|Freescale Qorivva microcontrollers triple industry benchmark results|
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 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 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.”
Implications for the industry
Direct injection fuel systems need a high level of computing performance to precisely control when to inject fuel and the duration that the injector remains open, while simultaneously monitoring multiple external events such as oxygen levels, air temperature, road speed and exhaust gas composition in order to optimize the delivery of fuel for clean burning and optimal engine efficiency.
The Qorivva MPC5674F MCU is designed to run at higher central processing unit frequencies compared to early engine computers. This means it can execute individual tasks faster than other comparable devices. It is also engineered to run several processes in parallel, so it can execute dual instructions and compute complex signal processing algorithms simultaneously. This gives automotive developers a unique performance opportunity with which to optimize today’s combustion engines as well as hybrids and electric vehicles. This performance is delivered within the framework of Freescale’s zero-defect design and manufacturing process, which enables auto makers to offer extensive powertrain warranties.
The next generation of automotive MCUs
The Qorivva MPC5674F is currently sampling and is expected to be auto qualified in mid-2011.
