CAN/CSA-ISO/IEC 15776:04 (R2022)
VME64bus - Specification (Adopted ISO/IEC 15776:2001, first edition, 2001-12)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope and object
The VMEbus specification defines an interfacing system used to interconnect microprocessors, data storage, and peripheral control devices in a closely coupled hardware configuration.
The system has been conceived with the following objectives:
a) to allow communication between devices on the VMEbus without disturbing the internal activities of other devices interfaced to the VMEbus;
b) to specify the electrical and mechanical system characteristics required to design devices that will reliably and unambiguously communicate with other devices interfaced to the VMEbus;
c) to specify protocols that precisely define the interaction between the VMEbus and devices interfaced to it;
d) to provide terminology and definitions that describe the system protocol;
e) to allow a broad range of design latitude so that the designer can optimize cost and/or performance without affecting system compatibility;
f) to provide a system where performance is primarily device limited, rather than system interface limited.
