This disclosure relates to methods, non-transitory computer readable media, and systems that asynchronously train a machine learning model across client devices that implement local versions of the model while preserving client data privacy. To train the model across devices, in some embodiments, the disclosed systems send global parameters for a global machine learning model from a server device to client devices. A subset of the client devices uses local machine learning models corresponding to the global model and client training data to modify the global parameters. Based on those modifications, the subset of client devices sends modified parameter indicators to the server device for the server device to use in adjusting the global parameters. By utilizing the modified parameter indicators (and not client training data), in certain implementations, the disclosed systems accurately train a machine learning model without exposing training data from the client device.

Representative apparatus, method, and system embodiments are disclosed for configurable computing. A representative system includes an interconnection network; a processor; and a plurality of configurable circuit clusters. Each configurable circuit cluster includes a plurality of configurable circuits arranged in an array; a synchronous network coupled to each configurable circuit of the array; and an asynchronous packet network coupled to each configurable circuit of the array. A representative configurable circuit includes a configurable computation circuit and a configuration memory having a first, instruction memory storing a plurality of data path configuration instructions to configure a data path of the configurable computation circuit; and a second, instruction and instruction index memory storing a plurality of spoke instructions and data path configuration instruction indices for selection of a master synchronous input, a current data path configuration instruction, and a next data path configuration instruction for a next configurable computation circuit.

Systems, methods, and apparatus for line multiplexed serial interfaces are disclosed. A method performed by a transmitting device includes asserting a stop condition on a wire of a serial data link by driving the wire to a first voltage level for a first period of time that is less than a duration of the stop condition, monitoring the wire after the first period of time, determining that flow-control has been asserted when the wire remains at a second voltage level for a second period of time that exceeds a minimum period of time defined for flow-control pulses and after the first period of time has elapsed, refraining from transmitting data on the wire while flow-control is asserted, and transmitting data on the wire when flow-control is de-asserted.

An apparatus includes a plurality of output ports and a processor. The output ports may each be configured to connect to a respective trigger device and generate an output signal to activate the respective trigger device. The processor may be configured to determine a number of the trigger devices connected to the output ports, determine a timing between each of the number of the trigger devices connected, convert the timing for each of the trigger devices to fit a standard timing using offset values specific to each of the trigger devices and perform a trigger routine to trigger the output signal for each of the trigger devices connected. The trigger routine may activate each of the trigger devices connected according to an event. The offset values may delay triggering the trigger devices to ensure that the trigger devices are sequentially activated at intervals that correspond consistently with the standard timing.

A method for stack timing adjustment for serial communications is provided. The method includes receiving a USB communication, decoding the USB communication into UART frames, and adjusting the timing of the UART frames according to a serial protocol.

In a data processing device including two sets of circuit pairs which are respectively duplicated in two clock domains which are asynchronous to each other, an asynchronous transfer circuit that transfers a payload signal is provided between the two sets of circuit pairs. The asynchronous transfer circuit includes two sets of a pair of bridge circuits which are respectively connected to the two sets of circuit pairs, and asynchronously transfers the payload signal and a control signal indicating a timing at which the payload signal is stable on a reception side. The two sets of a pair of bridge circuits and the payload signals can be duplicated, but the control signal is not duplicated, and the received payload signal is used for timing control to supply an expected same time difference, to the pair of duplicated circuits. This enables asynchronous transfer between circuits duplicated in the asynchronous clock domains.

Sideband signaling in Universal Serial Bus (USB) Type-C communication link allows multiple protocols that are tunneled through a USB link, where sideband signals may be provided through the sideband use (SBU) pins. Further, the SBU pins may be transitioned between different modes of sideband signals. In particular, signals in an initial mode may indicate a need or desire transition to a second mode. After a negotiation, linked devices agree to transition, the two devices may transition to the second mode. By providing this inband sideband signaling that allows mode changes, more protocols can be tunneled with accompanying sideband signaling and flexibility of the USB link is expanded.
