IAR embedded workbench and the STM32F4 series performance

摘要

IAR System~® announced that its development tool suite for ARM~®, IAR Embedded Workbench~®, delivers the best CoreMark scores ever for an ARM Cortex™-M4 microcontroller. The new version of IAR Embedded Workbench for ARM includes major speed optimisations now proven on hardware. Targeting the CoreMark suite to the STMicro-electronics STM32F417-IGT6 processor, with an operating frequency of 168MHz, the benchmark reaches the highest score on Cortex-M-based products running from embedded Flash memory: 2.98 CoreMark/MHz and a total CoreMark score of 501. Running from RAM with zero wait states, the benchmark cruises to a CoreMark/MHz in excess of 3.
