  • Publication number: 20200192818
    Abstract: A system and method for emulating single-cycle translation lookaside buffer invalidation are described. One embodiment of a method comprises defining a translation lookaside buffer (TLB) cache marking variable comprising a first marker value and a second marker value. A context bank marker associated with a translation context bank is initiated with one of the first marker value and the second marker value. A TLB cache entry table specifies whether each of a plurality of TLB cache entries associated with the translation context bank has a corresponding entry marker set to the first marker value or the second marker value. In response to a TLB invalidate command associated with the translation context bank, the context bank marker is changed from the one of the first marker value and the second marker value to the other of the first marker value and the second marker value prior to initiating TLB invalidation.

  • Publication number: 20190139184
    Abstract: Methods, apparatuses and systems may provide for technology that processes portions of video frames in different hardware pipes. More particularly, implementations relate to technology that provides splitting of a frame into columns or rows and processing each of these in different hardware pipes and managing the dependency in hardware. Such operations may achieve this support while at the same time providing enough flexibility to use these pipes independently when the higher performance is not required.

  • Patent number: 8660063
    Abstract: A method (300) and apparatus (200) for cell detection in a wireless communication system may include acquiring (315), using a transceiver, synchronization to first radio frame boundaries of a first physical channel from a cell. The method may include attempting to decode frames (320) of a second physical channel that has second radio frame boundaries that are a multiple of the first radio frame boundaries. The method may include performing (325) a cyclic redundancy check on the frames of the second physical channel. The method may include extracting (345) predictable information from a payload from frames that fail the cyclic redundancy check.
