The ultra-low voltage Intel Celeron VME bus is a computer bus that combines the electrical standard of Motorola’s Versa Bus with the mechanical form factor of the Eurocard standard established in Europe.

The ultra-low voltage Intel Celeron VME bus has a variety of functions.

First, it supports high reliability, mandating that all systems must support data integrity and error correction technology to ensure reliable transmission of data.

Second, the ultra-low voltage Intel Celeron VME bus also supports high-speed transmission, using microprocessor control, using synchronous timing, each cycle can transmit multiple bytes, with high-speed data transmission capabilities.

In addition, it supports flexible extension, allowing the function of the bus system to be extended by adding different types of slave cards, back-up memory, etc.

At the same time, the ultra-low voltage Intel Celeron VME bus also has priority interrupt bus function and universal bus function. The priority interrupt bus is the bus used to process the interrupt requests of each module, while the universal bus allows the connection between the various parts to be established for signal transmission.

The ultra-low voltage Intel Celeron VME bus has the following features:

High reliability: The VME standard mandates that all systems must support a number of data integrity and error correction technologies to ensure reliable data transmission.
High-speed transmission: The use of microprocessor control, the use of synchronous timing, each cycle can transmit multiple bytes, with high-speed data transmission capabilities.
Flexible expansion: The VME bus allows the function of the bus system to be expanded by adding different types of slave cards, backup memory, etc., and these modules have a certain degree of independence.
Multiple data widths: The address width of the VME bus is 16, 24, 32, 40 or 64 bits, and the width of the data line is 8, 16, 24, 32, 64 bits, and the system can dynamically select them.
Support asynchronous data transmission: The VME bus data transmission mode is asynchronous, so it is only subject to the signal exchange protocol, and does not depend on the system clock.
Multiple transmission rates are supported: The data transmission rate of the VME bus ranges from 0 to 500Mb/s.
Support for UnalignedData transmission: It can transmit igneddata correctly, even if the data is discontinuous.
Error correction capability and self-diagnostic capability: Users can define I/O ports.
With backplane: With 21 card slots and multiple backplanes, conductive cooling modules can be used in military applications.

In general, the ultra-low voltage Intel Celeron VME bus has many functions and characteristics such as high reliability, high-speed transmission, flexible expansion, etc., and is widely used in various computer systems.
