Architecture Overview
The QL6432 device in the QuickLogic® QuickPCI ESP (Embedded Standard Product) family provides a complete and customizable PCI interface solution combined with programmable logic. This device eliminates any need for the designer to worry about PCI bus compliance, yet allows for the maximum 32-bit PCI bus bandwidth (132 MBps).
