  • Publication number: 20250004826
    Abstract: Scheduling requests of multiple processing-in-memory threads and requests of multiple non-processing-in-memory threads is described. In accordance with the described techniques, a memory controller receives a plurality of processing-in-memory threads and a plurality of non-processing-in-memory threads from a host. The memory controller schedules an order of execution for requests of the plurality of processing-in-memory threads and requests of the plurality of non-processing-in-memory threads based on a priority associated with each of the requests and a current operating mode of the system. Requests are maintained in queues at the memory controller and are individually assigned a priority level based on time enqueued at the memory controller. Requests of a different mode than a current operating mode of the system are delayed for scheduling until at least one different mode request is escalated to a maximum priority value, at which point the memory controller initiates a system mode switch.

  • Publication number: 20250005840
    Abstract: A technique for texture filtering. A transition is made from a first mipmap corresponding to a first texture resolution to a second mipmap corresponding to a second texture resolution. The first texture resolution is lower than the second texture resolution. As compared to standard trilinear filtering, initiation of the transition is delayed by an offset (or bias), which serves to delay the initial use of the second mipmap until it has been loaded. Following initiation of the transition, first and second weightings are selected with a nonlinear filter, and the system interpolates between the first mipmap and the second mipmap by applying the weightings. During an initial portion of the transition, the nonlinear filter has a slope that is higher than that of the standard trilinear filter.
