DATA COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To enable communication of data which exceed the size of a dual port memory and data communication between CPUs even if there is no sufficiently available space in the dual port memory. SOLUTION: A communication device which enables data communication between at least two CPUs (101 and 105) is provided with not-yet-transmitted data storage buffers (103 and 107) for storing data, which are not written in the ring buffers (109 and 112) of the dual port memory (104) among transmitted data.
