Certified Performance Analysis
for Embedded Systems Designers
EEMBC Update - February 2011
“Using CoreMark™ to Demonstrate
Performance-Related MCU Features and Compiler Tradeoffs” CoreMark™ is well on its way to becoming the defacto standard benchmark for microcontroller performance analysis. This is why EEMBC members, such as STMicroelectronics, are using CoreMark to demonstrate the features and benefits of their microcontroller products. In this webinar, we'll begin with an introduction to the CoreMark™ basics, and then launch into a demonstration that shows the capabilities of the Adaptive Real Time "ART" Accelerator of the STM32 F-2 series, as well as tradeoffs based on compiler selection. The ART Accelerator allows the microcontroller to execute code from flash with a performance equivalent to 0 wait-states at 120MHz. In the process, we'll go over the setup of the benchmarking environment including the build options and compiler flags. We'll wrap up the webinar with a short discussion on how CoreMark™ ties in to the overall methodology on benchmarking embedded processors. Date:

White paper on this topic. Membership in this working group is $2500 for the first year. If you are interested in joining, please contact Markus Levy, EEMBC president. BrowsingBench™, a benchmark to measure the user’s browser experience, is nearing final release. This benchmark utilizes a unique approach previously unavailable in any browser-related benchmark. Participation is open to all EEMBC Consumer subcommittee and Board of Directors members. For further information on joining, please contact Markus Levy, EEMBC president. Freescale Semiconductor released certified EEMBC AutoBench results for its Power Architecture based Qorivva microcontrollers (utilizing Green Hills: PPC Version 5.20 compiler). The Qorivva 32-bit MPC5674F achieved a benchmark score of 305 Automarks, and Freescale's MPC564xA and MPC5566 MCUs scored 150 and 121 Automarks, respectively. View the scores. More than 3000 users have downloaded the CoreMark™ benchmark, with more than 200 scores posted to the website. Since our previous newsletter, users have posted CoreMark™ scores for the following processor/compiler combinations:
