Patent number: 10290620Abstract: A semiconductor package includes a processor die (e.g., an SoC) and one or more memory die (e.g., DRAM) coupled to a ball grid array (BGA) substrate. The processor die and the memory die are coupled to opposite sides of the BGA substrate using terminals (e.g., solder balls). The package may be coupled to a printed circuit board (PCB) using one or more terminals positioned around the perimeter of the processor die. The PCB may include a recess with at least part of the processor die being positioned in the recess. Positioning at least part of the processor die in the recess reduces the overall height of the semiconductor package assembly. A voltage regulator may also be coupled to the BGA substrate on the same side as the processor die with at least part of the voltage regulator being positioned in the recess a few millimeters from the processor die.Type: GrantFiled: January 31, 2017Date of Patent: May 14, 2019Assignee: Apple Inc.Inventors: John Bruno, Jun Zhai, Timothy J.

Patent number: 9762919Abstract: Methods and apparatus for caching reference data in a block processing pipeline. A cache may be implemented to which reference data corresponding to motion vectors for blocks being processed in the pipeline may be prefetched from memory. Prefetches for the motion vectors may be initiated one or more stages prior to a processing stage. Cache tags for the cache may be defined by the motion vectors. When a motion vector is received, the tags can be checked to determine if there are cache block(s) corresponding to the vector (cache hits) in the cache. Upon a cache miss, a cache block in the cache is selected according to a replacement policy, the respective tag is updated, and a prefetch (e.g., via DMA) for the respective reference data is issued.Type: GrantFiled: August 28, 2014Date of Patent: September 12, 2017Assignee: Apple Inc.Inventors: Guy Cote, Joseph P.

Patent number: 9699481Abstract: A technique is provided for processing decoded video data to mask visual compression artifacts resulting from video compression. In accordance with this technique, a hardware block is provided for generating and adding random noise to the decoded video stream. In one embodiment, a random number is generated for each pixel of the decoded video data and compared against one or more threshold values to determine a threshold range. In such an embodiment, a noise addend value is selected based upon the threshold comparison and summed with the current pixel. While the present technique may not eliminate the compression artifacts, the addition of random noise renders the compression artifacts less noticeable to the human eye and, therefore, more aesthetically pleasing to a viewer.Type: GrantFiled: October 12, 2012Date of Patent: July 4, 2017Assignee: APPLE INC.Inventors: Haitao Guo, Sally Fung, Timothy J.
