Abstract:
An input/output expansion bus with a 32- or 64-bit width is described in this standard. The SBus is designed for systems requiring a small number of expansion ports. SBus Cards may be connected to a standard SBus Connector mounted on the motherboard. SBus Devices may also be attached to the SBus directly on the system's motherboard. The dimensions of the Sbus Card are 83.8 mm by 146.7 mm, making the cards appropriate for small computer systems that make extensive use of highly integrated circuits. The SBus cards are designed to be installed in a plane parallel to the system's motherboard as mezzanine cards. They are designed to provide connections for device...
Scope:
SBus is a high performance computer I/O interface for connecting integrated circuits and SBus Cards to a computer system motherboard. This standard defines the mechanical, electrical, environmental, and protocol requirements for the design of SBus Cards and the computer system motherboard that supports those cards. Every SBus Card shall implement appropriate self-descriptive and initialization firmware using FCode, which is similar to the Forth programming language. The details of this firmware standard are beyond the scope of IEEE Std 1496-1993. The currently active IEEE working group, P1275, will define this firmware interface standard (see IEEE P1275). In...
Purpose:
SBus is intended to provide a high performance I/O bus interface with a small mechanical form factor. The small size, high levels of integration, and low power usage of SBus Cards enable them to be used in laptop computers, compact desktop computers, and other applications requiring similar characteristics. SBus Cards are mounted in a plane parallel to the motherboard of the computer system, allowing the computer system to have a low profile. SBus is not designed as a general purpose backplane bus. SBus allows transfers to be in units of 8, 16, 32, or 64 bits. Burst transfers are allowed to further improve performance. SBus allows a number of SBus Master dev...
