摘　　要：在长时间大数据量记录手段上,目前多采用模拟量记录方式的磁带记录仪,但这种磁带记录仪功能单一,操作不灵活。本文针对这些缺陷提出了一种三端口I/O拓扑结构的SCSI磁盘记录仪,并给出了这种SCSI磁盘记录仪的SOPC工作原理及相应的SCSI系统控制器IP的设计、应用。仿真与测试的结果说明了这种磁盘记录仪具有记录数据的速率高、智能化等特点,这种采用IP技术的SOPC设计方法为测试领域的设备研制提供了一种新的途径。Magnetic tape recording, which is a typical analog storage method, is currently applied in the longplaying mass data storage. As its operation is not flexible, a remedial way-a SCSI interfaced disk-recording device with three I/O ports was introduced in this paper. The SOPC scheme and the design of SCSI system controller IP core for this device were also described here. The test and simulation results show that this Hard Drive Recording Device with SCSI interface has higher transfer rate and more intelligent, which overcame the defects of Magnetic tape recording device, and the SOPC design method with IPs is an effectual way to develop future test and measurement device.
