This is a summary of the new features and other major changes in this release:

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
