Abstract: A system on chip includes a secure processing unit (SPU), an artificial intelligence/machine learning accelerator (AI/ML accelerator), a memory inline cypher engine, and a central processing unit (CPU). The SPU is used to store biometrics of users. The AI/ML accelerator is used to process images, and analyze the biometrics of users. The AI/ML accelerator includes a micro control unit (MCU) for intelligently linking access identifications (IDs) to version numbers (VNs). The inline cypher engine is coupled to the AI/ML accelerator and the SPU for receiving a register file from the MCU, encrypting data received from the AI/ML accelerator, and comparing the biometrics of the users received from the SPU with the data. The CPU is coupled to the SPU and the AI/ML accelerator for controlling the SPU and the AI/ML accelerator.

Abstract: A system allocates scratchpad memory (SPM) to heterogeneous devices for neural network computing. The system executes the operations of a global optimization manager. The global optimization manager receives compilation states from compilers, which compile corresponding subgraphs of a neural network model into corresponding subcommands that run on the heterogeneous devices. The global optimization manager unifies records of a same object across different ones of the compilation states, and allocates the SPM to the subgraphs according to the unified records of the compilation states.

Abstract: A low-cost and high-accuracy threshold voltage (Vth) sensor is shown. In addition to a current mirror implemented by an operational amplifier and two metal-oxide-semiconductor field-effect transistors (MOSFETs), the Vth sensor uses an active device and a diode-connected MOSFET. The active device is provided to determine a constant current that is mirrored from the first MOSFET to the second MOSFET of the current mirror. The diode-connected MOSFET is coupled between the drain terminal of the second MOSFET and the ground terminal. The constant current flows through the diode-connected MOSFET to generate an output voltage that contains information about a threshold voltage (Vth) of a MOSFET.

Abstract: A semiconductor chip includes a first wireless communication circuit, a second wireless communication circuit, and an auxiliary path. The first wireless communication circuit includes a signal path, wherein the signal path includes a signal node. The second wireless communication circuit includes a mixer and a local oscillator (LO) buffer. The LO buffer is arranged to receive and buffer an LO signal, and is further arranged to provide the LO signal to the mixer. The auxiliary path is arranged to electrically connect the LO buffer to the signal node of the signal path, wherein the LO buffer is reused for a loop-back test function of the first wireless communication circuit through the auxiliary path.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE measures, at a first time point, a first set of reference signals to determine a first set of values corresponding to a set of CSI parameters. The UE determines value differences between the first set of values and a set of reference values corresponding to the set of CSI parameters. The UE sends a first CSI report including variation indicators indicating the value differences.

Abstract: A UE receives, from a base station, a first monitoring configuration for monitoring an artificial intelligence/machine learning (AI/ML) model for managing a set of beams. The UE measures a first subset of the set of beams. The UE performs inference using the AI/ML model based on measurements of the first subset to determine predication values of a second subset of the set of beams. The second subset is selected based on the first monitoring configuration. The UE measures the second subset of the set of beams to determine measured values of the second subset. The UE calculates one or more performance metrics based on the predication values and the measured values of the second subset. The one or more performance metrics are selected based on the first monitoring configuration.
