Patent ID: 7181562

Claim:
An apparatus defined to communicate electronically with each of a Serial Attached SCSI (SAS) protocol device and a Serial ATA (SATA) protocol device, comprising: a phy configured to connect the apparatus to each of the SAS protocol device and the SATA protocol device; wired endian logic configured to communicate through the phy, the wired endian logic configured to interface a wired endian format of the apparatus with each of a big endian format of the SAS protocol device and a little endian format of the SATA protocol device; and internal circuitry configured to operate in accordance with the wired endian format, wherein the wired endian logic includes receipt logic including, receiving circuitry defined to receive a sequence of bytes in a native format associated with a device from which the data sequence of bytes is to have been transmitted, discrimination circuitry defined to identify the sequence of bytes in native format as one of a control sequence of bytes and a data sequence of bytes, data sequence processing circuitry defined to perform receipt processing on the data sequence of bytes while in native format, the receipt processing including unscrambling of the data sequence of bytes and cyclic redundancy check data generation, and conversion circuitry defined to convert the sequence of bytes from the native format to the wired endian format.
