NEWS: EEMBC scores Freescale i.MX31 with 2X boost using ARM Compiler

El Dorado Hills, Ca. – New certified benchmarks from Embedded Microprocessor Benchmark Consortium (EEMBC) indicate a two-fold improvement in performance on the ARM processor-based Freescale i.MX31 multimedia applications processor, when tested with the ARM RealView RVCT 3.1 build 559 compiler.

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 new results supersede a previous set of certified scores using a GCC version 3.43 compiler and limited – O2 optimizations. Original scores were certified running under the Linux OS; the new scores were certified running without an OS.

“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.
