May 14, 2008  Marvell has released three new RISC-based system-on-chips (SoCs) designed to consume very low power at 1GHz-plus speeds. The dual-core MV78200 controller and single-core MV78100 and MV76100 controllers are based on Marvell's ARMv5TE-compliant Feroceon CPU core, and ship with Linux drivers, toolchains, and BSPs (board support packages).The latest members of Marvell's Discovery Innovation Series family of controllers, the MV7x controllers enable "green" system design for devices including routers, base stations, high-volume laser printers, storage devices, and single-board computers (SBCs), says Marvell. The single-core MV78100 is pin-compatible with the dual-core MV78200 version, says the company, and the MV76100 is a stripped down, more cost-effective version of the MV78100. The controllers offer an on-chip crossbar architecture that provides any-to-any connectivity for concurrent transactions among multiple logical units, says Marvell.

Marvell provides Discovery reference design platforms, including software drivers, toolchain, and board support packages, for Linux, VxWorks, and BSD, it said. Discovery controllers are commonly used in high-end "line cards" such as Extreme Engineering's AMC (advanced mezzanine card) version of its dual-G5 PowerPC board, the XPedite6240, which incorporates the Discovery III MV64460. Marvell's Feroceon micro-architecture is also used in the company's Orion processor, which is commonly found in network-attached storage (NAS) devices. The Orion architecture was supported in the most recent 2.6.25 Linux kernel release. Other SoC (system-on-chip) vendors that have licensed the ARM instruction set architecture and implemented their own micro-architectures include Intel, with the XScale and XScale v3 micro-architectures, and Freescale, with i.MX. Marvell has long been known for its NIC chips, including wireless chipsets, and for other embedded, network infrastructure, and storage processors. But then in 2006, it expanded its horizons by acquiring Intel's mobile XScale/Bulverde chip family, after which it quickly ramped up production. Marvell's XScale-based PXA series are a mainstay in Linux-based embedded devices. Stated Dr. Simon Milner, VP/GM at Marvell, "With the launch of these enterprise-focused SoCs, Marvell sets new standards for system performance and integration with very low power consumption for a gigahertz class processor core." Availability Marvell did not provide pricing or availability information on the new MV7x series of Discovery controllers. Related Stories:
