PCI to NOR Flash Interface

LatticeReferenceDesign-LogoThis reference design brings the capability and the performance of the popular PCI Local Bus to the NOR-based Flash. It provides an interface between the CPU with PCI initiator interface and a NOR-type Flash memory by translating the PCI commands into appropriate signals to control the read/write of the NOR Flash. The basic knowledge of PCI specification is necessary to understand the design.
