The Qorivva MPC5674F is designed to help automakers offer more fuel-efficient automobiles and meet stricter government-mandated emissions standards by enabling precise control of engine events, such as combustion, without sacrificing performance. The Qorivva MPC5674F’s combination of exceptional performance, advanced signal processing capabilities and ultra-large flash memory array addresses the growing computational demands of green engine designs.

The MPC567xF 32-bit MCU triples automotive powertrain industry benchmark

  32-bit Qorivva MPC5674F beats the competition by 3X in industry standard automotive testing

AUSTIN, Texas - Feb. 8, 2011 - Freescale Semiconductor announced today that one of its Power Architecture® based a href="http://www.freescale.com/webapp/sps/site/overview.jsp?code=POWER_ARCH_5XXX&WT.srch=1&WT.mc_id=Qorivva&gclid=CKW-h7XH5aYCFaRd7Aod4Q0i1A">Qorivva microcontrollers (MCUs) reached unprecedented levels of performance in an industry-standard automotive benchmark test. The Qorivva 32-bit MPC5674F achieved a benchmark score of 305 Automarks™ in the Embedded Microprocessor Benchmark Consortium´s (EEMBC® AutoBench™ suite of tests, demonstrating more than three times the performance of the previous highest score set by a competitor. Additionally, Freescale´s MPC564xA and a href="http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC55xxEVB&fsrch=1&sr=1">MPC5566 MCUs scored 150 and 121 Automarks, respectively.

The benchmark assesses an MCU´s performance by first performing a set of typical automotive processes, such as controller area network, tooth-to-spark (locating the engine´s cog when the spark is ignited) and road speed calculation, and then adding complex signal processing algorithms used in engine control or vehicle safety applications. The benchmark is used to help automotive engineers assess relative performance between embedded MCUs for automotive applications.

“Confirming such outstanding performance by our Qorivva MCUs is great news,“ said Ray Cornyn, director of Freescale´s Automotive MCU business. “Developed from the original Power Architecture technology, we have been enhancing and focusing the Qorivva MCUs to provide exceptional real time embedded processing capabilities and the excellent results shown from these latest implementations illustrates why Power Architecture technology remains the automotive market standard.“

Software Enablement

Green Hills latest MULTI® Integrated Development Environment (IDE) software, which features a Performance Profiler tool to help focus software optimization efforts, was used to achieve these unprecedented results. The optimized Green Hills tools enable our customers to utilize the full capability of the Qorivva microcontrollers.
