Abstract
A system and method for converting VXI block transfer cycles to PCI burst cycles. The present invention may also be generalized to convert between any of various types of buses which use block transfer cycles and burst cycles. A bus bridge or interface unit is coupled between a VXI bus and a PCI bus. The bus bridge includes a VXI to PCI adapter for converting VXI block cycles to PCI burst cycles. The bus bridge includes a buffer which receives VXI block transfer cycles and stores the VXI cycles. The bus bridge also includes control circuitry which tags data in the received VXI block transfer cycles in order to identify and separate different VXI block transfers. Once all the cycles of a given data transfer have been tagged, they are transferred along the PCI bus as a PCI burst cycle.
