scope:
This standard describes a high performance backplane bus for use in microprocessor based sytems. This parallel bus supports single and block transfer cycles on a 32-bit non-multiplexed address and data highway. Transmission is governed by an asynchronous handshaken protocol. The standard supports inter-module interrupts for facilitating quick response to internal and external events. The mechanics of the boards and chassis are based on IEC Publication 297: Dimensions of Panels and Racks. The bus allocation provides for multiprocessor architectures.
