ARM Announces First Integrated Multiprocessor Core
CAMBRIDGE, UK - May 17, 2004 - ARM [LSE: ARM, Nasdaq: ARMHY], the industry's leading provider of 16/32-bit embedded RISC processor solutions, today announced
at the Embedded Processor Forum, San Jose, Calif., the availability of a new form of licensable processor, which has been
developed as part of its ongoing partnership with NEC Electronics. The MPCore™ synthesizable multiprocessor, based on the
ARMv6 architecture, can be configured to contain between one and four processors delivering up to 2600 Dhrystone MIPS of performance.
The MPCore multiprocessor implements Adaptive Shutdown™ technology and the ARM® Intelligent%20Energy%20Manager technology to reduce power consumption by up to 85 percent. NEC Electronics will use the configurable ARM processor in high-performance,
low-power products across the consumer electronics, automotive and mobile markets.
The new ARM multiprocessor solution delivers greater performance at lower frequencies than comparable single processor solutions,
bringing significant cost savings to system designers. Multiprocessing is ideal for demanding applications executing multiple
tasks at the same time such as consumer entertainment and convergence devices in the home and car. Examples include a set-top-box
recording several TV channels while sharing home movies across the Internet, and an in-car navigation system delivering simultaneous
back-seat video gaming..
The MPCore multiprocessor supports up to four-way cache coherent symmetric multiprocessing (SMP), up to four-way asymmetric
multiprocessing (AMP), or any combination of both. This flexibility provides increased throughput and system responsiveness,
with full portability of existing applications and scalable performance for multithreaded applications. The ability to support
multiple workloads addresses the needs of networking devices to process more packet streams and higher data throughput.
"Multi-processing can give system designers very high processing performance combined with low-power consumption. Through
our partnership with NEC Electronics we have developed the ground breaking MPCore multiprocessor which delivers the benefits
of scalable multi-processing in a configurable and easy to use implementation," said Mike Muller, CTO, ARM. "Our commitment
to producing innovative IP enables our Partners to produce the most advanced digital products, and enrich the end-user experience,
in the consumer electronics and networking markets. These are areas where we are seeing considerable growth in the deployment
of the ARM architecture."
"The announcement of the high-performance, low-power MPCore multiprocessor is a major milestone in our ongoing collaboration
with ARM," said Hirokazu Hashimoto, executive vice president of NEC Electronics. "The MPCore multiprocessor enables us to
deliver high-performance and low-power solutions for next-generation multimedia processing applications in the wireless mobile,
home, and automotive markets. It is innovative IP that enables us to provide scalable system solutions to customers through
efficient software reuse based on the advanced MPCore multiprocessor architecture, and create true system LSI solutions for
next-generation digital devices."
Software and OS Support
The MPCore multiprocessor supports both SMP and AMP software models, and supports a broad range of OS (operating system) and
application software.
"Combined with innovative power conservation, the new ARM multiprocessor core will enable device manufacturers to deliver
high-performance applications," said Glenn Seiler, director, Product Marketing, MontaVista Software. "Developers will appreciate
the strong synergy between this technology and MontaVista Consumer Electronics Edition's dynamic power management capabilities
and native Linux support for symmetric multiprocessing."
"The MPCore multiprocessor provides the technology the industry needs to create complex and high-performance devices," said
Robert Day, director of Marketing from Mentor Graphics Embedded Systems Division. "Development of a multiprocessor interface
within our Nucleus PLUS RTOS will be consistent with the technology in the MPCore multiprocessor and we look forward to releasing
the Nucleus® operating system for this platform."
"At the KTH Royal Institute of Technology of Sweden, we have published multiple papers on the energy and performance advantages
of multiprocessor designs in embedded systems using a similar adaptive shutdown technique as supported by the MPCore multiprocessor,"
said Mats Brorsson, professor in Computer Architecture at KTH. "In transferring our OpenMP compiler technology to ARM that
simplifies the development of SMP applications, we have been able to demonstrate the advantages of multiprocessor technology
we had previously predicted."
The MPCore multiprocessor supports the ARMv6 architecture, with SIMD media extensions for next-generation rich multimedia
and convergent devices and ARM Jazelle® Java acceleration. The MPCore multiprocessor implements between one and four processors
with cache coherency using a modified MESI protocol. It also features configurable level 1 caches, 64-bit AMBA™ AXI interfaces,
vector floating-point coprocessors and programmable interrupt distribution. The processor supports Adaptive Shutdown of unused
processors to give dynamic power consumption as low as 0.57mW/MHz from a generic 130nm process excluding cache. The ARM Intelligent
Energy Manager technology can further reduce consumption by dynamically predicting the required performance and lowering the
voltage and frequency. The MPCore multiprocessor enables system designers to view the core as a single "uniprocessor", simplifying
development and reducing time-to-market.
Availability
The MPCore multiprocessor is available for licensing from ARM now. First silicon is expected Q2 2005. An evaluation system
for the MPCore multiprocessor with Linux 2.6 OS and development tools is available today to enable early software development
for MPCore multiprocessor designs.
