INTRODUCTION
This user’s guide describes the Cyclone evaluation platforms for Intel’s family of i960
®
embedded processors:
• Cyclone EP — a standalone general purpose evaluation and development tool.
• PCI-SDK Platform — Cyclone EP equipped with a PCI bus interface. Part of Intel’s PCI I/O
Software Development Toolkit (SDK).
Both platforms allow you to connect one of several i960 CPU and Squall* modules. Using the different
CPU modules, you can evaluate the various i960 processors in a system environment, or “benchmark”
the performance of the various processors.
The PCI-SDK Platform — otherwise identical to the Cyclone EP — is equipped with PLX
Technology’s PCI 9060 (a PCI to 80960 bus bridge chip). The single-chip PCI 9060 features mailbox
and doorbell registers that allow command and status information to pass between PCI bus devices and
local bus devices. It can also generate PCI configuration cycles, which enables the PCI 9060 to become
the PCI system host.
Unless otherwise noted, all references in this manual to “Cyclone EP” also apply to the PCI-SDK
Platform. References that are specific to PCI-SDK Platform are clearly indicated.
