PCI32 Interface v3.0 Fact Table Notes 1. Resource utilization depends on configuration of the interface and user design. Unused resources are trimmed by the Xilinx technology mapper. The utilization figures reported in this table are representative of a maximum configuration. 2. Designs running at 66 MHz in devices other than Virtex-II, Virtex-II Pro, Virtex-4, Spartan-3, and Spartan-3E require one GCLKIOB and two GCLKs. Virtex-4 implementations require additional BUFG for 200 MHz reference cl

PCI32 Interface v3.0 Bandwidth The PCI Interface supports fully compliant zero wait-state burst operations for both sourcing and receiving data. This interface supports a sustained bandwidth of up to 264 MBytes/sec. The design can be configured to take advantage of the ability of the PCI Interface to do very long bursts. The flexible user application interface, combined with support for many different PCI features, gives users a solution that lends itself to use in many high-performance applicat
