Abstract

The invention relates to an operation method of a communication node, a controller and a physical layer block. The operation method of a communication node, including a physical (PHY) layer block and a controller includes: receiving, at the controller, a wakeup signal for waking up the controller from the PHY layer block; performing, at the controller, a parting booting operation for a portion of an operating system (OS) which is required to receive data transmitted by the PHY layer block; receiving, by the controller, data transmitted by the PHY layer block; and storing, at the controller, the received data in a buffer activated according to the partial booting operation.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit and priority of Korean Patent Application No. 10-2015-0082635 filed with the Korean Intellectual Property Office (KIPO) on Jun. 11, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates generally to communication between nodes in an automotive network, and more particularly, to a technique for preventing data loss in a receiving communication node when data communication is performed between communication nodes. Background technique [0004] With the rapid digitization of vehicle components, the number and variety of electronic devices installed in vehicles has increased significantly. Electronic devices are currently used in powertrain control systems, body control systems, chassis control systems, automotive networks, multimedia systems, and the like. The powertrain control system may include an engine cont...
