NEC porta il multi-core sui cellulari

Il gigante nipponico svela quello che descrive come il primo processore al mondo per cellulari ad integrare tre CPU sullo stesso chip. Dedicato ai telefonini multimediali di prossima generazione

Tokyo (Giappone) - Facendo leva su di una tecnologia multiprocessore simile a quella già impiegata da Sun e IBM per i loro processori di fascia alta, NEC ha forgiato un processore che promette di moltiplicare la potenza di calcolo dei cellulari 3G senza drenare l'autonomia delle batterie.

Il produttore giapponese ha spiegato che il chip, chiamato MP211, aprirà la strada all'integrazione, sulla prossima generazione di videotelefonini e smartphone, di funzionalità multimediali evolute quali TV digitale, videotelefonate, e riproduzione simultanea di più flussi video e audio.

Il nuovo processore adotta 3 core ARM e un DSP che condividono la stessa unità di memoria, una caratteristica che, secondo NEC, semplifica il design dell'elettronica e riduce i costi di produzione.
Per sfruttare le capacità del suo nuovo chip multi-core, NEC ha sviluppato un software ottimizzato per ripartire il carico di lavoro sulle tre unità di calcolo e consentire alle applicazioni di beneficiare del multithreading. Per lo sviluppo di tale software l'azienda ha detto di essersi avvalsa di Linux e di altro software open source, tuttavia non è chiaro se Linux sia anche alla base del software mobile che gestirà l'MP211.

L'azienda conta di rilasciare i primi campioni del suo chip all'inizio del prossimo anno, facendo seguire la produzione in volumi a partire dalla metà del 2006. I primi paesi in cui verrà commercializzato l'MP211 saranno il Giappone e la Corea, seguiti a breve distanza dall'Europa.

NEC ha sviluppato la propria architettura multi-core per processori mobili in collaborazione con ARM, leader nella progettazione di chip embedded per il mercato degli smartphone e dei PDA.

    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 Energy Manager 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.

  • Il Mediatek MTK1389DE (e versioni EE,FE e così via) sono basate su un'architettura simile, includono nel package sia una CPU per l' OS, un DSP da usare per decodifica video, un controller per la meccanica del lettore DVD e così via...
    In questo caso NEC ha semplicemente prodotto un package simile a quello già costruito dalla Mediatek, nulla di nuovo nè un multi-core.

  • Assolutamente no, in questo caso si tratta di un processore integrante tre core ARM e, pertanto, basato su di una tecnologia multi-core. Che poi sia un package o meno poco importa, la notizia è un'altra.
    Ciao.
