Soon it was officially standardized by the <a href="/wiki/International_Electrotechnical_Commission" title="International Electrotechnical Commission">IEC</a> as the IEC 821 VMEbus and by ANSI and IEEE as ANSI/IEEE 1014-1987. </p><p>The original standard was a <a href="/wiki/16-bit" class="mw-redirect" title="16-bit">16-bit</a> bus, designed to fit within the existing Eurocard <a href="/wiki/DIN" class="mw-redirect" title="DIN">DIN</a> connectors. However, there have been several updates to the system to allow wider bus widths. The current <i>VME64</i> includes a full <a href="/wiki/64-bit" class="mw-redirect" title="64-bit">64-bit</a> bus in 6U-sized cards and <a href="/wiki/32-bit" class="mw-redirect" title="32-bit">32-bit</a> in 3U cards. The VME64 protocol has a typical performance of 40 <a href="/wiki/Megabyte" title="Megabyte">MB</a>/s.<sup id="cite_ref-vitavme_3-2" class="reference"><a href="#cite_note-vitavme-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Other associated standards have added hot-swapping (<a href="/wiki/Plug-and-play" class="mw-redirect" title="Plug-and-play">plug-and-play</a>) in <i>VME64x</i>, smaller 'IP' cards that plug into a single VMEbus card, and various interconnect standards for linking VME systems together. </p><p>In the late 1990s, synchronous protocols proved to be favourable. The research project was called VME320. The VITA Standards Organization called for a new standard for unmodified VME32/64 backplanes.<sup id="cite_ref-vitavme_3-3" class="reference"><a href="#cite_note-vitavme-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> The new 2eSST protocol was approved in ANSI/VITA 1.5 in 1999. </p><p>Over the years, many extensions have been added to the VME interface, providing 'sideband' channels of communication in parallel to VME itself. Some examples are IP Module, RACEway Interlink, SCSA, Gigabit Ethernet on VME64x Backplanes, PCI Express, RapidIO, StarFabric and InfiniBand. </p><p>VMEbus was also used to develop closely related standards, <a href="/wiki/VXIbus" class="mw-redirect" title="VXIbus">VXIbus</a> and <a href="/wiki/VPX" title="VPX">VPX</a>.

This was later renamed "VME", short for Versa Module European, by Lyman (Lym) Hevle, then a VP with the Motorola Microsystems Operation. (He was later the founder of the VME Marketing Group, itself subsequently renamed to VME International Trade Association, or VITA). </p><p>John Black of Motorola, Craig MacKenna of Mostek and Cecil Kaplinsky of Signetics developed the first draft of the VMEbus specification. In October 1981, at the System '81 trade show in Munich, West Germany, Motorola, Mostek, Signetics/Philips, and Thomson CSF announced their joint support of the VMEbus. They also placed Revision A of the specification in the public domain. </p><p>In 1985, Aitech developed, under contract for <a href="/wiki/US_Army" class="mw-redirect" title="US Army">US Army</a> <a href="/wiki/TACOM" title="TACOM">TACOM</a>, the first conduction-cooled 6U VMEbus board. Although electrically providing a compliant VMEbus protocol interface, mechanically, this board was not interchangeable for use in air-cooled lab VMEbus development chassis. </p><p>In late 1987, a technical committee was formed under VITA under the direction of IEEE to create the first military, conduction-cooled 6U<span class="nowrap"> </span>× 160<span class="nowrap"> </span>mm, fully electrically and mechanically compatible, VMEbus board co-chaired by Dale Young (DY4 Systems) and Doug Patterson (Plessey Microsystems, then Radstone Technology). ANSI/IEEE-1101.2-1992 was later ratified and released in 1992 and remains in place as the conduction-cooled, international standard for all 6U VMEbus products. </p><p>In 1989, John Peters of Performance Technologies Inc. developed the initial concept of VME64: multiplexing address and data lines (A64/D64) on the VMEbus. The concept was demonstrated the same year and placed in the VITA Technical Committee in 1990 as a performance enhancement to the VMEbus specification. </p><p>In 1993, new activities began on the base-VME architecture, involving the implementation of high-speed <a href="/wiki/Serial_bus" class="mw-redirect" title="Serial bus">serial</a> and <a href="/wiki/Parallel_bus" class="mw-redirect" title="Parallel bus">parallel</a> sub-buses for use as I/O interconnections and data mover subsystems. These architectures can be used as message switches, routers and small multiprocessor parallel architectures. </p><p>VITA's application for recognition as an accredited standards developer organization of ANSI was granted in June 1993. Numerous other documents ( including mezzanine, P2 and serial bus standards) have been placed with VITA as the Public Domain Administrator of these technologies. </p> <table class="wikitable"> <caption>Evolution of VME </caption> <tbody><tr> <th>Topology </th> <th>Year </th> <th>Bus cycle </th> <th>Maximum speed (MB/s) </th></tr> <tr> <td>VMEbus32 Parallel Bus Rev.

The result is that, while VME is very 68000-like, the 68000 is generic enough to make this not an issue in most cases. </p><p>Like the 68000, VME uses separate 32-bit data and address buses. The 68000 address bus is actually 24-bit and the data bus 16-bit (although it is 32/32 internally) but the designers were already looking towards a full 32-bit implementation. </p><p>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. P2 contains one more row, which includes the remaining 8 address bits and 16 data bits. </p><p>A block transfer protocol allows several bus transfers to occur with a single address cycle. In block transfer mode, the first transfer includes an address cycle and subsequent transfers require only data cycles. The slave is responsible for ensuring that these transfers use successive addresses. </p><p>Bus masters can release the bus in two ways. With Release When Done (RWD), the master releases the bus when it completes a transfer and must re-arbitrate for the bus before every subsequent transfer. With Release On Request (ROR), the master retains the bus by continuing to assert BBSY* between transfers. ROR allows the master to retain control over the bus until a Bus Clear (BCLR*) is asserted by another master that wishes to arbitrate for the bus. Thus a master that generates bursts of traffic can optimize <i>its</i> performance by arbitrating for the bus on only the first transfer of each burst. This decrease in transfer latency comes at the cost of somewhat higher transfer latency for other masters. </p><p>Address modifiers are used to divide the VME bus address space into several distinct sub-spaces. The address modifier is a 6 bit wide set of signals on the backplane. Address modifiers specify the number of significant address bits, the privilege mode (to allow processors to distinguish between bus accesses by user-level or system-level software), and whether or not the transfer is a block transfer. Below is an incomplete table of address modifiers: </p> <table class="wikitable"> <tbody><tr> <th>Hex Code </th> <th>Function </th> <th>Explanation </th></tr> <tr> <td>3f </td> <td>Standard Supervisory block transfer </td> <td>Block transfer A24, privileged </td></tr> <tr> <td>3e </td> <td>Standard Supervisory Program access </td> <td>A24 instruction access, privileged </td></tr> <tr> <td>3d </td> <td>Standard Supervisor Data Access </td> <td>A24 data access, privileged </td></tr> <tr> <td>3b </td> <td>Standard Non-privileged block transfer </td> <td>A24 block transfer for normal programs </td></tr> <tr> <td>3a </td> <td>Standard Non-privileged Program access </td> <td>A24 instruction access, non-privileged </td></tr> <tr> <td>39 </td> <td>Standard non-privileged Data Access </td> <td>A24 data access, non-privileged </td></tr> <tr> <td>2d </td> <td>Short supervisory Access </td> <td>A16 privileged access. </td></tr> <tr> <td>29 </td> <td>Short non-privileged Access </td> <td>A16 non-privileged access. </td></tr> <tr> <td>0f </td> <td>Extended supervisory Block transfer </td> <td>A32 privileged block transfer. </td></tr> <tr> <td>0e </td> <td>Extended supervisory Program access </td> <td>A32 privileged instruction access. </td></tr> <tr> <td>0d </td> <td>Extended supervisory Data Access. </td> <td>A32 privileged data access. </td></tr> <tr> <td>0b </td> <td>Extended Non-privileged Block transfer </td> <td>A32 non-privileged block transfer. </td></tr> <tr> <td>0a </td> <td>Extended Non-privileged Program access </td> <td>A32 non-privileged instruction access. </td></tr> <tr> <td>09 </td> <td>Extended non-privileged data access. </td> <td>A32 non-privileged data access. </td></tr> <tr> <td><b>Note</b> </td> <td> </td> <td><i>A<sub>n</sub> as in A16, A24, A32 refers to the width of the address</i> </td></tr></tbody></table> <p>On the VME bus, all transfers are <a href="/wiki/Direct_Memory_Access" class="mw-redirect" title="Direct Memory Access">DMA</a> and every card is a master or slave. In most bus standards, there is a considerable amount of complexity added in order to support various transfer types and master/slave selection. For instance, with the <a href="/wiki/ISA_bus" class="mw-redirect" title="ISA bus">ISA bus</a>, both of these features had to be added alongside the existing "channels" model, whereby all communications was handled by the host <a href="/wiki/Central_processing_unit" title="Central processing unit">CPU</a>.
