Dev't tools offer combined support for automotive processors

Green Hills Software has extended the industry's first combined support for the latest Freescale Semiconductor automotive processor families, namely, the Qorivva MPC5xxx targeting engine and body applications and the MAC57Dxx family targeting digital instrument clusters.

The Green Hills development suite seamlessly spans both the Power Architecture and ARM Cortex architectures with the MULTI IDE and multi-core debugger, optimising compilers, TimeMachine trace suite, and processor probes, enabling carmakers and their Tier 1 software developers to lower the cost and complexity of creating software compliant up to ISO 26262 level ASIL D while providing the highest performance and smallest code size in the shortest time for powertrain, hybrid, body, and instrument cluster applications.

Green Hills Software's MULTI development environment is an integrated set of tools optimised for Freescale's broad range of new automotive processors, leveraging CPU-specific features for highest performance and safety.

The latest Qorivva MPC57xx product family targets functions hidden from the driver that demand extremely compact code with high performance and stringent safety characteristics. The family ranges from simple, low-cost, single-core controllers up to the latest triple- and quad-core variants all based on Power Architecture e200 cores.

In the vehicle cabin, Freescale's MAC57D5xx family focuses on graphics-rich mid-range instrument clusters utilising a multi-core architecture based on the ARM Cortex-M and Cortex-A processors coupled with the Vivante 2D GPU (OpenVG 1.1), HUD warping engine and integrated stepper motor with powerful I/O processor, where performance, code size, and functional safety are also a concern.

Green Hills continues its leadership in development tools by delivering products qualified to the highest possible ISO 26262 level—ASIL D. The complete Green Hills tools environment is expanded and enhanced for the Freescale automotive processors in the following ways:

Adding the new Freescale Qorivva MPC5748G and new versions of the MPC5744P, MPC5746M, and MPC5777M to the existing MPC57xx family support:

  • C/C++ and Embedded C++ compilers and complete tool chain support for the Power Architecture e200 cores including new saturated math instructions, the code size-reducing VLE instruction set, SPE signal processing unit, enhanced pipeline architecture, and other improvements producing up to 32 per cent increased performance on select EEMBC benchmarks.
  • The SuperTrace Probe adds high-speed Nexus Aurora serial trace (HSST) to its existing Parallel Nexus trace port option.

Adding the new Freescale MAC57D5xx processor and its three heterogeneous cores—ARM Cortex-A5, Cortex-M4, and Cortex-M0+—to the broad range of ARM Cortex cores already supported by Green Hills:

  • C/C++ and Embedded C++ compilers and complete tool chain that leverage the Neon media processing engine and floating point units.
  • Multicore run-control and real-time trace debugging with the Green HiIls Probe and SuperTrace Probe utilising industry-standard CoreSight from ARM Ltd.
