INTER-PROCESSOR COMMUNICATION METHOD

摘要

PURPOSE: An inter-processor communication method adjusting the bus that connects inter-processor to stabilize the wireless local loop using the inter-processor communication is provided. CONSTITUTION: A first sub processor transmits a receive request signal to a main processor to transmit data, if a transmitting buffer is full(s110). The main processor always transmits a receive clock regardless of the request of the sub processor and determines the rate of the receive clock based on the through of the system and the amount of messages to be transmitted(s120). The main processor transmits a receive enable signal to the first sub processor(s130). The first sub processor transmits the receive appoint signal of 8 bit to the main processor(s140). The main processor receives the data from the first sub processor through the appointed bus(s150).
