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.
