Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to process touch data. An example apparatus includes machine learning accelerator circuitry to execute a machine learning algorithm on touch data from touch sensor circuitry; and determine, based on an output of the machine learning algorithm, whether a touch input corresponding to the touch data was intentional; transceiver circuitry to, after a determination that the touch input was intentional, provide touch coordinates to memory; and processor circuitry to, after the determination that the touch input was intentional: access the touch coordinates in the memory; and perform an action based on the touch coordinates.

Abstract: Described is an apparatus comprising a first interface, a second interface, a third interface, and an interconnection fabric. The first interface may transfer a first stream of data traffic. The second interface, which may be an enhanced Serial Peripheral Interface (eSPI) interface, may transfer a second stream of data traffic and a third stream of data traffic. The third interface may transfer a fourth stream of data traffic. The interconnection fabric may couple the first interface to the second interface and may couple the second interface to the third interface. The second interface may initiate a transfer of an outbound data stream from one of the second stream of data traffic or the third stream of data traffic based on an available-space credit indicator. The second interface may receive an inbound data stream based upon the outbound data stream.

The first vPhy circuit is configured to generate the first data toggle signal based on a signal received from the host for transmission to the device. The second vPhy circuit is configured to generate the second data toggle signal based on signal received from the device for transmission to the host.

Abstract: In one embodiment, a system includes a host system-on-chip (SoC) comprising vision processing circuitry and a camera connected to the host SoC through an Inter-Integrated Circuit (I3C) bus. The camera includes circuitry to generate image data and transmit an interrupt signal to the host SoC over the I3C bus indicating the image data is ready for transfer. The host SoC vision processing circuitry is to transmit a read message to the camera over the I3C bus based on the interrupt signal and receive a set of line payload packets including the image data over the I3C bus based on the read message.

Abstract: System and techniques for selectable clock sources are described herein. An electronic device includes an oscillator for a first clock signal and a tap on an input signal line to a resonator for the oscillator. The tap enables receipt of a second clock signal from an external oscillator. The electronic device includes mode selection circuitry to receives a signal from a tap to an existing input line to the electronic device. The mode selection circuitry uses this signal to select the oscillator output as the clock source or the tap on the input signal line as the clock source.

Abstract: Techniques and mechanisms for providing on-chip link control functionality to facilitate emulation of a communication. In an embodiment, an integrated circuit (IC) chip includes a physical layer (PHY) which supports communication compatible with a high-speed serial interface standard. A link controller of the IC chip is coupled between the PHY and an interconnect architecture which variously couples a host and other resources of the IC chip to each other. A test controller of the IC chip signals a test mode to implement a loopback path of the link controller in lieu of one or more functional paths for communication with the PHY. In another embodiment, signal output by the loopback path emulate a communication from a resource other than the test controller.

Other examples may be described.

Abstract: Techniques and mechanisms to modify packet information in support of on-chip test functionality. In an embodiment, an integrated circuit (IC) chip includes a protocol stack to receive and process packetized information—e.g., where the processing of at least one isochronous timestamp packet (ITP) includes circuitry of the protocol stack replacing non-deterministic data of the ITP with substitute information. A deterministic nature of the substitute information enables the subsequent generation of corresponding signature information which can be used in an evaluation of circuit performance. In another embodiment, the ITP packet is modified at a transaction layer of the protocol stack, and the signature information is determined with an accumulator circuit which is part of another layer of the protocol stack.
