Abstract: The present disclosure provides a data format conversion apparatus and method, and a buffer chip. The data format conversion apparatus is disposed on the buffer chip in a memory; a control module is disposed for sending a control instruction to a conversion module when obtaining a data copy command; and a conversion module is disposed for completing data format conversion and storage address mapping on to-be-converted data according to the received control instruction. In this way, a prior-art problem of additionally occupying computing resources and computation time of an accelerated computation unit due to a data format conversion unit disposed in the accelerated computation unit is avoided, the amount of data transmission between a main memory and a device memory is reduced without additionally occupying computing resources, and the computation precision is ensured while the computation efficiency is improved.

Abstract: Embodiments of the present invention provide a signal processing method and apparatus. The method includes: performing M-way filtering on an input signal to obtain M filtered signals, performing extraction on M filtered signals separately to obtain M extracted signals, performing fast Fourier transform (FFT) on the M extracted signals separately to obtain M frequency-domain signals, and finally determining output signals according to the M frequency-domain signals. According to the embodiments of the present invention, signal filtering and extraction are performed and then FFT is performed.
