  • Patent number: 10852806
    Abstract: Methods and apparatus relating to techniques for a dual path sequential element to reduce toggles in data path are described. In an embodiment, switching logic causes signals for a single data path of a processor to be directed to at least two separate data paths. At least one of the two separate data paths is power gated to reduce signal toggles in the at least one data path. Other embodiments are also disclosed and claimed.

  • Publication number: 20200348897
    Abstract: In accordance with some embodiments, the render rate is varied across and/or up and down the display screen. This may be done based on where the user is looking in order to reduce power consumption and/or increase performance. Specifically the screen display is separated into regions, such as quadrants. Each of these regions is rendered at a rate determined by at least one of what the user is currently looking at, what the user has looked at in the past and/or what it is predicted that the user will look at next. Areas of less focus may be rendered at a lower rate, reducing power consumption in some embodiments.

  • Patent number: 10761898
    Abstract: Some implementations provide techniques and arrangements to migrate threads from a first core of a processor to a second core of the processor. For example, some implementations may identify one or more threads scheduled for execution at a processor. The processor may include a plurality of cores, including a first core having a first characteristic and a second core have a second characteristic that is different than the first characteristic. Execution of the one or more threads by the first core may be initiated. A determination may be made whether to apply a migration policy. In response to determining to apply the migration policy, migration of the one or more threads from the first core to the second core may be initiated.

  • Publication number: 20200241622
    Abstract: Methods and apparatus relating to techniques for avoiding cache lookup for cold cache. In an example, an apparatus comprises logic, at least partially comprising hardware logic, to receive data for a current write operation to a memory, determine a number of bits in the received data for the current write operation to the memory which have changed from a previous write operation to the memory and in response to a determination that the number of bits in the received data for the current write operation to the memory which have changed from a previous write operation to the memory exceeds a threshold, to toggle a plurality of bits in the data for the current write operation to create an encoded data set and set an indicator bit to a value which indicates that the plurality of bits have been toggled. Other embodiments are also disclosed and claimed.

  • Patent number: 10671133
    Abstract: An apparatus includes a distribution network that includes circuitry configured to receive first power from a first voltage source and second power from a second voltage source, and to deliver power to each of a plurality of electronic circuitry blocks (ECBs), including to deliver first ECB power to a first ECB and second ECB power to a second ECB. The first ECB power includes a first portion of the first power and a first portion of the second power. The apparatus also includes power management logic to dynamically adjust the power to be provided to each ECB. Responsive to a change in a first activity level of the first ECB, the power management logic is to change the first ECB power by adjustment of the first portion of the first power and adjustment of the first portion of the second power. Other embodiments are described and claimed.

  • Publication number: 20200160819
    Abstract: Methods and apparatus relating to an adaptive multibit bus for energy optimization are described. In an embodiment, a 1-bit interconnect of a processor is caused to select between a plurality of operational modes. The plurality of operational modes comprises a first mode and a second mode. The first mode causes transmission of a single bit over the 1-bit interconnect at a first frequency and the second mode causes transmission of a plurality of bits over the 1-bit interconnect at a second frequency based at least in part on a determination that an operating voltage of the 1-bit interconnect is at a high voltage level and that the second frequency is lower than the first frequency. Other embodiments are also disclosed and claimed.
