Abstract: Means which enables image conversion in which a plurality of conversion results can be output without once saving all of video-image data, which has been input from image-pickup means, in a storage medium is provided. A single line memory having a plurality of lines is used while switching the role thereof for a reading use by a video-image converting means and a use for inputting image data from the image-pickup means. The image converting means obtains an input image, which is in the line memory, and carries out conversion of the input image based on a conversion specifying means interpreted by an instruction decoder.

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: 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.
