Abstract
Techniques of this disclosure may include processing data using one or more processors to produce a first image, including storing intermediate first results of processing the data in at least one internal memory of the one or more processors according to a first memory access pattern, processing the data using the one or more processors to produce a second image, including storing intermediate second results of processing the data in the at least one internal memory of the one or more processors according to a second memory access pattern, wherein the second memory access pattern is different than the first memory access pattern, comparing the first image to the second image, and generating an interrupt if the comparison indicates that the first image is different than the second image.
