ARM Extends Cortex Family with First Processor Optimized for FPGA

The ARM Cortex-M1 Processor Enables OEMs to Reduce Development Costs Through Standardization on a Single Architecture Across FPGA, ASIC and ASSP

CAMBRIDGE, England, March 19 // -- ARM [(LSE:ARM); (Nasdaq: ARMHY)] today announced the availability of the
ARM(R) Cortex(TM)-M1 processor - the first ARM processor designed specifically for implementation on FPGAs. The ARM Cortex-M1 processor extends the range of the ARM Cortex processor family and enables OEMs to standardize around a common architecture across the performance spectrum. Actel has worked with ARM as lead Partner and is the first licensee of the Cortex-M1 processor for use by their FPGA customers.

ARM and Actel will both be demonstrating the Cortex-M1 processor at the Embedded Systems Conference in San Jose, Calif., April 2-5.

The Cortex-M1 processor enables OEMs to achieve significant cost savings through rationalization of software and tools investments across multiple projects spanning FPGA, ASIC and ASSP, plus greater vendor independence through use of an industry-standard processor. The Cortex-M1 processor is supported by leading FPGA synthesis vendors, software development tools, and real-time operating systems, giving FPGA designers unprecedented choice and flexibility.

"Gartner Dataquest maintains that FPGAs/PLDs have a very bright future,"
said Bryan Lewis, research vice president, Gartner Dataquest. "We expect solid growth (15.7 percent) to resume in 2008 and forecast the FPGA/PLD market to outperform semiconductors from 2008 onward."(1)

"The Cortex-M1 processor extends the reach of the ARM architecture in the FPGA domain, and advances our goal of providing processor solutions for the entire digital world," said Graham Budd, EVP and general manager, Processor Division, ARM. "By leveraging ARM's vast installed user base in the ASIC/ASSP and microcontroller markets, along with support from our own RealView(R) family of tools as well as product support from the ARM Connected Community, the Cortex-M1 processor will deliver significant savings to OEMs in terms of software development resources, tools, and training."

Actel has licensed the Cortex-M1 processor and will make it available at no additional cost to their customers. The FPGA-optimized Cortex-M1 processor offers users of Actel's flash-based M1-enabled Actel Fusion Programmable System Chips and ProASIC3 FPGAs a compact and efficient processor satisfying the requirements of a wide range of end applications. Actel will support the
Cortex-M1 processor with its CoreConsole IP Deployment Platform, its SoftConsole program development environment and Actel Libero Integrated Design Environment - all available for free download from Actel's website.

"Following the success of our ARM7(TM) family-based solutions, Actel worked closely with ARM to optimize its Cortex-M1 processor for FPGA implementation from the ground up, making it an extremely valuable addition to our growing processor library," said Rich Brossart, vice president, product marketing, Actel. "Free of the contract negotiations and fees typically associated with industry-standard processor cores, Actel will make the Cortex-M1 processor available to those companies who desire highly programmable solutions regardless of application or volume."

Tools and Peripherals Support

The Cortex-M1 processor will be fully supported by forthcoming releases of the ARM RealView(R) Development Suite and RealView Microcontroller Development Kit. The RealView Development Suite will include a complete instruction set system model (ISSM) allowing developers to create and test applications for the Cortex-M1 processor out of the box. Developers can easily customize the RealView Development Suite's debugger to visualize and interact with peripherals added around a Cortex-M1 processor, and will also be able to connect and debug applications running on Cortex-M1 silicon using ARM's high-performance RealView ICE and ULINK(R)2 run control units.

System performance and design turn around time are boosted further with ARM AMBA(R) compliant PrimeCell(R) peripheral IP, including ARM's latest ultra-efficient microDMA (PL230).

ARM Connected Community Partners, including CodeSourcery, Express Logic, IAR Systems, Mentor Graphics Inc., Micrium and Synplicity will all support the Cortex-M1 processor. For improved flow integration, the Cortex-M1 processor deliverables will include an IP description conforming to the IP-XACT standard from The SPIRIT Consortium.

Low area, high frequency and ease of use

The ARM Cortex-M1 processor is a streamlined three-stage 32-bit RISC processor that implements a subset of the popular, high density Thumb(R)-2 instruction set. This enables both the processor and software footprint to meet the area budget of the smallest FPGA devices, while retaining compatibility with Thumb code for any ARM processor from the ARM7TDMI(R) processor upwards. The Cortex-M1 processor is capable of more than 170 MHz, whilst occupying less than 15 percent area of popular low-cost FPGA devices.
Despite being the smallest processor in the Cortex family, the Cortex-M1 processor can deliver 0.8 DMIPS/MHz. Typical applications for the Cortex-M1 processor on FPGAs include embedded control, communications, networking and aerospace.
