  • Patent number: 11531884
    Abstract: A separate quantization method of forming a combination of 4-bit and 8-bit data of a neural network is disclosed. When a training data set and a validation data set exist, a calibration manner is used to determine a threshold for activations of each of a plurality of layers of a neural network model, so as to determine how many of the activations to perform 8-bit quantization. In a process of weight quantization, the weights of each layer are allocated to 4-bit weights and 8-bit weights according to a predetermined ratio, so as to make the neural network model have a reduced size and a combination of 4-bit and 8-bit weights.

  • Patent number: 8250580
    Abstract: A multi-core SOC synchronization component comprises a key administration module, a thread schedule unit supporting data synchronization and thread administration, and an expansion unit serving to expand the memory capacity of the key administration module. The key administration module stores, distributes and manages keys. When the key is assigned to a data synchronization process, the key administration module supports the data synchronization process. When the key is assigned to a thread process, the thread schedule unit performs thread administration. The expansion unit is coupled to an external memory and able to expand the memory of the key administration module. When the keys are expanded or the internal memory is insufficient, the keys are stored in the external memory.

  • Patent number: 8132002
    Abstract: A method of a fast system call is provided. First, a logical operation to compute a kernel service routine is used. Then the logical operation result is compared with ciphertext from a key register. At least one input for the logical operation is from the relevant information of the required kernel service routine. For example, the start address of the kernel service routine or the content of the start address of the kernel service routine, or combinations thereof. If the logical operation result equals to the ciphertext of the key register, a switch from a user mode to a kernel mode to read the kernel service routine is allowed. Otherwise, the central processing system executes a corresponding exceptional handler routine. Then the operating system terminates the mode switch request and reports an error to the operating system.
