Patent number: 8719542Abstract: A processor includes a CPU core which executes a user program, and a data transfer apparatus. The CPU core stores a transfer request from a user program in a specific area of a main memory, in which the transfer request specifies the virtual addresses of a transfer source and a transfer destination in a memory space allocated to the user program. The data transfer apparatus refers to the specific area of the main memory and acquires a transfer request asynchronously to processing performed by the CPU core. The data transfer apparatus then identifies physical addresses corresponding to virtual addresses specified in the transfer request. After that, the data transfer apparatus transcribes original data stored in a storage area indicated by the physical address of the transfer source, to a storage area in a cache memory related to the virtual address or physical address of the transfer destination.Type: GrantFiled: August 31, 2009Date of Patent: May 6, 2014Assignees: Sony Corporation, Sony Computer Entertainment Inc.Inventors: Yuji Kawamura, Takeshi Yamazaki

Patent number: 8577096Abstract: An encoding apparatus encodes an image by tile in a smallest possible size while suppresses segmentation of a specific region in the image into tiles. Vertical lines at left and right ends of n-th face region are defined as boundary candidate vertical lines Lh(n) and Lm(n), and horizontal lines at upper and lower ends of the n-th region, as boundary candidate horizontal lines Lu(n) and Ls(n). A divider determines a horizontal line of another region existing within the range of the horizontal lines Lu(n) and Ls(n) of the n-th region as a line to be deleted. Further, the divider determines a vertical line of another region existing within the range of the vertical lines Lh(n) and Lm(n) as a line to be deleted. This processing is performed to the final region, then image data is divided using horizontal and vertical lines except the lines determined as lines to be deleted.Type: GrantFiled: December 9, 2009Date of Patent: November 5, 2013Assignee: Canon Kabushiki KaishaInventors: Yuki Shiraishi, Takeshi Yamazaki

Patent number: 8260072Abstract: This invention provides a technique of easily encoding image data to generate encoded data having high image quality within a target code amount using a small memory capacity by image encoding processing of performing frequency transform and quantization of each pixel block. A frequency transform unit separates image data into low frequency band data and high frequency band data. A coefficient quantizing unit, coefficient encoder, and code amount controller operate to encode the high frequency band data within a predetermined amount. When the encoding processing of the high frequency band data has ended, the quantization parameter of the low frequency band data is set based on the generated code amount of the high frequency band data. A coefficient quantizing unit, coefficient encoder, code amount detector, and quantization parameter updating unit operate to encode the low frequency band data into codes within a low frequency band target code amount.Type: GrantFiled: July 31, 2009Date of Patent: September 4, 2012Assignee: Canon Kabushiki KaishaInventors: Hiroshi Kajiwara, Takeshi Yamazaki
