Freescale automotive processor get ISO 26262 ASIL D qualified code tools

May 30, 2014 // By Graham Prophet
Green Hills Software has announced combined support for the latest Freescale Semiconductor automotive processor families – the Qorivva MPC5xxx targeting engine and body applications: and the MAC57Dxx family targeting digital instrument clusters. The offering, says GHS, combines high performance with functional safety for new ARM Cortex and Power Architecture families.

The Green Hills development suite spans both the Power Architecture and ARM Cortex architectures with the MULTI IDE and multicore 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, exploiting CPU-specific features for highest performance and safety. The Qorivva MPC57xx product family targets functions hidden from the driver – engine control, vehicle dynamics and networking – 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 new MAC57D5xx family focuses on graphics-rich mid-range instrument clusters utilising a multicore 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.

Adding the Freescale Qorivva MPC5748G and 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% 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 Freescale MAC57D5xx processor and its three heterogeneous cores – ARM Cortex-A5, Cortex-M4 and Cortex-M0+ – to the broad range
