Optimised compiler claims peak EEMBC Automarks score on ARM core

February 17, 2015 // By Graham Prophet
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.

The Spansion Traveo family of Cortex-R5 based automotive MCUs builds upon the Cortex-R4 based FCR4 family, providing scalability, real-time processing and high-performance in applications where safety is paramount. “An Automark score of 192 for a cost-effective automotive grade MCU at this price point sets a new bar for affordable MCUs in body, driver information and powertrain applications,” said Takeshi Fuse, senior vice president, automotive MCUs, Spansion. ”Combined with the recent announcement from ARM of a comprehensive safety package for the Cortex-R5 processor for ISO 26262 and IEC 61058 applications, we expect a further boost to the growing momentum of Cortex-R5 and the Spansion Traveo family in automotive and industrial safety products.”

Building upon the wide adoption of the Cortex-R processor family in automotive and industrial applications, there have been a number of recent new products based on the Cortex-R5 processor. The Cortex-R5 provides advanced fault management features and a comprehensive safety package for a wide range of ISO and IEC standards.
