MICROSAR COM AUTOSAR Basic Software Modules for Communication For a gateway ECU, you do not need any additional software. The COM and PDUR BSW modules from MICROSAR COM enable routing of signals and TP or application messages. Overview of Advantages > Code and execution time optimized by application-specific configuration > Very efficient signal access via function macros > Contains important functionality of AUTOSAR Release 4.0 and many other useful extensions > Extended support for NM coordinators > NM module: OSEK NM compatibility is configurable > Supports simultaneous operation of AUTOSAR NM and OSEK NM in NM migration projects Functions The BSW modules from MICROSAR COM contain functions defined in AUTOSAR Release 3.x: > Services of the COM module organize transmission of messages according to their send type (cyclic, event-triggered, etc.). A key task is to implement bus-independent signals of the func-tional 2/12 software in PDUs. > The PDU Router (PDUR) distributes the PDUs to the bus-specific AUTOSAR communication modules, so that they can transmit the information. In the opposite direction, the PDUR receives the PDUs and routes them to the relevant services of the NM, COM or DCM modules or to other networks (gateway). > The Generic Network Management Interface (NM) bundles inter-bus network management activities of all of the ECU’s communication channels. As NM coordinator, it synchronizes wake-up and sleep of the communication channels. > Optionally, a user may use an I-PDU Multiplexer (IPDUM) in the communication stack of the ECU software. IPDUM supports multiple usage of fixed I-PDUs with variable data contents. The basic software modules (BSW) of MICROSAR COM include AUTOSAR services for ECU communication. These services can support any number of communication channels. They are bus-in-dependent and are needed in every communication stack. Per AUTOSAR architecture, they handle control and full integration in the ECU software of bus-specific communication modules from MICROSAR CAN, MICROSAR FR, MICROSAR LIN, MICROSAR IP and MICROSAR MOST. Application Areas MICROSAR COM lets users develop their functional software by a fully bus-independent approach. All necessary tasks for transmit-ting messages and for cross-bus network management activities are handled by the configurable BSW modules COM, NM, PDUR and IPDUM from MICROSAR COM.
