ARITHMETIC CIRCUIT AND DATA TRANSFER METHOD

摘要

Disclosed are an arithmetic circuit and a data transfer method for the arithmetic circuit. The arithmetic circuit comprises: an arithmetic module; a data storage module which comprises at least two memories; and one or more multiplexers which are used for selecting at least one of the at least two memories and for connecting with the at least one selected memory; the arithmetic module is connected with the one or more multiplexers to allow the arithmetic module to be connected to the at least one selected memory through the multiplexers, so that the data transfer is performed between the arithmetic module and the data storage module by the multiplexers during the arithmetic process. The arithmetic circuit has no need of occupying a system bus frequently during the arithmetic process, thus congestion hardly occurs during data storage and high efficiency in operation is guaranteed.
