July 17, 2012 -- Green Hills Software, Inc. today announced its collaboration with Renesas Electronics Corp. for the development of Renesas' new RH850 family of automotive microcontrollers (MCU). Green Hills Software's MULTI multicore debugger, optimizing compiler, TimeMachine suite and processor probes will target the advanced capabilities of the new RH850 core, including its high-speed floating-point unit (FPU), enhanced peripherals, and multicore debug and high-speed processor-trace interfaces.

Today's automotive MCU developers are increasingly looking to satisfy functional safety requirements from ASIL (Automotive Safety Integrity Level) A to ASIL D together with lower power-consumption requirements in a high-performance package. Renesas' RH850 family will include multiple application-tailored product series including advanced driver-assistance systems (ADAS), supported by Green Hills Software's optimizing tool chain and debugger, allowing companies to select the product that matches their specific requirements. The RH850 family will extend from single-core to multicore with dual-core lockstep allowing for flexible functional-safety capabilities.

The long-time collaboration between Renesas and Green Hills Software has produced industry-leading optimizing compilers that offer tailored optimization for the RH850 family of MCUs. The Green Hills Software tools employ thousands of processor-independent and processor-dependent optimizations, including advanced techniques such as an advance dual-issue pipeline scheduler, inter-procedural optimizations, link-time automatic addressing mode optimization and code factoring. The result is technology that generates the fastest and smallest code for the RH850 family.

The MULTI IDE for the RH850 family offers integrated development, debug and programming tools, including AUTOSAR operating system awareness, which gives the user visibility into objects and tasks and system state; single-core and multicore build and debugging for bare-board (no OS) applications; flash programming for on-chip flash; new multicore instruction set simulator (ISS) with support for the RH850's hyper-threading capabilities; performance profiler; project builder; code coverage; run-time error checking; MISRA C adherence wizard; DoubleCheck integrated static code analyzer; and Green Hills target-debug agents for Renesas' on-chip debugging and in-circuit emulators.
