- 요약 :The PCI local bus master interface block has been designed in this paper. In case of real time video data processing, The data transfer rate is exponentially increased and the ISA bus which has a 16bit and 8MHz bus architecture cannot meet that transfer rate. This bottleneck condition makes the high speed microprocessor wait for the data from peripheral devices. Therefore, the system performance is determined not by a microprocessor speed but by a peripheral device's speed. The PCI local bus architecture is focused on communication among the high bandwidth LSI devices. The PCI bus DMA interface was designed by Verilog HDL and synthesized with the Synopsis. The functional operation of the synthesized logic was verified with a cell delay calculator and the Cwave, verilog simulator. The expected PCI data operation with DMA was observed. The designed PCI DMA master interface operates as a PCI master device fully. It can initiates bus operation by itself. The DMA controller controls the data transfer between a system memories and a local memories. Therefore, the CPU can process other operation during the memory writing or reading operations.
