Full Description
Scope
This standard defines an interfacing system used to interconnect data processing, data storage, and peripheral control devices in a tightly coupled hardware configuration. The system has the following objectives:
1) To allow communication between devices on the bus without disturbing the internal activities of other devices interfaced to the bus.
2) To specify the electrical and mechanical system characteristics required to design devices that will reliably and unambiguously communicate with other devices interfaced to the bus.
3) To specify protocols that precisely define the interaction between the bus and devices interfaced to it.
4) To provide terminology and definitions that describe system protocols.
5) To allow a broad range of design latitude so that the designer can optimize cost or performance, or both, without affecting the system compatibility.
6) To provide a system where performance is primarily device limited, rather than system interface limited.
Abstract
New IEEE Standard - Inactive-Reserved.
This IEEE 1014 standard specifies a high-performance backplane bus for use in microcomputer systems that employ single or multiple microprocessors is specified. It is based on the VMEbus specification, released by the VME Manufacturers' Group in August of 1982. The bus includes four subbuses: data transfer bus, priority interrupt bus, arbitration bus, and utility bus. The data transfer bus supports 8-, 16-, and 32-bit transfers over a non-multiplexed 32-bit data and address highway. The transfer protocols are asynchronous and fully handshaken. The priority interrupt bus provides real-time interrupt services to the system. The allocation of bus mastership is performed by the arbitration bus, which allows to implement round robin and prioritized arbitration algorithms. The utility bus provides the system with power-up and power-down synchronization. The mechanical specifications of boards, backplanes, subracks, and enclosures are based on IEC 297 specification, also know as the Euroboard form factor.
