ARM Announces Class-Leading BDTI DSP Scores For The ARM1136J-S Processor

BDTI Benchmark results confirm that the ARM1136J-S processor achieves 25 percent better performance than the competition

CAMBRIDGE, UK - May 16, 2005 - ARM [(LSE: ARM); (Nasdaq: ARMHY)] today announced the availability of the full BDTI Benchmark scores for the ARM1136J-S™ processor. When compared to the nearest competitive solution, the ARM1136J-S processor shows a 25 percent better performance even at a lower clock speed.

"The ARM1136J-S processor has class-leading signal-processing speed. A preliminary analysis of BDTI Benchmark results showed that at 350 MHz, the ARM1136J-S processor is approximately 25 percent faster than a 370 MHz MIPS 24Kc processor with the DSP ASE extensions," said John Cornish, director, Product Marketing, ARM.

The ARM1136J-S processor certified results and the competitor comparison have been produced by Berkeley Design Technology, Inc (BDTI), a trusted industry resource for independent competitor analysis. The BDTI Benchmarks are a de facto industry standard for benchmarking processor signal processing performance. The BDTI Benchmarks are a suite of 12 algorithm kernels which represent key signal processing operations found in today's voice, audio and video codecs, which are independently developed and verified by BDTI.

The ARM1136J-S processor achieved a BDTIsimMark2000 score of 1230 at 350MHz. The table below shows the benchmark results of the ARM1136J-S processor compared to the preliminary benchmarks results for the MIPS 24Kc processor with DSP ASE extensions, announced earlier this year.

Processor	Clock rate	Relative performance*
ARM9E™	220 MHz	1
ARM11™	350 MHz	3.1
MIPS32 24Kc with DSP ASE	370 MHz	2.5

* Preliminary analysis of the MIPS 24Kc processor with DSP ASE, and relative performance comparison shown here are based on average speed for four simple benchmarks. These results may not be representative of performance on more complex tasks. The results for all cores are based on worst-case clock speeds for the TSMC CL013G process. Results 2005 BDTI.

"BDTI's independent performance benchmarking results clearly show that the ARM11 processor family outperforms the competition," said Cornish. "The ARM11 processor family has a leading position in the mobile and home entertainment markets; it delivers the highest levels of performance and power efficiency at comparable die area." The ARM11 processor family delivers up to 550MHz of performance with die area as low as 2.2 mm2 and power as low as 0.24 mW/MHz using 130nm foundry processes. The ARM11 processor family has achieved some 30 licenses, with companies such as Freescale, LSI Logic, Broadcom and Texas Instruments and is supported by the ARM Connected Community of more than 300 third-party software, tools and systems companies. The ARM11 processor family targets a broad range of consumer markets and introduces new technologies to address the needs of emerging applications. These new technologies include SIMD for media processing, Thumb-2 core technology to enhance code efficiency, TrustZone technology for security, Intelligent Energy Manager (IEM) and multi-processing for systems that require very high and scalable levels of performance to over 2,600 Dhrystone 2.1 MIPS. The ARM11 family includes the ARM1136J(F-S) processor, the ARM1156T2(F-S) processor, the ARM1176JZ(F-S) processor and the ARM11 MPCore multiprocessor.
