Paper Abstract

After analyzing the system architecture and the routine design method of a SCSI controller, one novel design project for the SCSI controller is proposed on the basis of SOPC and soft processor IP core technology. The NIOS soft processor IP core is chosen as the center controller in the application system. Except for NIOS processor, most of the peripherals around the SCSI module, including DMA data channel and data cache control logic, are integrated into one FPGA chip. Comparing with the routine design method, the new project has better features in the expansibility, scalability, improvability and in-system programmability. As an instance, the SCSI to ATA interface system based on SOPC is introduced and given the satisfying I/O speed test results.
