Designing AHB/PCI bridge

The PCI Local Bus is a high performance, 32-bit or 64-bit bus with multiplexed address and data lines. It is intended for use as an interconnect mechanism between highly integrated peripheral controller components, peripheral add-in boards and processor/memory systems. The AHB of AMBA (Advanced Microcontroller Bus Architecture) is also designed for high-performance, high clock frequency system modules. In SoC design, the AHB acts as a high-performance system backbone bus. The function of AHB/PCI bridges is to map various control signals and address spaces from one bus into those of another. This paper presents the design of the AHB/PCI bridge.
