Abstract (en)
[origin: WO2009071791A2] The invention relates to a method and a circuit for verifying data transferred between a circuit (21) and a processing unit (11), in which: the data originating from the circuit travels through a first temporary storage element (23) having a size representing an integer multiple of the size of data liable to be presented subsequently on a bus (27) of the processing unit; an address provided by the processing unit (11) destined for the circuit is stored temporarily in a second element (22); and the content of the first element is compared with a current data item (CDATA) originating from the circuit, at least when said data item corresponds to an address of a data item already present in this first element.
