    • A bus bridge is connected to a primary bus and a secondary bus, and relays data between a master and a target which are each connected to a different one of the primary and secondary buses. The bus bridge includes a primary bus interface, a secondary bus interface, a data FIFO, and a register block. The register block, which can be written by the master, includes two registers corresponding to the primary and secondary buses. Relay information showing the number of entries of data to be relayed from the target to the master is registered in a register corresponding to a bus to which the target is connected. In a read transaction, the primary bus interface or the secondary bus interface reads data from the target until data of the amount shown by the registered relay information is stored in the data FIFO.
    • 总线桥连接到主总线和辅助总线,并且中继主机和目标之间的数据,每个主站和目标站之间连接到主总线和次总线之间的不同的总线。 总线桥包括主总线接口,辅助总线接口,数据FIFO和寄存器块。 可由主器件写入的寄存器块包括与主母线和辅助母线相对应的两个寄存器。 显示要从目标到主机中继的数据的条目数的中继信息被登记在对应于目标连接到的总线的寄存器中。 在读取事务中,主总线接口或辅助总线接口从目标读取数据,直到被注册的中继信息所示量的数据被存储在数据FIFO中。

    • A data transfer apparatus for transferring data between a system bus and a local bus at a high speed is provided. A bus bridge 101 is connected between a system bus 132 and a local bus 137. Data transferred between a CPU 133, an I/O device 136 and a main memory 135 on the system bus 132 are retained in an associative memory 106 via an associative memory control unit 105. When an access to this data from an I/O device 138 on the local bus 137 is generated, the data are transferred from the associative memory 106 to the I/O device 138. Thus, when a data transfer request from the I/O device 138 to the main memory 135 is generated, no bus cycle is generated on the system bus 132 as long as this data are retained in the associative memory 106. Consequently, the data can be transferred at a high speed.
    • 提供了一种用于在系统总线和本地总线之间高速传输数据的数据传送装置。 总线桥101连接在系统总线132和本地总线137之间。在CPU 133,I / O设备136和系统总线132上的主存储器135之间传送的数据经由关联式存储器106保留在关联存储器106中 存储器控制单元105。 当生成来自本地总线137上的I / O设备138的该数据的访问时,数据从关联存储器106传送到I / O设备138。 因此,当产生从I / O设备138到主存储器135的数据传输请求时,只要该数据被保留在关联存储器106中,就不会在系统总线132上产生总线周期。 因此,可以高速地传送数据。
