    • A controller issues a command to an HDD interface to transfer AV data stored in HDDs to a memory. The HDD interface, in compliance with the command, transfers the AV data stored in the HDDs to a memory mapped on a bus. A memory controller reads the AV data out of the bus, and writes the AV data into the memory. The controller outputs the address of the AV data to be outputted to the memory controller. The memory controller reads out the AV data of the designated address, and outputs them to an AV data output interface. And the AV data output interface outputs the AV data. The controller issues a command to the HDD interface memory to record the AV data stored in the memory into the HDDs. The HDD interface, in compliance with the command, reads the data out of a memory mapped on the bus, and stores them in the HDDs. The memory controller reads the AV data out of the memory, and outputs them to the bus. At the same time, the controller designates to the memory controller the address in the memory into which the AV data inputted from the AV data input interface are to be written. The memory controller reads the AV data out of the AV data input interface, and writes them into the designated memory. By accomplishing this series of actions in synchronism with the frame period, AV data are stored in the HDDs, and also AV data stored in the HDDs are outputted.
    • 控制器向HDD接口发出命令以将存储在HDD中的AV数据传送到存储器。 HDD接口根据该命令将存储在HDD中的AV数据传送到映射在总线上的存储器。 存储器控制器从总线读出AV数据,并将AV数据写入存储器。 控制器将要输出的AV数据的地址输出到存储器控制器。 存储器控制器读出指定地址的AV数据,并将其输出到AV数据输出接口。 并且AV数据输出接口输出AV数据。 控制器向HDD接口存储器发出命令,将存储在存储器中的AV数据记录到HDD中。 根据该命令,HDD接口从映射在总线上的存储器读出数据,并将其存储在HDD中。 存储器控制器将AV数据从存储器中读出,并将其输出到总线。 同时,控制器向存储器控制器指定要从AV数据输入接口输入的AV数据被写入的存储器中的地址。 存储器控制器从AV数据输入接口读出AV数据,并将它们写入指定的存储器。 通过与帧周期同步地完成这一系列动作,AV数据被存储在HDD中,并且还输出存储在HDD中的AV数据。

    • The present invention relates to a data recorder which chronologically records continuous data such as image data without interruption at high speed, a medium which stores the procedure of recording or reproducing in the data recorder as a program, and a method of accessing the data recorder. In one embodiment, the data recorder is equipped with a group of recording units, and each group unit has a SCSI adaptor and a hard disk. The hard disk is connected to the SCSI bus and the SCSI adaptor is connected to a PCI bus. With this construction, data to be recorded in the data recorder is split into units of a prescribed size and assigned and recorded on the group of recording units so as to utilize a plurality of hard disks as a single logical recording space.
    • 本发明涉及一种数据记录器,其按时间顺序记录高速无中断的连续数据如图像数据,将数据记录器中记录或再现的过程作为程序存储的介质以及访问数据记录器的方法。 在一个实施例中,数据记录器配备有一组记录单元,并且每个组单元具有SCSI适配器和硬盘。 硬盘连接到SCSI总线,SCSI适配器连接到PCI总线。 利用这种结构,要记录在数据记录器中的数据被分割为规定尺寸的单位,并被分配并记录在记录单元组上,以便利用多个硬盘作为单个逻辑记录空间。
