OBJECTIVES: – Describe RTOS support – Identify various RTOSs CONTENT: – 9 pages – 2 questions LEARNING TIME: – 15 minutes Welcome to the module on RTOS support. This module describes what an RTOS is and explains the various levels of support for RTOSs. This module also presents the features of various RTOSs including their level of integration. 1 What is an RTOS? • Real-Time Operating System (RTOS) • Interrupts guaranteed to be handled in a specified time • Not a specific product but a class of operating systems RTOS stands for Real-Time Operating System. It is any operating system where interrupts are guaranteed to be handled within a certain specified, maximum time. This feature makes the system suitable for control of hardware in embedded systems and other time-critical applications. RTOS is not a specific product but a class of operating systems. 2 RTOS Support • OSEKturbo for embedded 8, 16, and 32bit architectures • Tools developed by Third Parties for CodeWarrior – Precise/MQX –RTXC –SMX – TargetOS – Nucleus – OSE RTOS Freescale has support for several different RTOSs, including Linux, OSEKturbo for embedded 8, 16, and 32bit architectures, Precise/MQX from ARC International, RTXC from Quadros, SMX from Micro Digital, TargetOS from Blunk Microsystems, Nucleus from Accelerated Technology, and OSE RTOS. 3 OSEKturbo • OSEKturbo: − Is a highly optimized and scalable embedded RTOS − Is an ideal software platform − Is suitable for performance and real-time determinism − Is available now or currently porting for many platforms OSEKturbo for embedded 8, 16, and 32-bit architectures is a highly optimized and scalable embedded RTOS.

  • Chapter 8 Instruction Set
    Chapter 8 Instruction Set 80 80 This chapter lists the PowerPC instruction set in alphabetical order by mnemonic. Note that each entry includes the instruction formats and a quick reference ‘legend’ that provides such information as the level(s) of the PowerPC architecture in which the instruction may be found—user instruction set architecture (UISA), virtual environment architecture U (VEA), and operating environment architecture (OEA); and the privilege level of the V instruction—user- or supervisor-level (an instruction is assumed to be user-level unless the O legend specifies that it is supervisor-level); and the instruction formats. The format diagrams show, horizontally, all valid combinations of instruction fields; for a graphical representation of these instruction formats, see Appendix A, “PowerPC Instruction Set Listings.” The legend also indicates if the instruction is 64-bit, , 64-bit bridge, and/or optional. A description of the instruction fields and pseudocode conventions are also provided. For more information on the PowerPC instruction set, refer to Chapter 4, “Addressing Modes and Instruction Set Summary.” Note that the architecture specification refers to user-level and supervisor-level as problem state and privileged state, respectively. 8.1 Instruction Formats Instructions are four bytes long and word-aligned, so when instruction addresses are U presented to the processor (as in branch instructions) the two low-order bits are ignored. Similarly, whenever the processor develops an instruction address, its two low-order bits are zero. Bits 0–5 always specify the primary opcode. Many instructions also have an extended opcode. The remaining bits of the instruction contain one or more fields for the different instruction formats.

Received 25 February, 2014; Acceppted 9 June, 2014 Due to premature defoliation, early blight epidemics can cause major yield losses. Large-spore Alternaria species such as A. solani and A. tomatophila have long been recognized as important pathogens responsible for such blight disease in the famiily Solanaceeae and thus represent a serious risk for crop production. Small-spore Alternaria species have also been frequently isolated from plant samples with typical blight symptoms but their incidence as primary pathogens is often controversial. In order to study the diversity of small-spore Alternaria species, 32 isolates were selected from a larger collection of 130 isolates from infected leaves, fruits and sttems of tomato from various growing regions of North-West Algeria. Morphological characterization under standard conditions annd polymerase chain reaction (PCR) analyses using specific primers to amplify a part of the ITS regions and the 5.8S gene were conducted to confirm their identification as members of the altternata section.

  • MPC555 Interrupts by John Dunlop, Josef Fuchs, and Steve Mihalik Rev
    Order this document by: MOTOROLA AN2109/D SEMICONDUCTOR APPLICATION NOTE MPC555 Interrupts by John Dunlop, Josef Fuchs, and Steve Mihalik Rev. 0, 26 July 2001 1 Introduction The MPC555 has numerous timers, peripherals and input pins that can generate interrupts. This appli- cation note describes how the interrupts work and how to write software for their initialization and ser- vice routines. Examples illustrate how interrupt handler routines written in assembler, C and even controlled by an operating system can have a dramatic variation in overhead. This overhead is almost entirely caused by the amount of context, (i.e., registers), saved and restored in the routine. Although this application note focuses on interrupts, the discussion of context saving and restoring ap- plies to other exceptions as well as other Motorola PowerPC™ microcontrollers. In addition, later MPC5xx microprocessors include an enhanced interrupt controller which has features to reduce laten- cy. A summary of these features, which are optional to use in these later microcontrollers is listed in Section Appendix B Enhanced Interrupt Controller Summary. 2 Background 2.1 Interrupts versus Exceptions Definitions of “interrupts” and “exceptions” are not always consistent in PowerPC™ literature. The fol- lowing definitions are used for this application note. Exceptions are events that change normal program flow and machine state. Some examples of excep- tions are reset, decrementer passing zero, system call instruction, various bus access errors, and even a software or hardware debugger. When an exception occurs, a short hardware context switch takes place and the processor branches to an address (exception vector) which is unique for each type of ex- ception.
