摘要： A method for adaptively adjusting state transition time in a Peripheral Component Interconnect (PCI) Express (PCIe) system and associated apparatus such as a root complex (RC) device and an endpoint device are provided. The method may include: toggling a clock request signal on a signal path coupled between the RC device and the endpoint device based on a request from the RC device or on a request from the endpoint device, wherein when the clock request signal toggles, the endpoint device transits from a first state to a second state; and toggling a reference clock signal from the RC device at a timing determined according to a training parameter among at least one predetermined parameter which is set dependent on at least one of the factors: a transition time, a restoration delay, a latency tolerance report (LTR) and a bias state, after the clock request signal toggles.

摘要： 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.

摘要： 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.

摘要： 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.
