    • A data bus interface channel controller circuit for an N-bit data bus is described. A FIFO command queue is coupled to receive and buffer one or more commands formatted for M-bit transactions. A FIFO data queue is coupled to receive and buffer N-bit formatted data packets. A first translation circuit is coupled to the FIFO command queue and configured to translate the each commands into a selected one of a plurality of transaction formats. A transmission control circuit is coupled and configured to receive and transmit commands removed from the FIFO command queue. The transmission control circuit is configured to track a number of outstanding transmitted commands and, in response to receiving a command having a transaction format different from the previously received command, delay transmission of commands on the N-bit data bus until the number of outstanding transmitted commands equals zero.
    • 描述用于N位数据总线的数据总线接口通道控制器电路。 FIFO命令队列被耦合以接收和缓冲针对M位事务格式化的一个或多个命令。 FIFO数据队列被耦合以接收和缓冲N位格式的数据分组。 第一翻译电路耦合到FIFO命令队列并且被配置为将每个命令转换成多个事务格式中选择的一个。 传输控制电路被耦合并被配置为接收和发送从FIFO命令队列中移除的命令。 发送控制电路被配置为跟踪多个未完成的发送命令,并且响应于接收到具有与先前接收到的命令不同的事务格式的命令,延迟N位数据总线上的命令传输,直到未被发送的数量 命令等于零。
