1 ARM-Architektur Toni Reber Redacom AG, 2560 Nidau

2 Warum ist die ARM Architektur erfolgreich - als Unternehmen - Technologie - Mikrocontroller (embedded)

3 Redacom AG und ARM Redacom ist seit 1988 Keil Distributor Keil gehört seit Oktober 2005 zu ARM Redacom AG ist seit diesem Zeitpunkt Repräsentant und Distributor von ARM Distribution Workshop Schulung User Meeting Fast-Prototyping

4 Warum ist die ARM Architektur Erfolgreich (1) Börsenkurs der letzten 2 Jahre

5 Börsenkurs der letzten 6 Monate Apple und Microsoft Apple Gerüchte Microsoft Lizenzvertrag

6 Warum ist die Arm Architektur erfolgreich (2) Mobile Bereich Energieverbrauch Konzept für Downsizing, Clock, Bus usw. Fortschrittliche 32-Bit RISC Technologie Hohe Rechenleistung Innovative Core Erweiterungen (z.bsp. Cortex M4)

7 Warum ist die Arm Architektur erfolgreich (3) Im Bereich embedded Computing, Mikrocontroller 32-Bit, Technologie, bis 4 GB Speicher adressierbar RISC Architektur Geringer Energieverbrauch Clock skalierbar Peripherie meist abschaltbar Cortex M, integriertes Interrupt Konzept All in one CoreSight Debug Interface

11 CoreSight Debugging früher jetzt ab Fr unter Fr

12 Debug and Trace Adapters ULINK2: Debug + Serial Wire Trace Flash Programming + Run-Control Memory + Breakpoint (access while running) Serial Wire Trace Capturing up to 1Mbit/sec (UART mode) ULINKpro: adds ETM + Streaming Trace Cortex-M processors running up to 200MHz 50MHz JTAG clock speed Serial Wire Trace Capturing up to 100Mbit/sec (Manchester Mode) ETM Trace Capturing up to 800Mbit/sec Virtually un-limited Trace Buffer Streaming Trace allows complete Code Coverage and Performance Analysis

13 Debug and Trace Connectors 20-pin (0.1 ) or 10-pin (0.05 ) Connector Identical Debugging capabilities Support 2 Operating Modes: 20-pin (0.1 ) ARM JTAG 10-pin (0.05 ) Cortex Debug Standard 5-pin JTAG mode (device chaining) Serial CoreSight mode 2-pin Serial Wire Debug (SWD) 1-pin Serial Wire Trace Output (SWO) for Data Trace at minimum system cost 20-pin (0.05 ) Cortex Debug+ETM 20-pin (0.05 ) Debug+ETM Connector Superset of 10-pin 0.05 Connector Adds 4 (trace data) +1 (trace clock) pins for high-speed Data + Instruction Trace in any operating mode (JTAG or SWD) More Information:

14 Features ULINKpro Debug and Trace Unit Debug via JTAG interface for ARM7/9 and Cortex-M Serial Wire Debug (SWD) for Cortex-M Serial Wire Viewer (SWV) data trace for Cortex-M Instruction trace (via ETM) for Cortex-M Data streaming direct to host PC Cortex-M processors running up to 200MHz Connectors: 20-pin 0.10 JTAG 10-pin 0.05 Cortex Debug 20-pin 0.05 Cortex Debug+ETM Performance 50MHz JTAG clock speed 1MB/s memory read/write

15 CoreSight Debug Technology (Cortex-M) Start, Stop, and Single-step User Program Instruction Stream for Code Execution Analysis, Time Profiling, Code Coverage 8 Hardware Breakpoints in User Program On-the-Fly (while User Program runs) read/write access to Variables and Memory Contents Application Trace Information: Debug printf, RTOS nfo, Unit Test, UML Annotation Data Trace or Access Breakpoints for 4 Variables Timing Information PC Sampling, Event Counters, Interrupt Execution JTAG (5-pin) or Serial Wire (2-pin + 1 trace pin) ITM, DWT Output via 1 serial trace data pin (UART or Manchester Mode) ITM, DWT, ETM Output via 4 trace data pins + 1 clock pin Trace (ETM, ITM, DWT) not available on Cortex-M0

16 Code Coverage (ETM) Complete software validation requires code coverage Product liability and industry standards (IEC61508) demand for testing according to State of Science and Technology methodologies ETM enabled devices provide complete instruction stream Non-intrusive - use final, optimized code at full speed Feedback provided directly in the debugger window Source & disassembly view Color-coded details for individual instructions Summary analysis by function or module Log File Support Coverage information can be saved for documentation

17 Instruction Trace (ETM) Execution history of all executed instructions Instruction Trace window displays: cycle count (timing) and assembly code synchronized to the C source code. Instruction Trace is useful to analyze sporadic problems Data corruption by incorrect interrupt/thread protection Incorrect timing caused by interrupt/thread nesting

18 What is Streaming Trace? Trace data transferred in real-time to debug host Capture size only limited by host resources (harddisk) Trace for minutes, hours, or longer Required for full code-coverage and timing analysis Today s workstations can present trace data instantly

19 Hardware Components Range of evaluation boards and debug hardware Verify application running on hardware target ULINK family of USB Adapters Debug and Flash programming JTAG and SWD support Hi-Speed Streaming Trace Evaluation Boards ARM7, ARM9, & Cortex-M3 Luminary, NXP, ST, & Toshiba
