Apparatus and methods for rapid cyclic redundancy check calculations in data processing devices. The apparatus comprise a memory, a direct memory access controller operatively coupled to the memory, and a cyclic redundancy check circuit operatively coupled to the direct memory access controller, with the direct memory access controller configured to transfer data from the memory to the cyclic redundancy check circuit, and with the cyclic redundancy check circuit configured to calculate at least one check value for the data. The methods comprise transferring a data stream from a memory to a cyclic redundancy check circuit using a direct memory access controller, and calculating a cyclic redundancy check value for the data stream by the cyclic redundancy check circuit.
