摘要： A method of verifying the passage of a data write across a bus is provided including sending the data write from an originator across the bus to a target, counting the number of data entries received at the target with a counter, and transmitting a return echo write from the target across the bus to a return address. The method further includes attaching the counter value to other data associated with the return echo write and polling the return address. The method allows determination of the completion of a data write by comparing the number of data entries included in the data write with the counter value polled from the return address. Alternatively, in a data streaming environment the progress of a data write may be determined by comparing the number of data entries included in the data write at a select point in time with the counter value polled from the return address. Typical data entries which are counted may include, but are not limited to, bytes, words, double words, or similar data quantities.
摘要翻译：提供了一种验证跨总线通过数据写入的方法，包括：通过总线将数据写入发送到目标，通过计数器计数在目标处接收到的数据条目的数量，并发送返回回波写入从目标公交车到返回地址。该方法还包括将计数器值附加到与返回回波写入相关联的其它数据并轮询返回地址。该方法允许通过将数据写入中包括的数据条目数与从返回地址轮询的计数值进行比较来确定数据写入的完成。或者，在数据流环境中，可以通过将选择时间点上的数据写入中包括的数据条目的数量与从返回地址轮询的计数器值进行比较来确定数据写入的进度。计数的典型数据条目可以包括但不限于字节，字，双字或类似的数据量。
