New Cortex processor delivers performance and configurability for embedded markets
CAMBRIDGE, UK - May 15, 2006 - ARM [(LSE: ARM); (Nasdaq: ARMHY)] today announced at the Spring Processor Forum, in San Jose, California, the new Cortex™-R4 processor for the next generation of mobile phones, hard-disk drives, printers and automotive designs, targeting more than one billion units in the embedded market. The Cortex-R4 processor delivers exceptional performance and efficiency to execute the complex control algorithms and real-time workloads in next-generation embedded products.
The Cortex-R4 processor enables configurability during synthesis to optimize the processor for different embedded applications through the memory protection unit, caches and tightly coupled memory (TCM). It does this without compromising the underlying ARM® instruction set compatibility, maximizing the reuse of existing software investments by application developers and third parties.
“For many years the low power, low cost ARM processor has been the architecture of choice for embedded microprocessor applications,” said Will Strauss, president and principal analyst, Forward Concepts. “With the Cortex-R4 processor, ARM has listened to its customers and produced the product needed for the next generation of design challenges, continuing the ARM tradition of finding the market sweet spot and providing appropriate solutions to serve that market.”
The enhanced configurability of the Cortex-R4 processor provides specific benefits for key markets including:
“The embedded market is evolving rapidly as systems become more sophisticated and software workloads increase in computational size and complexity.” said John Cornish, VP, Marketing, Processor Division, ARM. “The new Cortex-R4 processor meets the needs of next-generation embedded products by delivering exceptional performance, efficiency, and configurability. This latest member of our Cortex processor family gives chip designers unparalleled capabilities for the development of 3G phones, hard-disk drives, imaging and automotive systems”.
The Cortex-R4 processor provides the increased performance essential to address the diverse needs of the embedded market. The processor features an advanced microarchitecture with dual instruction issue capability to deliver more than 600 Dhrystone MIPS in a performance optimized 90nm implementation, based upon the ARM Artisan® Advantage™ library. The processor also provides key savings in cost and power consumption for system developers, occupying less than 1mm2 and consuming less than 0.27mW/MHz in an area optimized 90nm implementation.
ARM has already secured three lead licensees for the Cortex-R4 including Broadcom, and the processor has received support from major EDA, RTOS and tools vendors.
"Broadcom’s design teams have been working with ARM to accelerate our leadership position in a number of markets, including next-generation storage, networking, and mobile devices,” said Ed Frank, VP of Research & Development, Broadcom. “The new Cortex-R4 processor from ARM will bring significant performance and functionality benefits to our products and enhance the end user’s experience.
Cortex-R4 Processor-based System Benefits
The Cortex-R4 processor runs the ARMv7 ISA making it fully backwards compatible with existing ARM code that powers billions of systems around the world, and is optimized for the Thumb-2 instruction set. This allows numerous benefits including lower clock speed, bringing power-saving advantages; higher performance, which offers feature-rich additions to mobile phones and automotive designs; and more complex algorithms for higher performance digital imaging and hard-disk drive systems.
Using the Thumb-2 instruction set, together with the ARM RealView Development Suite, allows on-chip memory sizes to be reduced by up to 30 percent, saving significant cost in the system. In addition it can produce a 40 percent performance improvement over the previous Thumb instruction set running on an ARM946E-S™ processor. As memory is an increasingly large proportion of a chip, this provides a significant saving in area and cost to chip makers using the processor for SoC devices.
The ARM Cortex-R4 processor is available for licensing now, along with the majority of the supporting technology. The Instruction Set Simulator (ISS) and RealView Development Suite tools environment for the Cortex-R4 processor is available today to lead and existing licensees, and for general release on request.
The complementary technologies for implementing full SoC solutions such as the AMBA 3 AXI Interconnect (PL301), Configurable Dynamic Memory Controller (PL340), Static Memory Controller Family (PL350) and L2 Cache (L220) are all available now.
