Abstract

<div notation="docdba" type="abstract" xml:lang="en"><p>A semiconductor device includes first and second CPUs, first and second SPUs for controlling a snoop operation, a controller supporting ASIL D of a functional safety standard and a memory. The controller sets permission of the snoop operation to the first and second SPUs when a software lock-step is not performed. The controller sets prohibition of the snoop operation to the first and second SPUs when the software lock-step is performed. The first CPU executes a first software for the software lock-step, and writes an execution result in a first area for the memory. The second CPU executes a second software for the software lock-step, and writes an execution result in a second area of the memory. The execution result written in the first area is compared with the execution result written in the second area.</p></div>
