    Abstract: A semiconductor device 1 includes an image input unit 11 and an image output unit 12. The image input unit 11 receives first image data from a camera 91 and outputs second image data to a memory unit 93 through a shared bus 130. The image output unit 12 receives the second image data stored in the memory unit 93 through the shared bus 130 and outputs third image data to a monitor 92. The third image data is generated by performing an affine-conversion on the first image data. Magnification processing in the affine-conversion is not performed in the image input unit 11. In this way, it is possible to provide an excellent semiconductor device suitable for image processing or the like.

    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.

    Abstract: The execution time of a self diagnosis program is reduced. A compiler apparatus includes: a specify unit that specifies, out of a plurality of resources included in a diagnosis target apparatus, a use resource group being a set of resources used by an instruction string included in an object program executed on the diagnosis target apparatus; a determine unit that determines, in accordance with the specified use resource group, a target resource group being a set of resources to be targets of a self diagnosis in the diagnosis target apparatus; and an output unit that outputs, for causing the self diagnosis on the determined target resource group to be executed in the diagnosis target apparatus, information based on the target resource group to the diagnosis target apparatus.
