Foreword Welcome to the 1.3.1 release of Red Hat eCos(TM) - the Embedded Configurable Operating System. What’s New in 1.3.1? In this, the third major public release of eCos, we have added a wealth of new features, enhancements, and have further extended the target platform coverage. The configuration system has been completely revised and updated. Major new elements include: I Package management that supports the extension of eCos functionality via third party add-on packages. I A standardized configuration save file format that is human readable and editable, and compatible between both GUI and command line configuration tools. I Enhanced web based help and component documentation system integrated into the GUI configuration tool. I The Component Definition Language (CDL) has been radically revised and has now been implemented as a TCL extension for maximum flexibility. CDL is now fully documented in the Component Writers Guide. I Template support for straightforward control of multiple configuration elements, which can be used to provide easy access to standard eCos configurations such as a debug stub boot ROM. I Best of all, the source of the new configuration tools and underlying libCDL technology has been open sourced under the GNU Public License (GPL). A companion beta version of the eCos TCP/IP stack has been released in conjunction with 1.3.1. The stack is derived from the OpenBSD source base and provides UDP, TCP, ICMP and BOOTP protocol support on an IPv4 standards base. Device driver support for Cirrus Logic EP72xx evaluation boards and Motorola MBX is included. The stack, ethernet core support, and device drivers are all distributed as configurable eCos packages. eCos Getting Started with eCos I 7 eCos in a

  • Timing Comparison of the Real-Time Operating Systems for Small Microcontrollers
    S S symmetry Article Timing Comparison of the Real-Time Operating Systems for Small Microcontrollers Ioan Ungurean 1,2 1 Faculty of Electrical Engineering and Computer Science; Stefan cel Mare University of Suceava, 720229 Suceava, Romania; [email protected] 2 MANSiD Integrated Center, Stefan cel Mare University, 720229 Suceava, Romania Received: 9 March 2020; Accepted: 1 April 2020; Published: 8 April 2020 Abstract: In automatic systems used in the control and monitoring of industrial processes, fieldbuses with specific real-time requirements are used. Often, the sensors are connected to these fieldbuses through embedded systems, which also have real-time features specific to the industrial environment in which it operates. The embedded operating systems are very important in the design and development of embedded systems. A distinct class of these operating systems is real-time operating systems (RTOSs) that can be used to develop embedded systems, which have hard and/or soft real-time requirements on small microcontrollers (MCUs). RTOSs offer the basic support for developing embedded systems with applicability in a wide range of fields such as data acquisition, internet of things, data compression, pattern recognition, diversity, similarity, symmetry, and so on. The RTOSs provide basic services for multitasking applications with deterministic behavior on MCUs. The services provided by the RTOSs are task management and inter-task synchronization and communication. The selection of the RTOS is very important in the development of the embedded system with real-time requirements and it must be based on the latency in the handling of the critical operations triggered by internal or external events, predictability/determinism in the execution of the RTOS primitives, license costs, and memory footprint.
