Green Hills’ Compiler 2015; performance & safety for IoT

May 08, 2015 // By Graham Prophet
Green Hills Software’s C and C++ compilers for 32-bit and 64-bit embedded processor architectures, including ARM and Power Architecture, now have added optimisations in Compiler 2015, that improve performance by 30%, as demonstrated in recent published EEMBC Automotive benchmarks.

EEMBC Technology Labs have 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.

The Green Hills Compiler 2015 enables software developers to increase their application’s run-time performance and decrease memory size, thus saving costly hardware changes. Processor manufacturers choose Green Hills compilers more than all other competing compilers when publishing their highest processor performance scores on EEMBC – the most widely accepted industry benchmarks. Also renowned for its quality and robustness, Green Hills compilers have earned certifications for the highest levels of industry-specific safety and security requirements, including ISO 26262 ASIL D (Automotive), IEC 61508 SIL 4 (Industrial) and EN 50128:2011 (Railway).

“In the automotive market, processor performance and code quality are critical challenges for developers,” said Markus Levy, EEMBC president. “The performance leap in these benchmark scores achieved by ARM and Green Hills is impressive. The beauty of these benchmarks is that they collectively resemble real-world code, so better benchmark results will typically yield higher-performing applications.”

Capabilities of Compiler 2015 include:

Targeted optimisations yielding as much as 30% performance improvement compared to earlier scores as demonstrated on recently published EEMBC Automark scores.

Improved safety and reliability features expanded traceability and the detection of more dangerous code conditions, even across modules and multiple libraries.

Increased developer productivity & flexibility is enabled by an expanded assembly language translation feature, advanced 64-bit linker optimisations and with increased control/visibility of job status reports.

Support for the new processors ARM Cortex-R5F and Cortex-M7 processors, joining the already comprehensive support for popular processors manufactured by more than 35 silicon partners based on ARM, Power Architecture, Intel Architecture, ColdFire, v850/RH850, MIPS, TriCore and others.
