Optimised compiler claims peak EEMBC Automarks score on ARM core ARM and Green Hills Software have collaborated on an optimised compiler for the ARM Cortex®-R5 processor that, the two companies say, enables the Cortex-R5 processor to meet the needs of the most challenging automotive applications more cost-effectively than any other MCU solution currently available EEMBC Labs has certified the Green Hills compiler, version 2015.1 as having achieved a performance score of 1.01EEMBC Automarks/MHz on the Cortex-R5 automotive MCUs from Spansion. This represents a 30% increase on previous performance scores, say GHS and ARM. The Green Hills toolchain has received certificates by accredited independent agencies TÜV Nord and Exida at the highest levels of automotive and industrial functional safety, including ISO 26262 ASIL D and IEC 61508 SIL4. This combined level of certification and performance will enable the Cortex-R5 to deliver performance, safety and cost advantages to automotive systems developers as it eliminates the need for custom MCU architectures. ARM www.arm.com Runtime visualisation tool adds Segger embOS Percepio AB, the Swedish developer of RTOS visualisation tools, has added embOS-Trace. This tool offers a new level of insight into the runtime world for embedded software developers using Segger embOS and Segger J-Link debug probes. Percepio embOS-Trace is the latest member in Percepio’s Tracealyzer family and the embOS integration has been developed in collaboration with Segger. Founded in 2009 and based in Västerås, Sweden, Percepio is a developer of highly visual runtime diagnostics tools for embedded and Linux-based software. Percepio’s tool family Tracealyzer facilitates understanding, troubleshooting and optimisation of embedded system code. The new line of Tracealyzer tools, including embOS-Trace, use the performance of Segger J-Link debug probes to offer continuous trace streaming of runtime events, such as scheduling, interrupt handlers, kernel calls and application events. Tracealyzer uses software-defined trace, where events are stored in a RAM buffer. This is very flexible, easy-touse, and does not depend on hardware trace support. In embOS-Trace the trace length is no longer limited by the available RAM. Percepio www.percepio.com No Boundaries Our mission-critical resistors are truly out of this world. In fact, soon they will be out of our solar system, helping NASA’s Voyager spacecraft travel where no Earth craft has gone before. Thirty-fi ve years and 11 billion miles... Now that’s reliability.
