  • Publication number: 20150039833
    Abstract: A system and method for efficiently powering down banks in a cache memory for reducing power consumption. A computing system includes a cache array and a corresponding cache controller. The cache array includes multiple banks, each comprising multiple cache sets. In response to a request to power down a first bank of the multiple banks in the cache array, the cache controller selects a cache line of a given type in the first bank and determines whether a respective locality of reference for the selected cache line exceeds a threshold. If the threshold is exceeded, then the selected cache line is migrated to a second bank in the cache array. If the threshold is not exceeded, then the selected cache line is written back to lower-level memory.

  • Patent number: 8923507
    Abstract: The innovation supports the ability to map alpha characters entered directly into the dialer application of a smartphone. These alpha characters can be entered via a smartphone keyboard (e.g., QWERTY keyboard) and converted to the appropriate digits as mapped to a conventional telephone keypad. The resultant numerical digits can be used to prompt a network call. Additionally, the innovation can be used during an active call to respond to prompts that traditionally require 12-key mappings. This innovation allows a user to both dial a number directly via a smartphone keyboard, and filter contacts by name, in a non-modal manner.
