    • A data transfer apparatus and a data transfer system intended to transfer data continuously input or output to/from a main memory without any interruption and to transfer continuous data on a general-purpose bus such as a PCI bus, and a recording medium storing a program that commands a computer to execute all or some of functions of each component of the data transfer apparatus or the data transfer system. If it is supposed that a capacity of a write buffer memory 4 is CAPW, an input rate of continuously input data is T1, and a maximum assumed value of an interval of bus access permissions issued by a CPU 1 is TW, data omissions can be prevented by setting CAPW, T1 and TW at values that satisfy: CAPW≧TW×T1
    • 一种数据传送装置和数据传送系统,用于将数据连续地输入或输出到主存储器而不中断,并且在诸如PCI总线的通用总线上传送连续数据,以及存储程序的记录介质 其命令计算机执行数据传送装置或数据传送系统的每个部件的全部或部分功能。 如果假设写缓冲存储器4的容量为CAPW,则连续输入数据的输入速率为T1,CPU1发出的总线访问许可间隔的最大假设值为TW,则可以省略数据 通过将CAPW,T1和TW设置为满足:CAPW> = TWxT1的值来防止
