Abstract
A semiconductor device performs a software lock-step. The semiconductor device includes a first circuit group including a first Intellectual Property (IP) to be operated in a first address space, a first bus, and a first memory, a second circuit group including a second IP to be operated in a second address space, a second bus, and a second memory, a third bus connectable to a third memory, and a transfer control circuit coupled to the first to third buses. when the software lock-step is performed, the second circuit group converts an access address from the second IP to the second memory such that an address assigned to the second memory in the second address space is a same as an address assigned to the first memory in the first address space.
