Description
The 64-bit PCI master/target megafunction interfaces bus mastering devices, such as direct-memory access (DMA) controllers or video coprocessors, to the PCI bus. It processes all data requests from the bus mastering device and translates them into PCI bus requests.
This megafunction is designed for a 64-bit PCI bus system, which doubles the data bandwidth of a 32-bit PCI system. It supports zero-wait state burst transfers and a very long burst length. The megafunction supports up to a 266 Mbytes per second data transfer rate, and both 64-bit and 32-bit data transfers.
The 64-bit PCI master/target megafunction contains the functions of a bus master and a bus target. The device data and status can be accessed as a PCI master or target. All compliant configuration registers are included in the megafunction and all configuration accesses are processed automatically. This megafunction is available in Altera Hardware Description Language (AHDL), Verilog HDL, VHDL, and netlist format.
