Abstract
A PCI interface includes a PCI core that operates at the PCI bus frequency and glue logic which provides an interface to a higher frequency clock domain. The glue logic includes FIFO buffers for addresses and data coming from or going to the PCI bus, and synchronizers for control signals coming from or going to the PCI core. In one embodiment, a novel synchronizer includes three flip-flops at least two of which are JK flip-flops.
