Themenschwerpunkte

  • Tools Installation and Introduction
    • Step-by-step installation guide of Byte Craft's eTPU Compiler and ASH WARE's eTPU Stand-Alone Simulator.
    • Brief tour of Simulator including stepping, breakpoints, examining trace data, measuring pulse widths using logic analyzer.
    • Brief tour of Compiler including compiling, project files, multi-file builds, and library directory.
    • Exercise (student will modify some eTPU code to perform a calculation, compile, load into simulator and verify calculation).
  • Channel Hardware Basics
    • "C-centric" introduction to fundamental channel hardware concepts.
    • Sampling input pin state versus detection of an edge and recording the time at which that edge occured.
    • Forcing an output pin to a state versus scheduling a output pin edge to occur at a particular future point in time.
  • Events and Event Handling
    • Using the eTPU compiler to create an event vector table.
    • Examine event and thread response timing diagrams to see where event servicing occurs.
  • Channel Hardware Details
    • Step through each of the fields used to program the channel hardware.
    • Step-by-step guide to setting up matches and transition detection.
  • The Programming Model
    • Emphasis on context and thread issues.
    • Key data type, function variables, explained in detail including memory map.
  • Scheduler
    • Round robin scheduler algorithm.
    • Calculating worst case latency.
    • Statistical latency analyses using post processing trace-dump files.
  • Channel Hardware Modes
    • Explain details of match/transition and action unit 1/2 using the channel "mode".
  • Angle Mode
  • Basic Tools Issues
    • Automated testing using the Simulator, including data flow, behaviour verification, and code coverage.
    • Auto-code generation in the Compiler solves two-copy problem.
    • Example host-side drivers with auto-code generated from the Compiler.

Voraussetzungen
