4 ARM Compiler 5 Robustness and efficiency built on decades investment The reference compiler for the ARM architecture Bare-metal C/C++ compiler for pre-armv8 architectures Leading ecosystem including RTOS, middleware and tools Best code size/performance balance Co-developed with ARM processors Earliest support for new processor features Vectorizing compiler delivers up to 3x improvement using NEON 130% 120% 110% RVDS 100% % 80% Performance Codesize RVDS 3.1 RVDS 4.0 DS-5 Minimizing risk Accurate, reliable code generation for over 20+ years Option for safety functional qualification kit Extended and long-term maintenance options ARM proprietary license (GPL-free) 4

5 ARM Compiler 6 The next generation compiler for ARM processors Based on modern compiler framework Clang/LLVM Framework for collaboration with partners Modern architecture with potential for faster optimization work Support for ARMv8 instruction sets AARCH32/AARCH64 (Ultimate Edition) Roadmap for further optimizations on ARMv8, as well as ARMv7-A/R/M support Much more than open source compiler Bare metal assembler, linker and librarian Industry-leading embedded C and C++ libraries Early access support for new processors and architectures Support and maintenance services 5

6 Linaro GCC Toolchain Integrated and validated compilation toolchain for Linux Fuzz-free code generation for Linux kernel and applications Fully integrated, ready-to-use toolchain Optimized for ARM application processors up to ARMv8-A Compatible with DS-5 Debugger and Streamline Or use your own GNU compilation toolchain DS-5 allows installation and use of other version of GCC to suit your requirements 6

7 DS-5 Key Components Compilation Tools ARM Compiler 5 and 6 C/C++ toolchains for bare-metal and RTOS Integrated Linaro GCC for ARM Linux DS-5 Debugger Comprehensive device bring-up tools and s/w debugger for single- and multi-core platforms OS aware debug, on silicon, virtual platform and emulator Streamline Analyzer CPU, GPU, interconnect performance and power analysis Time- and event-based profiling DS-5 IDE Powerful, customized editor based on industry standard Eclipse IDE 4.3 Hundreds of compatible plugins 7

8 Flexible Architecture Adapts to the complexity of new SoCs, and enables third parties to support debug and trace on their IP Remote Device Debug Interface Connect 3 rd party debuggers to the target via DSTREAM Debuggers & Trace Consumers DS-5 Debugger RDDI Debug & Trace Services Layer (DTSL) CoreSight IP configuration, debug multiplexing, and trace demultiplexing. Python scripts RDDI Template Development Kit Support 3 rd party IP debug via DSTREAM Third Party Debugger Third Party Trace Consumer RDDI Socket to configure: CoreSight IP Pin muxing Resets Trace fabric JTAG 8

9 DS-5 Debugger Engineered to accelerate software deployment on ARM Eclipse GUI CLI Intuitive graphical interface Familiar GDB-like command line i/f Scripting OS Awareness Device Configuration Database Advanced scripting using Jython language Command line scripting with triggering from events Built-in support for Linux, Android and popular RTOSs Task-aware debug and visibility into OS data Supports UP, AMP, SMP, and ARM big.little technology Extensive list of pre-configured devices Stop-mode Run-mode Trace Stop-mode and bidirectional native apps debug Non-intrusive program and system trace Target Connection DSTREAM and compatible probes Supports virtual platforms and emulators 9

10 Leading IP Support in DS-5 Debugger ARMv8 processors Hypervisor and secure OS AMP, SMP, b.l and multi-cluster Flexible cross-trigger configuration Direct memory access via the DAP 10

11 ARM CoreSight Trace Support Follow your program execution step-by-step Advantages of CoreSight trace support in DS-5 Zero-overhead ETM/PTM execution trace Trace - source code matching Instruction-based profile summary Support for cycle accurate and system-wide timestamps Trace triggering and filtering for buffer preservation Log view for No/low intrusiveness instrumentation via ITM or STM Stores up to 4GB of compressed trace in a DSTREAM unit Up to 16-bit parallel trace with DSTREAM 11

12 Device Support Configuration Database Out of the box support for 70+ ARM -based device families Simple selection of platform and operation SoC Bring-up and Config CoreSight Access Tool (CSAT) Bring-up and functional validation of debug and trace infrastructure Platform Configuration Editor Auto-detection of ARM IP for custom or non-supported devices See full list on ds.arm.com/supported-devices/ 12
