  • Patent number: 11908542
    Abstract: Prior knowledge of access pattern is leveraged to improve energy dissipation for general matrix operations. This improves memory access energy for a multitude of applications such as image processing, deep neural networks, and scientific computing workloads, for example. In some embodiments, prior knowledge of access pattern allows for burst read and/or write operations. As such, burst mode solution can provide energy savings in both READ (RD) and WRITE (WR) operations. For machine learning or inference, the weight values are known ahead in time (e.g., inference operation), and so the unused bytes in the cache line are exploited to store a sparsity map that is used for disabling read from either upper or lower half of the cache line, thus saving dynamic capacitance.

  • Patent number: 10739804
    Abstract: Various embodiments of the invention may be used to find a combination of voltage and frequency that results in a minimum amount of energy consumption in a digital system, including energy consumed by the system's voltage regulator (VR). The process may involve finding a separate point of minimum energy consumption for each of several different modes of the VR, where a mode is the ratio of Vin to Vout for that VR. The smallest value of those points may then be selected as the overall minimum. The process for making this determination may be performed in situ while the device is in operation, and may encompass changes in operational temperature, load, and process variations.
