Abstract
The present disclosure discloses a method and device for data transmission between register files. The method includes that: data in a source register file are read at a Stage i of a pipeline; and the read data are transmitted to a destination register file using an idle instruction pipeline. With the method of the present disclosure, data and mask information are transmitted using an idle instruction pipeline, without addition of extra registers for data and control information buffering, thus reducing logic consumption as well as increasing utilization of an existing functional unit.
