Accumulator, Method for Accumulator and Chip Circuit

Abstract

The present application provides an accumulator, a method for the accumulator and a chip circuit. The accumulator includes an accumulation execution module, a difference correction module and a first register, wherein: the accumulation execution module is used to perform accumulation operations on input data of floating point type, and the truncated data in each operation is reserved as truncation error, and the truncation error is fed back to the difference correction module; the difference correction module uses the fed-back truncation error to perform superposition calculation on the external input data, and outputs the superimposed input data to the accumulation execution module; the first register is used to buffer the accumulation result of the accumulation execution module, and the accumulation result is sent back to the accumulation execution module through a feedback channel. It is possible to improve the calculation efficiency while improving the accumulation accuracy of floating point numbers.
