PCI to AMBA AHB Host Bridge
This PCI to AMBA AHB Host Bridge IP core enables data transfers between an AMBA® AHB host processor bus system and PCI bus based devices.
The bridge enables higher utilization of the bus’ available bandwidth by prefetching PCI data and buffering AHB data, and allows the host to initiate PCI accesses or to respond to transactions initiated by other PCI devices.
The PCI to AMBA AHB Host Bridge complies with the PCI bus specification versions 3.0 and 2.3, and can act as a PCI master and target. Furthermore it implements PCI bus arbitration, supporting up to seven PCI bus agents, PCI reset signal generation, and all types of PCI transactions provisioned by the standard.
The host connects to the bridge via master and slave 32-bit AMBA/AHB bus interfaces. The AHB slave interface allows the host to access the status and control registers and to initiate PCI Transfers, while data from the PCI target is communicated to the host via the AHB master interface.
The PCI to AMBA AHB Host Bridge has been designed for straightforward reuse, with proven design practices that ensure easy integration and smooth technology mapping. The PCI to AMBA AHB Host Bridge is available in synthesizable RTL or as a targeted FPGA netlist, and is delivered with everything required for rapid and successful integration and implementation.
