One of Promwad’s core competences is the development of network devices such as WiFi routers, plug computers, IPTV set-top boxes (STB), customer premises equipment (CPE). Most of these developments are based on systems-on-chip (SoC) by Marvell. Below is an overview of the most important Marvell SoC families, as well as a summary table with specifications.
Kirkwood processor family
Marvell Kirkwood SoCs include the high-performance integrated controllers 88F6281, 88F6192,88F6180 and 88F6280.
The Kirkwood SoC includes the computing core Marvell Sheeva 88SV131, which is fully compatible with the ARMv5TE architecture, and a 256 KB L2 cache.
Kirkwood processors are built around the Feroceon architecture developed by Marvell, feature an enhanced performance and a range of capabilities which help reduce the number of external components and, consequently, the cost of the device.
Application of Kirkwood SoCs in electronics development
Kirkwood SoCs are well suited for a wide range of applications, such as routers, gateways, media servers, data storage systems, digital set-top boxes (STB), network devices, access points and network printers.
An improved production technology (55 nm, Kirkwood—65 nm) enabled Marvell developers to increase the number of interfaces and cut power consumption for ARMADA 300/310 processors.
Application of ARMADA 300/310 SoCs in electronics development
ARMADA 300 (88F6282) SoCs are well suited for a wide range of applications, such as routers, gateways, media servers, data storage systems, thin clients, STBs, network devices, access points and network printers.
The ARMADA 310 (88F6283) is a processor version with low power consumption, which is designed for computer peripherals, consumer electronics, extension cards and small-size devices, such as plug computers.
The Marvell ARMADA 370 processor is a highly integrated and high-performance SoC with the ARM V7 architecture. Integrated support for floating point operations, 256 KB L2 cache and a wide range of input-output interfaces enables the ARMADA 370 to achieve new productivity levels and new degrees of integration and efficiency, while retaining an easy system structure.
Application of ARMADA 370 in electronics development
ARMADA 370 processors are well-suited for various home and corporate applications, including Smart Hub in home digital TV, network attached storage (NAS) devices, media servers, wireless access points and network devices.
ARMADA XP processor family
Multi-core ARMADA XP (Extreme Performance) processors are the first series of four-core ARM processors designed for use in enterprise-class cloud computing systems.
The Marvell ARMADA XP is based on an architecture with low power consumption and includes up to four ARM v7 MP cores (1.6 GHz). These features help achieve the best performance per watt needed for next-generation energy-efficient systems.
The ARMADA XP family supports the SMP and AMP modes with hardware cache coherency and a 64-bit DDR2/DDR3 memory interface at 800 MHz (effective data exchange frequency is 1600 MHz). These SoCs include up to 2 MBL2 cache, four x4 PCI-Express interfaces, multiple USB ports, as well as Gigabit Ethernet, SATA, an encryption module and advanced power management technologies.
Application of ARMADA XP SoCs in electronics development
Because the family includes five package-compatible processors with different numbers of cores and interfaces, ARMADA XP is ideal for various applications such as high-performance network devices wireless devices, web servers, NAS, home servers, laser printers, etc.
Link Street Gateway processor family
The Link Street Gateway (88E7251, 88E7221), a family of highly integrated SoCs, is designed to build low-cost switches and gateways.
Link Street SoCs support such standards as IEEE 802.1 and IEEE 1722 Audio / Video Bridging (AVB), which help send latency-sensitive streams (digital video, audio and industrial control) via Ethernet with low latency and guaranteed QoS.
The Link Street processor family uses network bandwidth reservation for reliable and high-quality streaming media content. Each TDM port supports up to eight full-duplex channels.
