摘要

#CMT# #/CMT# The device i.e. communication structure (1), has function modules (4.1-4.n) for processing interface-related functions e.g. diagnosing function, such that the structure is formed as a part of an integrated circuit or as the integrated circuit. A master unit (2) and a number of module specific or module oriented node units (3.1-3.n) are provided corresponding to a number of the functional modules associated to the structure. The master unit includes a number of signal inputs (SI1-SIn) and request to send inputs (RQ1-RQn) corresponding to the number of the functional modules. #CMT# : #/CMT# An independent claim is also included for a method for exchange of data between function modules of an integrated circuit. #CMT#USE : #/CMT# Device i.e. communication structure, for exchange of data between function modules such as bus module, bus controller, bus transceiver, bus management unit, processor, external interface e.g. controller area network (CAN), local interconnect network (LIN), flexray, and Ethernet, and storage unit, of an integrated circuit e.g. field programmable gate array (FPGA), an application specific integrated circuit (ASIC) for processing interface-related function e.g. protocol conversion function, network management function, diagnosing function, routing function e.g. message routing function, signal routing function, data capture routing function, signal extraction function, in a fixed wired logic (all claimed), for a control unit of a vehicle and for gateway application. #CMT#ADVANTAGE : #/CMT# The device permits internal communication between the functional modules in an internal communication network in simple, optimal and rapid manner, rapidly processes routing functions with gateway-functionalities, reduces routing latency period when the device is used in a system with security-relevant function such as system for guiding of steering intervention. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block representation of an internal communication network and/or a communication structure including a master unit and multiple node units as an integrated circuit.
