  • Patent number: 11972349
    Abstract: In one embodiment, a method for machine learning acceleration includes receiving instructions to perform convolution on an input tensor using a filter tensor, determining that the size of a first dimension of the input tensor is less than a processing capacity of each of multiple subarrays of computation units in a tensor processor, selecting a second dimension of the input tensor along which to perform the convolution, selecting, based on the second dimension, one or more dimensions of the filter tensor, generating (1) first instructions for reading, using vector read operations, activation elements in the input tensor organized such that elements with different values in the second dimension are stored contiguously in memory, and (2) second instructions for reading weights of the filter tensor along the selected one or more dimensions, and using the first and second instructions to provide the activation elements and the weights to the subarrays.

  • Patent number: 11954580
    Abstract: In one embodiment, a method for machine learning acceleration includes receiving, by a shared controller of a tensor processor cluster that includes multiple tensor processors, a multi-cycle instruction, determining, based on the instruction, a sequence of vector operations to be executed by the tensor processors and address information usable to determine a respective spatial partition of an input tensor on which each tensor processor is to operate when performing each vector operation. The method also includes, for each vector operation in the sequence, generating, based on the address information, a common address offset, relative to a respective base address associated with each tensor processor, at which each tensor processor is to retrieve the respective spatial partition on which the tensor processor is to operate, multicasting the common address offset to the tensor processors, and controlling the tensor processors to execute the vector operation in parallel and in lock step.

  • Patent number: 11042466
    Abstract: An approach is provided for predicting an exception during a debugging of software code before the debugging encounters the exception. During a debugging of a line number L of the code and based on an exception being predicted to be encountered at a line number M, a warning is displayed that the exception is to be encountered at the line number M, which is within a range of line numbers L+1 through L+X, where L>0 and X>1. Using a fix written in response to the predicted exception, the software code is modified. During a debugging of the line number M of the code, the modified software code is executed to avoid the predicted exception.

  • Patent number: 10761976
    Abstract: A method and apparatus is provided for wear leveling of a storage medium in an electronic device. Wear leveling is achieved by mapping each logical memory address to a corresponding physical memory address. The mapping information is consistent over an on-period of a power cycle, but changes from one power cycle to another. The mapping information, such as a key value for example, may be stored in non-volatile memory such as, for example, a correlated electron random switch (CES) storage element. The mapping may be obtained by manipulating bits of the logical address to obtain the physical address.

  • Publication number: 20200265436
    Abstract: A method and a system for processing transactions is provided. A terminal device executes a terminal action analysis on a transaction initiated at the terminal device by way of a transaction card. The terminal device compares a fraud count of the terminal device with a threshold fraud limit. If the fraud count exceeds the threshold fraud limit, the terminal device selects a first action from a set of actions for processing the transaction. When the first action is to authorize the transaction online, the terminal device transmits transaction details of the transaction to an acquirer server. The transaction details are indicative of a result of the terminal action analysis. The acquirer server generates an authorization request including a fraud indicator and updates the fraud indicator from a first value to a second value. The acquirer server communicates the authorization request, including the updated fraud indicator, to an issuer for authorization.
