1. Introduction
1.1 System Overview
The PEP Modular Computers CompactPCI systems described in this chapter operate
with the PCI bus architecture to support additional I/O and memory-mapped devices as
required by various industrial applications. In the following you will find the most impor-
tant information on all system-relevant CompactPCI features. For more detailed infor-
mation concerning the CompactPCI standard, please consult the complete Peripheral
Component Interconnect (PCI) and CompactPCI Specifications. You can connect to the

1.1.1
Note on CompactPCI
CompactPCI is an extension of the PCI specification. It has been optimized for industrial
and/or embedded applications that require a more robust mechanical form factor as
compared to Desktop PCI. CompactPCI systems use industry standard mechanical
components and high performance connector technologies to provide systems that are
well suited for rugged applications. CompactPCI stands for systems that are electrically
compatible with the PCI Specification, allowing low-cost PCI components to be used.
CompactPCI is an open specification supported by the PICMG, which is a consortium of
companies involved in utilizing PCI for embedded applications.
