First Claim
Patent Images
1. A method of transferring data, the method comprising:
- calculating by a first device, a data check field of a data frame based on from a predetermined identification field and a plurality of data bits, wherein the predetermined identification field represents at least one of a content, source or target of the plurality of data bits; and
transmitting, by the first device to a second device, the data frame comprising the plurality of data bits and the data check field without directly transmitting the predetermined identification field.

19. An integrated circuit comprising:
-
a bus; a bus master circuit coupled to the bus; and a data storage circuit coupled to the bus, the data storage circuit comprising a data storage area, an address decoder, and a read checksum generator, the data storage circuit configured to receive a read address from the bus, decode, by the address decoder, the received read address to produce a decoded read address, access data from the data storage area based on the decoded read address, calculate by the read checksum generator, a read data check field from the accessed data and the decoded read address, and transmit the read data check field on the bus without directly transmitting the decoded read address. - View Dependent Claims (20, 21)
