METHOD FOR TRANSMITTING DATA BETWEEN PROCESSORS, COPROCESSOR FOR THE SAME METHOD, AND ELECTRICAL AND ELECTRONIC APPARATUS COMPRISING THE SAME COPROCESSOR

摘要

PURPOSE: A data transmission method between processors, a coprocessor for the data transmission method, and an electric apparatus including the coprocessor are provided to significantly improve communication speed between the process. CONSTITUTION: A host transmits data size information to a CP(Coprocessor). The transmitted data size information is stored in a transmission register(S100). The host transmits a memory assignment command to the CP. The CPU(Central Processing Unit) of the CP assigns an area for storing data to an internal memory or an external memory by software(S120). The host transmits a master mode transmission start command to the CP. Data is stored to the internal memory or the external memory through data transmission in the master mode(S140).
