EEMBC Publishes New Certified Scores for Freescale i.MX31 With ARM Compiler

New Results Show Up to 2X Performance Increase

(PresseBox) ( EL DORADO HILLS, Calif., )
The Embedded Microprocessor Benchmark Consortium (EEMBC) today announced the publication of new certified benchmark scores for the ARM processor-based Freescale i.MX31 multimedia applications processor. Tested with the ARM® RealView® RVCT 3.1 build 559 compiler, the new results supersede a previous set of certified scores using a GCC version 3.43 compiler and limited -O2 optimizations.

The 532-MHz Freescale i.MX31 was tested in an out-of-the-box environment against four EEMBC® benchmark suites - AutoBench 1.1, ConsumerBench 1.1, OABench 1.1, and TeleBench 1.1 - yielding extensive data on the processor's expected performance in automotive/industrial, digital imaging, office automation, and fixed telecom applications.

"The ARM compiler helped the i.MX31 achieve up to a 2x increase in performance with one benchmark, and a 43 percent increase in overall performance with all four benchmarks over an earlier version of the GCC compiler," said EEMBC President Markus Levy. "These new benchmark scores demonstrate the benefits of ensuring that developers take advantage of the latest in compiler optimizations and technologies."

Freescale's i.MX31 processor, with a vector floating point coprocessor and L2 cache, is designed for wireless devices, such as portable media players and portable navigation devices, running computationally intensive multimedia applications. Based on an ARM1136JF-STM processor, its target devices include feature rich smartphones, digital video recorders, digital cameras, mobile gaming consoles, mobile multimedia players, and many other mobile wireless applications.

The ARM compiler, part of the RealView Development Suite 3.1, is designed to enable developers to get the best performance out of their ARM processor-based devices. ARM develops its compiler technology in conjunction with its processor technology to offer superior performance at the lowest possible memory cost.

"ARM uses the EEMBC benchmarks extensively during the development of our industry-leading processors and compilers, and these industry-recognized results show that we continue to be ahead of the field in delivering maximum real-world performance and power efficiency for a wide range of mobile and consumer applications," said Eric Schorn, vice president of marketing, Processors Division, ARM.
