Introduction ? ? The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs new Cortex family. With high performance and power efficiency, it targets a wide variety of mobile and consumer applications including mobile phones, set-top boxes, gaming consoles and automotive navigation/entertainment systems. The Cortex-A8 processor spans a range of performance points depending on the implementation, delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding consumer applications and consuming less than 300mW for low-power mobile devices. This translates into a large increase in processing capability while staying with the power levels of previous generations of mobile devices. Consumer applications will benefit from the reduced heat dissipation and resulting lower packaging and integration costs.

A certification path is an ordered list of certificates starting with a certificate issued by the relying party s trust root, and ending with the target certificate that needs to be validated. Certification path validation procedures are based on the algorithm supplied in ITU-T Recommendation X.509 and further defined in Internet Engineering Task Force (IETF) Request for Comments (RFC) 3280. Certification path processing verifies the binding between the subject distinguished name and/or subject alternative name and the subject public key defined in the target certificate. The binding is limited by constraints, which are specified in the certificates that comprise the path, and inputs that are specified by the relying party. To ensure secure interoperation of PKI-enabled applications, the path validation must be done in accordance with the X.509 and RFC 3280 specifications. This document provides the test assertions and the test cases for testing path validation software against these specifications.

When trying to extract information from SAR images, we need to distinguish two types of image property. The more important is where properties of the scene (e.g., its dielectric constant, its geometry, its motion, etc.) produce effects in the image measurements or examination of the image then can provide information about the scene. The second is generated purely by the system and the signal processing.

你可以使用DOS下的Edit或者Windows的记事本(notepad)等任何文本文件编辑工具创建和修改批处理文件。 bat是dos下的批处理文件 .cmd是nt内核命令行环境的另一种批处理文件 从更广义的角度来看，unix的shell脚本以及其它操作系统甚至应用程序中由外壳进行解释执行的文本，都具有与批处理文件十分相似的作用，而且同样是由专用解释器以行为单位解释执行，这种文本形式更通用的称谓是脚本语言。所以从某个程度分析，batch, unix shell, awk, basic, perl 等脚本语言都是一样的，只不过应用的范围和解释的平台各有不同而已。甚至有些应用程序仍然沿用批处理这一称呼，而其内容和扩展名与dos的批处理却又完全不同。

The Open Radar Data Acquisition (ORDA) subsystem replaces the current WSR-88D Radar Data Acquisition subsystem with improved receiver and signal processing hardware and with improved user interface, signal processing and diagnostics software. This paper will discuss the input data from the digital receiver, the ORDA signal processing, and the data output from the ORDA hardware. Specifications of the ORDA digital receiver will be presented. The paper outlines the critical radar signal processing flow and provides analysis of new spectrum width computations and clutter filtering schemes used in the ORDA system. Where appropriate, ORDA performance enhancements, data quality improvements and reliability and maintenance improvements will be highlighted.
