Patent number: 11190718Abstract: An apparatus is described that include a line buffer unit composed of a plurality of a line buffer interface units. Each line buffer interface unit is to handle one or more requests by a respective producer to store a respective line group in a memory and handle one or more requests by a respective consumer to fetch and provide the respective line group from memory. The line buffer unit has programmable storage space whose information establishes line group size so that different line group sizes for different image sizes are storable in memory.Type: GrantFiled: April 27, 2020Date of Patent: November 30, 2021Assignee: Google LLCInventors: Neeti Desai, Albert Meixner, Qiuling Zhu, Jason Rupert Redgrave, Ofer Shacham, Daniel Frederic Finchelstein

Patent number: 10733956Abstract: An image processor is described. The image processor includes an I/O unit to read input image data from external memory for processing by the image processor and to write output image data from the image processor into the external memory. The I/O unit includes multiple logical channel units. Each logical channel unit is to form a logical channel between the external memory and a respective producing or consuming component within the image processor. Each logical channel unit is designed to utilize reformatting circuitry and addressing circuitry. The addressing circuitry is to control addressing schemes applied to the external memory and reformatting of image data between external memory and the respective producing or consuming component. The reformatting circuitry is to perform the reformatting.Type: GrantFiled: November 15, 2019Date of Patent: August 4, 2020Assignee: Google LLCInventors: Albert Meixner, Neeti Desai, Dilan Manatunga, Jason Rupert Redgrave, William R.

Patent number: 10719905Abstract: An apparatus is described. The apparatus includes an image processing unit. The image processing unit includes a plurality of stencil processor circuits each comprising an array of execution unit lanes coupled to a two-dimensional shift register array structure to simultaneously process multiple overlapping stencils through execution of program code. The image processing unit includes a plurality of sheet generators respectively coupled between the plurality of stencil processors and the network. The sheet generators are to parse input line groups of image data into input sheets of image data for processing by the stencil processors, and, to form output line groups of image data from output sheets of image data received from the stencil processors. The image processing unit includes a plurality of line buffer units coupled to the network to pass line groups in a direction from producing stencil processors to consuming stencil processors to implement an overall program flow.Type: GrantFiled: August 22, 2019Date of Patent: July 21, 2020Assignee: Google LLCInventors: Qiuling Zhu, Ofer Shacham, Albert Meixner, Jason Rupert Redgrave, Daniel Frederic Finchelstein, David Patterson, Neeti Desai, Donald Stark, Edward Chang, William R.

Patent number: 10706006Abstract: An image processor is described. The image processor includes a storage circuit to store segments of input image data received in a raster scan format. The image processor further includes a reformatting circuit to convert the segments of input image data into a block image format. The image processor further includes a processor comprising a two-dimensional execution lane array and a two-dimensional shift register array. The two-dimensional shift register array is to store the input image data that has been formatted into the block image format. The execution lane array is to execute instructions that operate on the image data from the two-dimensional shift register array.Type: GrantFiled: August 21, 2019Date of Patent: July 7, 2020Assignee: Google LLCInventors: Asif Khan, Jason Redgrave, Neeti Desai, David Warren
