CONFIGURATION FOR EXCHANGING DATA USING CYCLIC REDUNDANCY CHECK (CRC) CODE, METHOD AND APPARATUS FOR AUTOMATICALLY GENERATING CRC CODE FROM DATA EXCHANGED ON DATA BUS

摘要

PPROBLEM TO BE SOLVED: To disclose a method and an apparatus for exchanging data encoded for a cyclic redundancy check (CRC-encoded) data. PSOLUTION: An embodiment of the configuration includes at least two blocks connected by an address bus and a data bus on which data are exchanged between the blocks. A snoop block is connected to the address bus and the data bus and configured to receive an address from the data bus. The snoop block includes an address masking circuit configured to generate at least one snoop address by masking an address which can be received from the data bus. A CRC block is connected to the data bus and the snoop block and configured to generate a CRC code from data when a data address transferred on the address bus is matched with at least one snoop address.
