Abstract
The functionality of a first processor is checked with a second processor. A data word with a specified number of data bits is supplied to the first processor from a second processor at specified time intervals. Each data bit is assigned a function. Having processed a function, the first processor inverts the associated data bit and, at the end of a time slice, passes the data word to the second processor, which checks the transferred data word.
