  • Fundamentals_of_Global_Positioning_System3

    If one examines the current literature on GPS receiver design, most of it is quite a bit above the level of the novice. It is taken for granted that the reader is already at a fairly high level of understanding and proceeds from there. This text will be an attempt to take the reader through the concepts and circuits needed to be able to understand how a GPS receiver works from the antenna to the solution of user position.

  • An easy way to work with Exter

    Internal Interrupts are used to respond to asynchronous requests from a certain part of themicrocontroller that needs to be serviced. Each peripheral in the TriCore as well as theBus Control Unit, the Debug Unit, the Peripheral Control Processor (PCP) and the CPUitself can generate an Interrupt Request.So what is an external Interrupt?An external Interrupt is something alike as the internal Interrupt. The difference is that anexternal Interrupt request is caused by an external event. Normally this would be a pulseon Port0 or Port1, but it can be even a signal from the input buffer of the SSC, indicatingthat a service is requested.The User’s Manual does not explain this aspect in detail so this ApNote will explain themost common form of an external Interrupt request. This ApNote will show that there is aneasy way to react on a pulse on Port0 or Port1 and to create with this impulse an InterruptService Request. Later in the second part of the document, you can find hints on how todebounce impulses to enable the use of a simple switch as the input device.Note: You will find additional information on how to setup the Interrupt System in theApNote “First steps through the TriCore Interrupt System” (AP3222xx)1. It would gobeyond the scope of this document to explain this here, but you will find selfexplanatoryexamples later on.

  • 基于以太网分布式的数据采集控制系统

    针对飞行模拟器座舱数据采集的复杂性,设计了一种基于以太网分布式的数据采集控制系统,该系统是RCM5700微处理器模块上的以太网应用。在系统的基础上具体讨论了PoE技术的应用,在传输数据的网线上同时提供电流,提出并实现了一种包括辅助电源在内的完整可靠的PoE供电方案。设计采用美国国家半导体的LM5073和LM5576并根据不同的负载情况,进行稳定可靠的电压转换,以满足数据采集电路的要求。实验结果表明:该设计稳定可靠,满足低于13 W的采集节点供电要求,提高了模拟器信号采集系统的通用性和标准化程度,避免了以往数据采集节点单独繁琐的电源设计。 Abstract:  Aiming at the complexity of large avion simulation and controlling,the simulator cabin distribute data collecting and control system was designed. This system is the application of RCM5700 on Ethernet. Based on this system,PoE technique that makes Ethernet can also provide power were expounded with emphasis and included FAUX design the PoE resolution was realized. To achieve the requirement of this system,LM5073 and LM5576 were used to DC-DC switch. From the data of experiment,the design filled the requirement of power-need of node whose power was lower than 13W. The application of the technique can advance the degree of simulation data collections currency and standardization and avoid designing additional power system.

  • 在网络安全中经常会遇到rootkit

    在网络安全中经常会遇到rootkit,NSA安全和入侵检测术语字典( NSA Glossary of Terms Used in Security and Intrusion Detection)对rootkit的定义如下:A hacker security tool that captures passwords and message traffic to and from a computer. A collection of tools that allows a hacker to provide a backdoor into a system, collect information on other systems on the network,mask the fact that the system is compromised, and much more. Rootkit is a classic example of Trojan Horse software. Rootkit is available for a wide range of operating systems.
