SE-3910 Real-time Systems Week 10, Class 3 Loop jamming CS2852 5/21/2018 SE-3910 Real-time Systems Week 10, Class 3 Loop jamming Class Climate Survey SE3910 Class 5-1 Yoder PPT notes Spring 2014 Print 1-5,11,13-21 Instructor: Print notes Tentative Class Objectives: Explain why writing a file causes a pin to “light” Explain why reading a file reads a 3.3/0V value from a pin Create programs using file I/O Create new capabilities for the GPIO library Create new kernel modules for the BeagleBone? - Because it’s cool - To give deeper hardware/software understanding - To give familiarity with the whole beagle-bone process Explore the Beaglebone OS source code Explain key design decisions made by Beaglebone / Linux OS writers Contrast these decisions with Classic Linux and Windows decisions For HW: Explain the concept of rise time and fall time. Make sketch or figure: Using the oscilloscope, measure the time difference between two signals. Classify events as either being synchronous or asynchronous, periodic, aperiodic, or sporadic Explain the difference between an embedded and non-embedded system Explain the difference between a real-time system and a non-real-time system Identify the key components of the Beaglebone platform Explain why the Beaglebone changes operating frequency under different power conditions Identify the key hardware interfaces of the beaglebone Explain the concept of a cape (daughterboard) Calculate the software GPIO pin number from an expansion port header definition Understand how to read a basic schematic Explain the concept of a dropping resistor Explain the concept of a pull up and a pull down resistor Short the beaglebone’s output to ground Connect the input directly to 5V Connect the input through a resistor to 5V Discuss peak voltage again Potential Topics Piazza Link to Schilling’s PDF Slides Future Quick-quizzes: Labeling voltage, current etc. Why frequency scale? What is the advantage of turning down frequency? HW: How to set frequency to minimize power consumption given full-speed CPU load? (for after scheduling later)Suppose a program blocks X time, and runs Y time while waiting for data, per period. What is the CPU load? Future potential objectives: Discuss two kinds of interrupt systems: Idle main “background” main etc. Identify possible values for hyperperiod and frames in cyclic scheduling Compare and constrast round-robin and cyclic scheduling SE-3910 - Dr. Josiah Yoder Slide style: Dr. Hornick Much Material: Dr. Schilling, Some from Dr. Hornick, etc. Dr. Yoder

What is loop jamming? Aka “loop fusion” Taking two (or more) loops and “jamming” or “fusing” them into a single loop See source https://faculty-web.msoe.edu/yoder/se3910/code/class10_3_LoopJamming/ SE-3910 - Dr. Josiah Yoder Slide style: Dr. Hornick Much Material: Dr. Schilling
