Abstract
The computer system includes a data storage device on a first data bus, a requesting device on a second data bus that initiates a request to read data from a cache line in the data storage device, beginning at a location not aligned with a first boundary of the cache line and including all remaining data in the cache line up to a second boundary. The computer system also includes a bridge device that retrieves the entire cache line from the data storage device but provides only the requested data to the requesting device.
