  • Central processing unit with integrated graphics functions
    Patent number: 5938756
    Abstract: The integer execution unit (IEU) of a central processing unit (CPU) is provided with a graphics status register (GSR) for storing a graphics data scaling factor and a graphics data alignment address offset. Additionally, the CPU is provided with a graphics execution unit (GRU) for executing a number of graphics operations in accordance to the graphics data scaling factor and alignment address offset, the graphics data having a number of graphics data formats. In one embodiment, the GRU is also used to execute a number of graphics data addition, subtraction, rounding, expansion, merge, alignment, multiplication, logical, compare, and pixel distance operations. The graphics data operations are categorized into a first and a second category, and the GRU concurrently executes one graphics operations from each category.
    Type: Grant
