Microcontrollers triple industry benchmark results
Freescale Semiconductor's Qorivva mcus reached 'unprecedented' levels of performance in a recent industry standard automotive benchmark test. The Qorivva 32bit MPC5674F achieved a benchmark score of 305 Automarks in the Embedded Microprocessor Benchmark Consortium's AutoBench suite of tests. According to Freescale, this demonstrates over three times the performance of the previous highest score set by a competitor.
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. It then adds 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 mcu 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."
