1. Introduction
1.1 System Overview
The PEP Modular Computers product described in this chapter operates with the
VMEbus architecture. In addition, some products also support the CXC and/or
Enhanced CXC (eCXC) local mezzanine interface standards which represent a stream-
lined variant of the VMEbus standard itself. Thus a wide range of I/O functions for indus-
trial applications are supplied. Some of the major advantages of the VMEbus standard
are:
• internationally accepted VITA standards (VMEbus, CXC, eCXC);
• broad range of available VMEbus solutions
• scalable processor performance
In addition, in combination with (e)CXC technology the VMEbus equipment offers the
following advantages:
• lower costs and optimized reliability thanks to reduced design complexity;
• compact I/O sub-systems thanks to easier I/O wiring.
For detailled information concerning the VMEbus and (e)CXC standards, please consult
the VMEbus and CXC Specifications which are available via the
VMEbus International
Trade Association (VITA): http://www.vita.com
.
Many system-relevant features that are specific for VMEbus systems can be found in
the ANSI/VITA VME64 Standard and in the VITA/
PEP CXC MPI Specification which,
despite its name, applies also to VMEbus MPI carriers.
The VME64 Standard includes the following information:
• VMEbus Specification
• Signal Lines, Bus Modules, Typical Operation
• Electrical Specifications
• Mechanical Specifications
The CXC MPI Specification includes the following information:
• Mechanical dimensions
• Electrical specifications
• Interface description
• ID Byte assignment
With reference to the (e)CXC aspects of mixed VMEbus+CXC systems please refer
also to the
PEP CXC Reference Manual.
