Patent number: 8595518Abstract: The semiconductor integrated circuit according to the present invention includes a mode switching circuit for switching an operation mode of a main core circuit among a plurality of internal circuits between a normal operation mode and a stand-by mode; and a stand-by canceling circuit for instructing the mode switching circuit to cancel a stand-by mode, and the mode switching circuit and the stand-by canceling circuit are configured to operate in asynchronism with the system clock with stand-by voltage in the stand-by mode. Thus, the semiconductor integrated circuit is capable of achieving operations with reduced power consumption with restrained leakage current by further reducing power source voltage during a stand-by mode, while maintaining advantages of shortening a time required to return from the stand-by mode, and of requiring no additional circuitry, such as non-volatile memory, for returning from the stand-by mode and thus requiring no extra cost.Type: GrantFiled: March 14, 2011Date of Patent: November 26, 2013Assignee: Sharp Kabushiki KaishaInventor: Yasuyuki Kii

Patent number: 8339397Abstract: Appropriate shadowing processing is performed even if coordinate conversion calculation values of polygons have errors. A calculation section 5 performs hidden surface removal processing on normal polygons based on visual-point coordinates and depth values from a visual-point coordinate conversion processing unit 1, and updates a pixel memory 6 and a Z-buffer memory 7. Further, based on a comparison result of obtained depth values of each polygon and Z values stored in the Z-buffer memory 7, shadowing is performed only on a coordinate region positioned in front of back-facing shadow polygons and behind front-facing shadow polygons when seen from a visual point, and the pixel memory 6 is updated. As a result, even if coordinate conversion calculation values in graphic data on polygons have errors, an edge portion of the shadow polygons which is not intended to be shadowed is not shadowed.Type: GrantFiled: March 9, 2004Date of Patent: December 25, 2012Assignee: Sharp Kabushiki KaishaInventor: Yasuyuki Kii
