VMIPCI-5565-110000 | Abaco Systems Reflective Memory Interface

Description

The VME-5565 Reflective Memory node card provides a high-speed, low latency, deterministic interface that allows data to be shared between up to 256 independent systems (nodes) at rates up to 170 Mbyte/s. Each Reflective Memory board can be configured with either 64 Mbyte or 128 Mbyte of onboard SDRAM. The local SDRAM provides fast Read access times to stored data. Writes are stored in local SDRAM and broadcast over a high speed fiber-optic data path to other Reflective Memory nodes.The transfer of data between nodes is software transparent, so no I/O overhead is required. Transmit and Receive FIFOs buffer data during peak data rates to optimize processor and bus performance to maintain high data throughput. • Network transfer rate of 43 Mbyte/s (4 byte packets) to 170 Mbyte/s (64 byte packets) • Dynamic packet size, 4 to 64 bytes of data • Up to 256 nodes • Connection with multimode fiber up to 300m, single-mode fiber up to 10km • Data written to memory in one node is also written to memory in all nodes on the network • High speed, easy to use fiber-optic network (2.12 Gbaud serially) • VME transfer rate 40 Mbytes • 64 Mbyte or 128 Mbyte SDRAM Reflective Memory

Embedded controller is a good and basic access device in Ethernet control network. An embedded controller is a control system that performs specified independent control functions and has the ability to process data in a complex manner. It is an electronic device or device controlled by an embedded microelectronic technology chip (including a series of microelectronic devices such as microprocessor chip, timer, sequence generator or controller), which can complete various automatic processing tasks such as monitoring and control. Embedded controllers are mainly used to control, monitor, manage or assist other devices in real time. It consists of a microprocessor chip, software that is solidified inside the chip, and other components. Embedded controller software includes: embedded real-time operating system, application program, application programming interface API, real-time database and so on. Working principle Embedded microprocessors Embedded cpus present a colorful scene compared with general-purpose cpus, and there are more than 100 kinds of 32-bit embedded cpus in the world alone. Embedded CPU mostly works in the system designed by specific user groups, which has the characteristics of low power consumption, small size and high integration, which is conducive to the design of embedded controller tends to be miniaturized, intelligent and closely integrated with network applications.

Embedded operating system Now the more popular Embedded operating systems in the world are: Microware OS9, Sun Java OS, Microsoft Windows CE, Windows NT Embedded, free software RT-Linux and so on. China's Kais Group has also developed a general embedded operating system Hopen with independent intellectual property rights.

Network interface Network interface provides the necessary conditions for embedded controller to access network. The network interface takes 32-bit CPU as the center, the controller completes the control function of the network interface, the communication interface has RS 232C serial interface, communication protocol repeater interface, network interface and so on. The Ethernet control network can be constructed by using embedded controller and network interface. With the support of distributed network computing platform, distributed control network can also be built.

Technical essentials The operating system platform and network communication platform of embedded controller are popular open platforms in the world, which lays the foundation for the openness of Ethernet control network. The operating system platform of embedded controller, such as RT-Linux, has strong function, and the application software development is fast and convenient. The application software developed on the Linux operating system can run directly in the RT-Linux environment, that is, the development of embedded controller application software does not need special software development systems and tools. The powerful embedded CPU provides the embedded controller with high performance, high speed processing power and flexible expansion mode. Support TCP/IP protocol, easy to achieve network interconnection and network expansion. Various networks can be used as embedded controllers to access the backbone network. These backbone networks have high communication speed, good real-time performance, and support distributed network computing to achieve network collaboration. Embedded controller, network interface and distributed network computing platform can not only build open and powerful Ethernet control network, but also realize seamless integration of control network and information network.

SBCS, short for single-board computers, are off-the-shelf commercial computers that excel at embedded iot and edge computing tasks due to their small form factor, high flexibility, ultra-durability, and superior performance. Windows single board computer refers to a single board computer that supports Microsoft's Windows Internet of Things operating system. SBC offers ready-to-use hardware preconfigured with processors, memory, I/O ports, chipsets, power inputs, and more components that are welded directly to the computer PCB (plastic circuit board), combining them onto a single board. SBCS are well suited for industrial applications because of their compact form and fanless design, which allows them to accommodate space-constrained deployments. The benefits of SBC Embedded iot applications present several challenges that are difficult for standard commercial computers to perform in edge deployments. In contrast, SBC configurations are capable of executing embedded iot applications. SBC is known for its small footprint and powerful performance, making it ideal for iot deployments. Due to their scalability, reliability, durability, service life, etc., they are used in a variety of applications such as industrial automation, automotive computers, healthcare, deep sea exploration, outer space, and military applications. SBC dimensions The SBC's form factor is much smaller than the ATX motherboard standard commonly found in PCS. In addition, there are a variety of SBC form factors that meet different form factor standards, including the ITX standard, the embedded Computer standard, and other smaller form factors. That said, choosing the type of form factor you need will largely depend on the needs of your application. So here are some form factors that are primarily used for embedded iot and edge computing applications.
