Problems solved by technology

In order for a typical neural network device to handle large amounts of computation, it typically has to perform operations that read large amounts of data from memory or write large amounts of data to memory, thus potentially consuming large amounts of energy due to frequent memory accesses

Abstract

Methods and apparatus with floating point processing are provided. A method includes receiving a first floating point operand and a second floating point operand, each having an n-bit format comprising a sign field, an exponent field, and a significand field, normalizing a binary value obtained by performing arithmetic operations for fields corresponding to each other in the first and second floating point operands for an n-bit multiplication operation, determining whether the normalized binary value is a number that is representable in the n-bit format or an extended normal number that is not representable in the n-bit format, according to a result of the determining, encoding the normalized binary value using an extension bit format in which an extension pin identifying whether the normalized binary value is the extended normal number is added to the n-bit format, and outputting the encoded binary value using the extended bit format, as a result of the n-bit multiplication operation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2019-0178509 filed in the Korean Intellectual Property Office on December 30, 2019, the entire disclosure of which is incorporated herein by reference for all purposes. technical field [0003] The following description relates to methods and apparatus for floating point processing. Background technique [0004] A neural network may be a computing system implemented with reference to a hardware computing architecture. Neural network technology can analyze input data and extract effective information from it. [0005] Neural network devices often require extensive computation on complex input data. In order for a typical neural network device to handle heavy computations, it often has to perform operations that read or write large amounts of data from or to memory, thus potentially consuming a lot of energy due to frequent memory accesses. Low-pow...
