  • Marvell Unveils 1.5 GHz Tri-Core Processor Capable of 1080p 3D Video for Smartphones

    Marvell has introduced the world’s first 1.5 GHz tri-core application processor, the Marvell ARMADA 628. It incorporates a full System-on-a-Chip design (SoC) with three Marvell-designed, ARM-compliant CPU cores operating as the world’s first commercially available heterogeneous, multi-core, applications processor.

    The tri-core design of new ARMADA integrates two symmetric multiprocessing cores and a third core optimized for ultra low-power. The third core is designed to support routine user tasks and acts as a system management processor to monitor and dynamically scale power and performance.

    According to Marvell, the tri-core architecture provides superior performance and lower power over dual-core designs “while maintaining industry compatibility and leadership – ensuring a richer, faster and smoother experience than any other ARM-based processor available today.”

    The architecture is analogous to a hybrid muscle car. The ARMADA 628 is intended to perform like a race car engine on demand, while still delivering the frugal gas-mileage of a hybrid automobile. In real world terms, this enables the ARMADA 628 to play more than 10 hours of full 1080p HD video or 140 hours of music on a single charge while still providing 3 GHz of raw computational horsepower.

    The new Marvell’s processor comprises a complete SoC design – a first for the industry. In addition to the tri-core CPU, there are six additional processing engines to support 3D graphics, 1080p video encode/decode, ultra high fidelity audio, advanced cryptography, and digital photo data processing – for a total of nine dedicated core functions.

    The company said that the ARMADA 628 is also designed to be the first mobile CPU to provide high-speed USB 3.0 connectivity, which offers 10x faster performance than USB 2.0.

    "Marvell’s groundbreaking tri-core architecture is a unique solution to a long-time problem-how to achieve enterprise performance without breaking the limited power budget of smartphones, tablets and other mobile consumer devices," said Linley Gwennap, principal analyst of The Linley Group.

    The ARMADA 628 is based on a Marvell-designed ARM v7 MP compatible CPU offering 1.5 GHz performance. It offers support to use LP-DDR2 or DDR3 memory up to 533 MHz, a highly flexible display controller capable of driving four simultaneous displays at up t o 2K x 2K resolution, and a highly robust security subsystem that includes a secure execution processor.

    An integrated 3D engine renders 200 million triangles per second for an immersive game play experience and a multi-format video engine supports dual stream 1080p video for a true 3D visual experience. In addition, the ARMADA 628 supports DirectX, Open GL ES 2.0, and Open VG 1.1 – ensuring complete compatibility with the most hotly anticipated mobile game titles.

    ARMADA 628 supports RIM OS, Android™, Linux, Windows Mobile, and full Adobe Flash.

  • picoChip Develops First Public Access Femtocell Solution

    picoChip today unveiled the PC333, the first chip specifically designed to extend the femtocell into the realm of public access infrastructure such as metro femto, rural femto and strand-mounted systems.

    According to the company, the PC333 System-on-Chip (SoC) device is the first femtocell chip to support 32 channels (scalable to 64) for simultaneous voice and HSPA+ data, the first to support MIMO, the first to support soft-handover and the first to conform to the Local Area Basestation (LABS) standard.

    picoChip says that the PC333 enables small basestations for urban hot-spots, city-centers or public access to be made and deployed at a cost far lower than traditional approaches, “radically changing the economics of network infrastructure.”

    The PC333 is the highest-specification femtocell available, and represents a significant step in bringing a complete 3GPP Release 8 Local Area 42Mbps HSPA+ basestation onto a single-chip.

    LABS is the 3GPP definition for systems with higher performance than home-basestations, allowing higher capacity, 120km/h mobility and +24dBm output power for greater than 2km range.

    The PC333 supports 32 channels, each with both voice and HSPA+ data and, with picoChip’s smartSignaling technology, in excess of 400 simultaneous smartphone users. Two of the devices can also be cascaded to support 64 active channels. The product runs on a 700MHz ARM chip with TrustZone and variety of specialized hardware features for security. As well as LABS conformance and release 8 HSPA+ (42Mbps downlink, 11 Mpbps uplink), the PC333 supports soft handover, receive diversity and MIMO.

    “Someday, all basestations will be made like this,” asserted Doug Pulley, CTO of picoChip. “With the PC333 we have extended the parameters of femtocell performance to levels that would traditionally have been considered as ‘picocell’ or even ‘microcell’. This high performance coupled with zero-touch provisioning means carriers can routinely deploy femtocells as part of their wide-area network rollouts. We are already seeing the emergence of femtocells into rural and metropolitan-area basestations,” he added.

    “As data traffic rises inexorably, it is evident that conventional macrocell architectures cannot cope both from a cost and capability point of view. Service providers are going to be deploying different, innovative basestation architectures to address this challenge effectively,” stated Simon Saunders, Chairman of The Femto Forum.

    The PC333 will be sampled in 4Q2010 to “lead customers.”

  • Broadcom Offers Open Source HD Voice

    Broadcom announced that it is offering its BroadVoice family of voice codecs royalty-free and without any licensing fees.

    “As a direct response to customer demand for advanced, high-quality voice solutions and development tools”, Broadcom is releasing its wideband and narrowband BroadVoice codecs in both floating-point and fixed-point C code as open source software under the GNU Lesser General Public License (LGPL), version 2.1, as published by the Free Software Foundation.

    According to the company, by eliminating the royalties and licensing fees (required by competitive solutions), Broadcom is driving a cost effective transition to HD VoIP applications by enhancing the quality of voice transmissions enabling a higher quality audio experience.

    The availability of BroadVoice source code, under an open source software license, provides the industry with maximum flexibility in how it can be deployed and has the potential of addressing a wide range of next generation voice-related applications.

    "We are seeing an increase in the number of requests for HD voice support from service providers who want to differentiate their telephony services from their competition. By offering high performance and highly efficient BroadVoice voice codecs royalty-free, we are enabling manufacturers and service providers to transition to HD VoIP as a means to significantly improve their customers’ audio experience,"said Dan Marotta, Senior Vice President & General Manager at Broadcom’s Broadband Communications Group.

    Broadcom developed the BroadVoice family of voice codecs with two variants including a 32 kb/s version called BroadVoice32 for wideband (HD) speech sampled at 16 kHz, and a 16 kb/s version called BroadVoice16 for narrowband telephone-bandwidth speech sampled at 8 kHz.

    The company claims BroadVoice advanced voice codecs reduce the latency, complexity and bandwidth usage on a wide range of wideband and narrowband voice applications including voice-over-cable, voice-over-DSL, Ethernet IP phones, Wi-Fi VoIP phones and software-based VoIP client solutions. Additionally, for VoIP applications, distortion and echo are also reduced.

    BroadVoice is available on Broadcom’s cable, DSL and VoIP system-on-a-chip (SoC) solutions.

    When standardized by SCTE and ANSI, the BroadVoice16 and BroadVoice32 codecs are called BV16 and BV32, respectively. BV16 is a standard codec in PacketCable 1.5, PacketCable 2.0, ANSI/SCTE 24-21 2006, and ITU-T Recommendation J.161 specifications. BV32 is a standard codec in PacketCable 2.0, ANSI/SCTE 24-23 2007, and ITU-T Recommendation J.361 specifications.

    BroadVoice16 and BroadVoice32 have very similar codec structures. Both variants share most of the algorithm modules so when implemented together, substantial code sharing and memory reduction can be achieved.

    Now Broadcom is providing both the floating-point and fixed-point C source code of BroadVoice16 and BroadVoice 32 under an open source license (LGPL version 2.1) and on a royalty-free basis.

  • HD Webcam Shoots Real-time 720p at 30fps


    Samsung is expanding its range of CMOS image sensors with a new high-definition 1/4-inch, 1.2 Megapixel (Mp) system-on-chip (SoC) webcam.

    The S5K4AW is intended for embedding in both notebook and desktop computers.

    Developed specifically for real-time HD video capture, the imager supports 720p HD video at 30 frames per second, and captures VGA video at up to 60 frames per second.

    Dr Yiwan Wong, vice president of marketing for Samsung Electronics’ System LSI Division, said that by incorporating a technique called binning in 2×2 pixel groups, the S5K4AW addresses the oft-encountered problem of using webcams in low light.

    He said the imager is 3x more sensitive than current sensors.

    The binning technique also mean the imager can display standard VGA format without the need for cropping.

    Wong said this eliminates the "annoying problem" of losing the top or the bottom of a scene while video conferencing or video file sharing on social media networks such as YouTube.

    Mass production of the S5K4AW is expected in the first half of 2009.
