ISO/IEC 14576:1999 ED1

Information technology - Synchronous split transfer type system bus (STbus) - Logical layer

Scope

This International Standard specifies the logical specifications of STbus which is a high-performance
and highly reliable system bus. STbus adopts a synchronous transfer method with a
high-speed clock and a split transfer method enabling to minimize bus holding time during one
bus operation and to use a bus efficiently.

This International Standard is applicable to a high-performance system bus or an I/O bus in a multiprocessor system. Typical STbus applications are a system bus and an I/O bus in a tightly coupled multiprocessor system, and a system bus in a loosely coupled multiprocessor system.
