DS-5开发工具5.14版本更新 (build 1702 2013/03/26)

更新内容:

ARM Compiler
  • updated to ARM Compiler 5.03 for latest enhancements and bug fixes:
    • improved performance on well-formed loops and switch-based FSMs
    • new loop optimizations, enabled with --loop_optimization_level=2
    • for further information on features and improvements see: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.arn0005j/index.html
ARM Streamline Performance Analyzer
  • new live view added to show performance data as it is being captured
  • Timeline view displays individual kernel threads under the kernel process
  • Timeline view allows easy restoration of auto-generated charts via the snippets menu
  • includes gator version 13
  • gator adds support for monitoring the performance of CoreLink CCI-400 (Cache Coherent Interconnect)
  • gator adds support for environmental data such as temperature, voltage, power and energy within the Linux kernel via the hwmon interface
  • gator adds support for capturing counters from clusters independently in a big.LITTLE system
DS-5 Debugger
  • added OS awareness for Keil CMSIS-RTOS RTX on Cortex-M and Cortex-A9 devices
  • added OS awareness for Freescale MQX RTOS on ARM processor-based Freescale devices
  • trace displays can be time-correlated within the debugger and with external tools
  • support is provided for displaying the CoreSight Global Timestamp unit
  • instruction and data trace from ETMv4 devices (such as Cortex-R7) is now supported
  • Altera USB-Blaster is supported as a connection mechanism to Altera Arria V SoC and Cyclone V SoC boards
  • context menu in the Debug Control and Trace views allows editing DTSL (Debug and Trace Services Layer) options during a debug session
  • new command set/show dtsl-options can be used to access DTSL options during a debug session
  • new command set/show trust-ro-sections-for-opcodes controls whether trace and disassembly can rely on data from read-only sections within any images that are loaded
  • device support extended to include: Altera Arria V SoC, Altera Cyclone V SoC and Atmel ATSAMA5D3x
DSTREAM/RVI
  • new 4.11.0 version of firmware included
  • Cortex-A50 series support now also includes support for Cortex-A53
  • stepping speed on Cortex-A cores is improved
  • SWD connections are supported over 38-pin Mictor connector and ARM and TI 14-pin JTAG connectors
Examples
  • new Jython script jython_pmu to demonstrate use of the Performance Monitor Unit (PMU) to count elapsed cycles and user-defined events
  • source code and examples for a Cortex-A9 port of Keil CMSIS-RTOS RTX are included in CMSIS_RTOS_RTX.zip


以下内容在以后的版本中会逐渐删除:

    Simulation models
    • Cortex-A8 simulation model for Emulation Baseboard is deprecated
    Supported host platforms
    • support for Ubuntu Desktop Edition 10.04 LTS is deprecated
    GCC Toolchain
    • GCC toolchain for Linux applications is removed (see the Compilers section in the release notes for information about installing GCC separately
    以下内容v5.14版本已经删除:
      Examples
      • Linux application examples cpp, cpp_library, cppex, cppex_library and example_library are removed
      • BeagleBoard/xM Linux distributions in the Linux examples are removed
