ARCHITECTURE OVERVIEW
The QL5232 device in the QuickLogic QuickPCI ESP (Embedded Standard Product) family provides a complete and customizable PCI interface solution combined with 122,000 system gates of 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 MB/s).
