High-rel software package for instrument cluster processor

Green Hills Software is to support Freescale’s multi-core MAC57D5xx instrument cluster processor.

Contributions include:

• ‘Integrity’ separation kernel for applications combining safety, reliability and security


• ‘Multi’ integrated development environment (including multi-core debugger and profiler)


• C and C++ compilers


• MISRA C/C++ code quality tools


• ‘DoubleCheck’ static analyser


• Tool chain for ARM Neon media processing engine and floating point units

“Freescale’s MAC57D5xx processor family targets graphics-rich mid-range instrument clusters that require digital and analogue human interfaces such as gauges, dials and screens,” said Green Hills. “Its flexible multicore architecture utilises ARM Cortex-A and Cortex-M cores and features the Vivante 2D graphics processor, head-up display warping engine and integrated stepper motor drive.”
