    • A continuous data server apparatus incorporating a plurality of buffer memory units for storing the continuous data read out by the data memory control units and to be given to the communication control unit, at least one buffer memory unit being provided dedicatedly for each combination of one data memory control unit group formed by at least one data memory control unit and one communication control unit group formed by at least one communication control unit. The apparatus may further incorporate a plurality of calculation units connected in series, where each calculation unit is connected between corresponding one data memory control unit group and at least one buffer memory unit, and carrying out a prescribed calculation processing. The continuous data can be arranged over a plurality of data memory control units in word units, such that the data memory control units read out the continuous data in block units, the buffer memory units store the continuous data in block units, and the communication control unit transfers the continuous data obtained by reading out data the buffer memory units sequentially in word units.
    • 一种连续数据服务器装置,其包括多个缓冲存储器单元,用于存储由数据存储器控制单元读出的连续数据,并被提供给通信控制单元,至少一个缓冲存储器单元专门为一个数据的每个组合提供 由至少一个数据存储器控制单元形成的存储器控​​制单元组和由至少一个通信控制单元形成的一个通信控制单元组。 该装置还可以包括串联连接的多个计算单元,其中每个计算单元连接在相应的一个数据存储器控制单元组和至少一个缓冲存储器单元之间,并执行规定的计算处理。 连续数据可以以单位单位布置在多个数据存储器控制单元上,使得数据存储器控制单元以块为单位读出连续数据,缓冲存储器单元以块为单位存储连续数据,并且通信控制 单元通过以字为单位顺序地读出缓冲存储器单元的数据而获得的连续数据。

    • There are two classes of scheduling policy: a first class in which a completion of data transfer requested by a data transfer request within a deadline for completing the requested data transfer, specified for the request, is a primary key factor in determining an order of processing, and a second class in which a reduction of amounts of mechanical actions of a storage device required in carrying out the data transfer requested by the request is a primary key factor in determining the order of processing. Data transfer requests with respect to the storage device are sequentially accepted. Each data transfer request is classified into the second class while the current time has not yet exceeded a time earlier by a certain time than the deadline. Each data transfer request is classified into the first class after the current time has already exceeded the time.
    • 有两类调度策略:在完成请求数据传输的期限内由数据传输请求完成数据传输的第一类是为请求指定的,是确定处理顺序的主要关键因素 以及第二类,其中在执行由请求请求的数据传送所需的存储设备的机械动作的量的减少是确定处理顺序的主要因素。 依次接受关于存储设备的数据传输请求。 每个数据传输请求被分类为第二类,而当前时间还没有比截止日期早一段时间超过一段时间。 在当前时间已经超过时间之后,每个数据传输请求被分类为第一类。
