  • Software Techniques for Improving Microcontrollers EMC Performance
    AN1015 Application note Software techniques for improving microcontrollers EMC performance Introduction A major contributor to improved EMC performance in microcontroller-based electronics systems is the design of hardened software. Problems induced by EMC disturbances need to be considered as early as possible in the design phase. EMC-oriented software increases the security and the reliability of your application. EMC-hardened software is inexpensive to implement, improves the final goods immunity performance and saves hardware and development costs. You should consider EMC disturbances to analog or digital data just like any other application parameter. Examples of problems induced by EMC disturbances: Microcontroller not responding Program Counter runaway Execution of unexpected instructions Bad address pointing Bad execution of subroutines Parasitic reset and/or parasitic interrupts Corruption of IP configuration I/O deprogramming Examples of consequences of failing software: Unexpected response of product Loss of context Unexpected branch in process Loss of interrupts Loss of data integrity Corrupted reading of input values. This application note deals with two categories of software techniques, namely: Preventive techniques: these can be implemented in existing designs, their purpose is to improve product robustness. Auto-recovery techniques: when a runaway condition is detected, a recovery subroutine is used to take the decision to execute fail-safe routines, optionally sending a warning and then automatically returning back to normal operations (this operation may be absolutely transparent to the user of the application).

İzmir Institute of Technology Embedded Systems Lab Role of the Kernel İzmir Institute of Technology Embedded Systems Lab Three Kernel Functions OS Kernel - 3 functions: z Task Scheduler : To determine which task will run next in a multitasking system z Task Dispatcher: To perform necessary bookkeeping to start a task z Intertask Communication: To support communication between one process (i.e. task) and another İzmir Institute of Technology Embedded Systems Lab Kernel Design Strategies z Polled Loop Systems z Cyclic Executive z Cooperative Multitasking z Interrupt-Driven Systems z Foreground/Background Systems z Full featured RTOS İzmir Institute of Technology Embedded Systems Lab 1. Polled Loop Systems Polled loops are used for fast response to single devices. In a polled-loop system, a single and a repetitive instruction is used to test a flag that indicates whether or not some event has occurred. If the event has not occurred, then the polling continues. Example: suppose a software system is needed to handle packets of data that arrive at a rate of no more than 1 per second. A flag named packet_here is set by the network, which writes the data into the CPU’s memory via direct memory access (DMA).

Selecting a fault tolerant technique is not trivial, whereas more than the necessary overhead is usually inserted during the system design. To avoid over-designing, it is necessary to in-depth understand the available design options. However, an exhaustive listing is neither possible to create nor efficient to use due to its prohibited size.

  • Architecure of the Linux Watchdog Software for the Ip Pbx
    U.P.B. Sci. Bull., Series C, Vol. 73, Iss. 4, 2011 ISSN 1454-234x ARCHITECURE OF THE LINUX WATCHDOG SOFTWARE FOR THE IP PBX Mihai Constantin1 În această lucrare sunt proiectate propunerile de arhitectură referitoare la software-ul de Watchdog pentru monitorizarea unui IP PBX. IP PBX conţine două aplicaţii principale care interacţionează între ele: Common Media Server şi IpSmallOfice. Common Media Server oferă capabilităţile de codec VoIP, iar IPSmallOffice, aplicaţia principală care rulează pe Linux PC, controlează apelurile telefonice şi oferă telefonie IP. Watchdog reprezintă o aplicaţie de sine stătătoare şi necesită un fişier de configurare care să citească date despre procesele pe care le monitorizează. De asemenea, această aplicaţie rulează ca „daemon” şi este pornită la startup-ul întregului sistem IP PBX. The architecture proposals of a Watchdog software for the IP PBX monitoring are designed in this paper. IP PBX contains two main applications which interact between them: Common Media Server and IpSmallOffice. Common Media Server provides VoIP codec capabilities, and IpSmallOffice is the main application running on a Linux PC, controls the phone calls and provides IP telephony switching. The Watchdog is a stand-alone application and it needs a configuration file to read the data about the processes it monitors. Moreover, this application will be demonized and is added to start at system startup. Keywords: Watchdog, Common Media Server, IpSmallOffice,Linux, Processes,Polling,SIP,Keepalives 1. Introduction IPSmallOffice and Common Media Server are interdependent applications. Given this, when one of them is shutdown or, in a worse case, crashes, both of them need to be restarted.

  • Great Watchdogs Version 1.2, Updated January 2004
    Great Watchdogs Version 1.2, updated January 2004 Jack G. Ganssle [email protected] The Ganssle Group PO Box 38346 Baltimore, MD 21231 (410) 496-3647 fax (647) 439-1454 Jack Ganssle believes that embedded development can be much more efficient than it usually is, and that we can – and must – create more reliable products. He conducts one-day seminars that teach ways to produce better firmware faster. For more information see www.ganssle.com. Building a Great Watchdog Launched in January of 1994, the Clementine spacecraft spent two very successful months mapping the moon before leaving lunar orbit to head towards near-Earth asteroid Geographos. A dual-processor Honeywell 1750 system handled telemetry and various spacecraft functions. Though the 1750 could control Clementine’s thrusters, it did so only in emergency situations; all routine thruster operations were under ground control. On May 7, 1994, the 1750 experienced a floating point exception. This wasn’t unusual; some 3000 prior exceptions had been detected and handled properly. But immediately after the May 7 event downlinked data started varying wildly and nonsensically. Then the data froze. Controllers spent 20 minutes trying to bring the system back to life by sending software resets to the 1750; all were ignored. A hardware reset command finally brought Clementine back on-line. Alive, yes, even communicating with the ground, but with virtually no fuel left. The evidence suggests that the 1750 locked up, probably due to a software crash. While hung the processor turned on one or more thrusters, dumping fuel and setting the spacecraft spinning at 80 RPM.

    Embedded system - Wikipedia, the free encyclopedia 페이지 1 / 10 Embedded system From Wikipedia, the free encyclopedia An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions,[1] often with real-time computing constraints. It is usually embedded as part of a complete device including hardware and mechanical parts. In contrast, a general- purpose computer, such as a personal computer, can do many different tasks depending on programming. Embedded systems control many of the common devices in use today. Since the embedded system is dedicated to specific tasks, design engineers can optimize it, Picture of the internals of a Netgear ADSL reducing the size and cost of the product, or modem/router. A modern example of an embedded increasing the reliability and performance. Some system. Labelled parts include a microprocessor (4), embedded systems are mass-produced, RAM (6), and flash memory (7). benefiting from economies of scale. Physically, embedded systems range from portable devices such as digital watches and MP3 players, to large stationary installations like traffic lights, factory controllers, or the systems controlling nuclear power plants. Complexity varies from low, with a single microcontroller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or enclosure. In general, "embedded system" is not an exactly defined term, as many systems have some element of programmability. For example, Handheld computers share some elements with embedded systems — such as the operating systems and microprocessors which power them — but are not truly embedded systems, because they allow different applications to be loaded and peripherals to be connected.
