Abstract:
Provided is a neural network computing device including a neural network memory configured to store input data, a kernel memory configured to store kernel data corresponding to the input data, a kernel data controller configured to determine whether or not a first part of the kernel data matches a predetermined bit string, and if the first part matches the predetermined bit string, configured to generate a plurality of specific data based on a second part of the kernel data, and a neural core configured to perform a first operation between one of the plurality of specific data and the input data.
Abstract:
An apparatus and method for recovering the functionality of central processing unit core are disclosed herein. The apparatus for recovering the functionality of a central processing unit (CPU) core includes a functionality recovery buffer and a functionality recovery module unit. The functionality recovery buffer temporarily stores a value, to be stored in a register storage unit, in response to a write operation. The functionality recovery module unit performs the recovery of functionality by controlling the functionality recovery buffer when receiving a signal, indicating that a failure has been detected, from the outside.
Abstract:
The exemplary embodiments of the invention relates to fault tolerance of a cache memory which recovers an error occurred in the cache memory or reports an error. A cache memory may include a first layer cache configured to store data requested from a processor, together with a tag related to the data and parity check bits for detecting data error and tag error; a second layer cache configured to store data requested from the first layer cache, together with parity check bits and an error correction code(ECC) bit for detecting data error and tag error; and a fault tolerance unit configured to generate an error signal indicating whether the data error or tag error occurred in at least one of the first layer cache and the second layer cache is recoverable.
Abstract:
Exemplary embodiments of the present invention relate to a failure recovery apparatus of digital logic circuit and method thereof when a fault occurs in the digital logic circuit. A failure recovery apparatus according to an embodiment of the present invention comprises: a fault detection block configured to determine fault occurrence by comparing output results of a plurality of digital logic circuit which perform the same operation using a clock having a first cycle; and a failure recovery block configured to perform a failure recovery operation of the plurality of digital logic circuit by using a clock having a second cycle which is longer than the first cycle when it is determined as that a fault occurs. According to exemplary embodiments of the present invention, when a fault occurs in digital logic circuits due to external factors, it provides high reliability in failure recovery of the digital logic circuits.
Abstract:
A method and an apparatus for controlling an operation voltage of a processor core and a processor system including the same are provided. The apparatus for controlling an operation voltage of a processor core includes a voltage supplier and an operation voltage searching core. The voltage supplier supplies the operation voltage to the processor core. The operation voltage searching core requests the processor core to execute a program, and controls the operation voltage based on whether the program has been normally operated.
