Data transfer bus system and method serving multiple parallel asynchronous units.

摘要

A system and method for transferring data between a single channel unit (102) and multiple asynchronous storage devices (104). One embodiment of the present invention uses read strobe signals to indicate when the storage devices are to send data over a data bus (202), and to initiate a validity count-down which indicates when the data on the data bus (202) is valid. When the count-down has completed, the data on the data bus (202) is sampled. Another embodiment further includes checking the data for array parity errors while the data is sent and received to and from the storage devices. <IMAGE>
