信息來源于生產管理系統，各子系統又是生產管理系統的作業數據、缺陷信息的重要來源。經過研究試用成功和推廣應用，目前該系統已在江西電網220 kV及以上變電站全面應用。 Abstract: In order to improve the status that the substation field inspection system， substation equipments maintenance and testing system， power-line inspection and maintenance system are running INdependent with each other.

為降低成本和解決現有膜片鉗放大器系統中PC機的干擾問題，研究了一種基于單片機的膜片鉗放大器小系統。該系統采用ADI公司生產的ADuC841作為控制核心，并且配置相應的液晶顯示模塊LCM3202401。模擬電路部分采用高輸入阻抗的AD8627實現微電流信號的采集，并由后級電路進行信號的放大和電阻電容的補償。它具有硬件電路簡單、體積小、使用方便的特點。既可以單獨作為小系統實現采集和顯示，也可以通過紅外方式和PC機進行通訊，在PC機上進行信號的處理。 Abstract: In order to reduce cost and resolve the interferential problem with PC in existing patch clamp amplifiers, a small patch clamp amplifier system design based on microcontroller is studied. It adopts a new high performance microconverter ADuC841 by the ADI as the control core in the system, configuring a liquid crystal module LCM3202401. In the analog circuit, AD8627 with high input impedance is used to detect the low current，signal magnification, as well as resistance and capacitance compensation are accomplished by subsequent circuits. It has the advantage of simple hardware circuit design, small volume and convenient operation. It can either be used as an INdependent system to measure and show signal detected or transmit to PC by infrared ray.

The μPSD32xx family, from ST, consists of Flash programmable system devices with a 8032 MicrocontrollerCore. Of these, the μPSD3234A and μPSD3254A are notable for having a complete implementationof the USB hardware directly on the chip, complying with the Universal Serial Bus Specification, Revision1.1.This application note describes a demonstration program that has been written for the DK3200 hardwaredemonstration kit (incorporating a μPSD3234A device). It gives the user an idea of how simple it is to workwith the device, using the HID class as a ready-made device driver for the USB connection.IN-APPLICATION-PROGRAMMING (IAP) AND IN-SYSTEM-PROGRAMMING (ISP)Since the μPSD contains two INdependent Flash memory arrays, the Micro Controller Unit (MCU) can executecode from one memory while erasing and programming the other. Product firmware updates in thefield can be reliably performed over any communication channel (such as CAN, Ethernet, UART, J1850)using this unique architecture. For In-Application-Programming (IAP), all code is updated through theMCU. The main advantage for the user is that the firmware can be updated remotely. The target applicationruns and takes care on its own program code and data memory.IAP is not the only method to program the firmware in μPSD devices. They can also be programmed usingIn-System-Programming (ISP). A IEEE1149.1-compliant JTAG interface is included on the μPSD. Withthis, the entire device can be rapidly programmed while soldered to the circuit board (Main Flash memory,Secondary Boot Flash memory, the PLD, and all configuration areas). This requires no MCU participation.The MCU is completely bypassed. So, the μPSD can be programmed or reprogrammed any time, anywhere, even when completely uncommitted.Both methods take place with the device in its normal hardware environment, soldered to a printed circuitboard. The IAP method cannot be used without previous use of ISP, because IAP utilizes a small amountof resident code to receive the service commands, and to perform the desired operations.
