Masaaki Ono, Academic Service Office for Systems and Information Engineering University of Tsukuba. 1 1 1 Tennodai Tsukuba Ibaraki 305 8573 Japan, A PCI Peripheral Component Interconnect bus interface circuit was developed for a network interface of a. dedicated cluster network called Maestro The PCI bus interface circuit is implemented on FPGA Field Programmable. Gate Array and can handle PCI target transfer as well as PCI master transfer Although the PCI target transfer of the. PCI bus interface circuit is limited for single transfer the PCI master transfer supports burst transfer. The operating frequency of the PCI bus is 66 MHz the data widths are 64 bits and the maximum theoretical. throughput is 528 Mbytes sec The PCI bus interface circuit was designed and implemented without using commercial. IP Intellectual Property Currently the PCI bus interface circuit is implemented on FPGA of the Maestro2 and. Maestro3 network interface boards to connect the NI boards with the host personal computers. pci pci pci pci 66 mhz 64 2 pci 2 1 pci pci 1 64 32
