Certified Performance Analysis
for Embedded Systems Designers
EEMBC Update - March 2011
Targeted at mobile platforms, BrowsingBench is EEMBC's newest system
benchmark suite and is used to measure the browsing experience.
BrowsingBench employs unique techniques to yield a browser- and
system-agnostic benchmark suite. This presentation will explain these
techniques, as well as other techniques used to ensure compliance and
accurate performance measurements between differing platforms. It will also
provide the first public results of this effort. The Multicore Expo, co-located with the Embedded Systems Conference (ESC) will include several interesting sessions utilizing EEMBC benchmark suites. Discounted registration lasts until March 25. Here are some short descriptions of those sessions: "Migrating Serial Code to Utilize a Scalable Number of Local and Networked Processing Cores", will utilize EEMBC's Networking Suite to show that with proper technique, and careful attention to the functionality and synchronization requirements of the code to be optimized, near-linear, scalable performance gains can be realized as the number of threads available to that code is increased. "Analyzing Multi-threaded Applications - Identifying Bottlenecks on Multicore Systems", will use various multithreaded execution scenarios generated through EEMBC's MultiBench as stimulus to analyze and identify the bottlenecks associated with operating systems, application code, and hardware architecture scalability. "Challenges Faced in Optimizing JIT Compilers for Multicore Mobile Platforms", presented by Samsung India Software Operations utilizes the EEMBC benchmarks to provide quantitative information regarding the various optimization techiques. Chaired by Jeff Caldwell of SonicWALL, the DPIBench working group is
currently reviewing the capabilities of a variety of test equipment to
verify whether their equipment could handle the DPIBench workload
requirements.
Membership in this working group is $2,500 for the first year. If you are
interested in joining, please contact Markus Levy, EEMBC president. Almost 3800 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:
