Abstract: An integrated circuit includes a vector data processing unit that employs a cross-lane shuffle unit including multiplexing logic that programmably shuffles packed source lane values, each corresponding to one of a plurality of vector lanes, to different output vector result lane positions over multiple cycles. In certain implementations, in a first cycle, control logic in the cross-shuffle unit controls the multiplexing logic to select source lane values to be placed in a first group of output vector result lane positions for a vector result register; and in at least a second cycle, the same multiplexing logic is reused to select source lane values to be placed in a second group of output vector result lane positions for the vector result register wherein at least one of the selected source lane values is moved to a different result lane position. Associated methods are also presented.

Abstract: A data processing system includes a vector data processing unit that includes a shared scheduler queue configured to store in a same queue, at least one entry that includes at least a mask type instruction and another entry that includes at least a vector type instruction. Shared pipeline control logic controls a vector data path or a mask data path, based a type of instruction picked from the same queue. In some examples, at least one mask type instruction and the at least one vector type instruction each include a source operand having a corresponding shared source register bit field that indexes into both a mask register file and a vector register file. The shared pipeline control logic uses a mask register file or a vector register file depending on whether bits of the shared source register bit field identify a mask source register or a vector source register.

Abstract: A method includes detecting, with a passive infrared sensor (PIR), a level of infrared radiation in a field of view (FOV) of the PIR, generating a signal based on detected levels over a period of time, the signal having values that exhibit a change in the detected levels, extracting a local feature from a sample of the signal, wherein the local feature indicates a probability that a human in the FOV caused the change in the detected levels, extracting a global feature from the sample of the signal, wherein the global feature indicates a probability that an environmental radiation source caused the change in the detected levels, determining a score based on the local feature and the global feature, and determining that a human motion has been detected in the FOV based on the score.

Abstract: Various systems, devices, and methods for contactless sleep tracking are presented. Based on data received from a contactless sensor, such as a radar sensor, determine that a user has entered a sleep state. A transition time may be determined at which the user transitions from the sleep state to an awake state. An environmental event, based on data received from an environmental sensor, may be identified as occurring within a time period of the transition time. The user waking may be attributed to the environmental event based on the environmental event occurring within the time period of the transition time. An indication of the attributed environmental event as a cause of the user waking may be output.

Abstract: Various arrangements for performing an initial setup process of a sleep tracking device are presented. User input may be received that requests a sleep tracking setup process be performed. In response to the user input, a detection process may be performed based on data received from the radar sensor to determine whether a user is present and static. In response to the detection process determining that the user is present and static, a consistency analysis may be performed over a time period to assess a duration of time that the user is present and static. Based on the consistency analysis, sleep tracking may be activated such that when the user is detected in bed via the radar sensor, the user's sleep is tracked.

A second machine learning model can then be trained based on the second set of training data and the obtained plurality of weights from the first trained machine learning model.
