What is a VME backplane?
What is a VME backplane?
The VME bus is a scalable backplane bus interface. A Master which Reads/Writes data to a Slave board, and a Slave interface which simply allows data to be accessed via a Read or Write from a Master. VME Controller. The VMEbus Controller ‘controls’ access to the bus.
How does VMEbus work?
Like the 68000, VME uses separate 32-bit data and address buses. In order to allow both bus widths, VME uses two different Eurocard connectors, P1 and P2. P1 contains three rows of 32 pins each, implementing the first 24 address bits, 16 data bits and all of the control signals.
What is a VME connector?
VMEbus is a multi-user bus system for control technology. The bus is a backplane bus for 19” rack housing. At present, VMEbus supports nearly all processors.
What is VME used for?
VME started development in the early 1980s, and was standardized in 1987 as a computer bus standard for use in embedded applications. It was very widely deployed in a range of industrial, research, semiconductor process control, transport, medical and defense applications worldwide.
What is VPX backplane?
VPX is a broadly defined technology utilizing the latest in a variety of switch fabric technologies in 3U and 6U format blades. The Open VPX framework defines clear interoperability points necessary for integration between Module to Module, Module to Backplane and Chassis.
What is VME card?
VME stands for VERSA-Module Euro card introduced in 1981 for industrial, commercial and military applications. • Electrical and mechanical specifications are defined by the standard. • VME bus is a master-slave computer architecture.
What is VPX connector?
VPX, also known as VITA 46, refers to a set of standards for connecting components of a computer (known as a computer bus), commonly used by defense contractors. VPX provides VMEbus-based systems with support for switched fabrics over a new high speed connector.
What are VME cards?
VMEbus (VersaModular Eurocard bus) is a bus (computer data path) system, designed by Motorola, Signetics, Mostek, and Thompson CSF, that is used in industrial, commercial, and military applications worldwide. VME64 cards can be used on older VME bus systems and older VMEbus cards can be used on VME64 systems.
What is the difference between VME and VPX?
While VME was based on a bus, with signals daisy-chained at each slot, VPX is based on switched fabrics. One way to think of the bus is like a tollbooth. When there’s just one manned tollbooth, all of the cars in line have to wait for the ones in front of them to finish their transaction before they can go.
What is VPX computing?
VPX, also known as VITA 46, refers to a set of standards for connecting components of a computer (known as a computer bus), commonly used by defense contractors. Some are ANSI standards such as ANSI/VITA 46.0–2019. VPX provides VMEbus-based systems with support for switched fabrics over a new high speed connector.
