ELECTRONIC APPARATUS INCLUDING A PLURALITY OF PROCESSORS

摘要

PURPOSE: An electronic device including plural processors is provided to efficiently perform communication between the processors by implementing an inner MCU(Micro Controller Unit). CONSTITUTION: An IPC(Inter-Processor Communication) unit(300) performs communication between processors(100). The processors include each core(111-1) and each memory(113-1). The memory includes a common buffer unit and a transmitting buffer unit. A core of a transmitting processor transmitting a multicast or unicast message writes the multicast message in the common buffer unit of the transmitting processor and writes the unicast message in the transmitting buffer unit of the transmitting processor.
