  • SEMICONDUCTOR DEVICE AND HARDWARE VIRTUALIZATION METHOD
    Publication number: 20230176883
    Abstract: According to one embodiment, a semiconductor device restricts an OS capable of using a functional block by an OS identifier written in an attribute register for restricting an accessible OS, and creates operation setting values of a first input unit, a second input unit, and a screen synthesis unit per OS to describe them in a setting value list stored in a shared memory, and each of the first input unit, second input unit, and screen synthesis unit has a mask circuit that refers to the OS identifier of the attribute register and in which write of the operation setting values into the setting register group of an own block is hampered, the operation setting values being described in the setting value list created by an OS other than the OS having a use authority for the own block.

  • Image processing apparatus and image processing method
    Patent number: 10497149
    Abstract: An image processing apparatus according to one embodiment determines target resolutions of a plurality of source images based on a first horizontal direction size and a first vertical direction size which are a horizontal direction size and a vertical direction size of a backlight control unit of a first display, and a second horizontal direction size and a second vertical direction size which are a horizontal direction size and a vertical direction size of a backlight control unit of a second display, and converts the resolution of each of a plurality of source images such that the resolution of each of a plurality of source images becomes the target resolution.
