Abstract
A communication system and method that may reduce the communication load and reduce the waste of system resources consumed for communication. Since a communication packet is generated using a packet structure most suitable for the data size and communication is performed through the generated communication packet, there is an advantage in that the communication load on the communication bus may be significantly reduced. In addition, since the information requesting device allocates a buffer corresponding to the communication packet and stores the communication packet in the allocated buffer, there is an advantage in that the buffer of the information requesting device may be prevented from being wasted.
