PCI interface by FPGA of hardware and software heterogeneous system: the format of technical report

摘要

In order to make possible real-time operations, such as image processing with a lot of data, and speech processing, realization of the Hardware and Software heterogeneous system having high-speed hardware and flexible software is spent. Because this Hw/Sw heterogeneous system is constituted from object-orientation, HwObiect and SwObject are introduced. It is possible for HwObject to be loaded to FPGA prepared on HwModule recognized as a PCI memory device arranged, and to perform like SwObject. It is possible for hardware and sofiware to emphasize and operate by it. HwModule are the PCI device constituted by CPU, a memory, and FPGAx3, and it also considers carrying out pipeline processing tied to three FPGA. Control of an interface and an internal bus, control of FPGA, etc. are described with emphasis on the PCI interface which controls HwModule by this paper.
