EMBEDDED SOFTWARE 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 > Available for AUTOSAR 3 and 4.0 (from Q3/2012) > Contains many 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 (ASR 3) and 4.0 (ASR 4.0): > 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 functional software in PDUs. > The PDU Router (PDUR) provides to the modules COM, DCM and to the complex drivers an interface to the communication mod-ules 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-independent (interface, transport protocol and network management) of the bus systems. This interface serves to transmit and receive data via PDUs. The PDUR also implements a gateway between the communication modules of the various bus systems. > The Generic Network Management Interface (NM) bundles inter-bus 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. network management activities of all of the ECUs communi-cation channels. As NM coordinator, it synchronizes wake-up and sleep of the communication channels. > The optional I-PDU Multiplexer (IPDUM) supports multiple usage of fixed I-PDUs with different data contents. 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 The following functions are optionally available: > COM: TX deadline monitoring COM: PDU Replication (for ASR 4.0) are handled by the configurable BSW modules COM, NM, PDUR and IPDUM from MICROSAR COM.
