DATA MULTIPLEXING TRANSMISSION DEVICE BETWEEN UPPER AND LOWER PROCESSORS IN CDMA SYSTEM AND DATA MULTIPLEXING TRANSMISSION METHOD

摘要

PURPOSE: A data multiplexing transmission device is provided to enhance a transmission efficiency by reducing a transmission time in case of a parallel data transmission operation between one upper processor and many lower processors. CONSTITUTION: One upper processor includes interrupt control part(110), a first CPU(120), and a decoder(130). The lower processor includes a dual port RAM(210), and a second CPU(220). A parallel data multiplexing communication can be performed between one upper processor and many lower processors. Therefore, in case of a parallel data transmission operation between one upper processor and many lower processor, a transmission time is reduced, and a transmission efficiency can be enhanced.
