Measurement specification with test setup Worst case data pattern Adoption of proven MOST25 technologies:

6 Physical Layer Smooth Transition To MOST150 Introduction of SMD technology for FOTs: State of the art reflow manufacturing process Increased interoperability of MOST150 components: Eye diagram specification Measurement specification with test setup Worst case data pattern Adoption of proven MOST25 technologies: INIC and NetServices Very stable from the beginning 6 14th MOST Interconnectivity Conference Asia, Dieter Seidl, Daimler AG

7 Network Management Improvements Implemented MOST150 standard features: Electrical Line (ECL) for wakeup Dynamic addressing Fixed boundary MOST NetServices Layer 1 msval_event_fptr(msval_e_neton) Requirement: SRIF_Timer(CLEAR) Requirement: Initialize Central Registry, By entering this task the configuration state has Node Ignore List, attribute SCS with got the value NotOK. value FALSE, attribute PROTECTED_MODE_ACTIVE with value FALSE, attribute MPR_RECEIVED with value TRUE; Initialize white, gray and black list Requirement: MOST Transceiver Address The callback function MostTransceiverAddress( Status) shall be available for the Event Log task. set to value 0x0100 Note: If the timer is cleared, the handler clearing the timer will call the Start Timer System Configuration t_waitbeforescan = 0 ms Scan. Yes Timer No t_waitbeforescan cleared? No Timeout Timer t_waitbeforescan? Test Requirement: t_waitbeforescan_min = 0 ms Yes t_waitbeforescan_typ = not defined t_waitbeforescan_max = 500 ms Requirement: Call of callback function System Configuration Scan MostSystemConfigurationScan( Status = Start). MOST Network Master Initialization General initialization requirement: The attribute PROTECTED_MODE_ACTIVE shall be initialized with the value FALSE by starting the MOST Network Master task and before executing any action described in the MOST Network Master flowcharts. Note: The implementation of the timer is optional. Requirement: Before starting the System Configuration Scan a valid MPR value must be available (therefore the attribute MPR_RECEIVED is set to the value TRUE in the first action box). Enhanced error detection: End System Configuration Scan MOST Network Master Scan ler E.g. ECL Diag, SSO, RBD I Timeout Timer t_delaycfgrequest? No Set attribute SCS to value TRUE Set NodeList to all available nodes Clear white and gray list Implementation Hint: The NodeList contains the following attributes: NODE_REQUESTED NODE_ANSWERED NODE_EMPTY_LIST_RECEIVED Yes SystemScanCounter + 1 SystemScanCounter = 1 Added Mechanism Node = First NodeList element I Start Timer t_delaycfgrequest = Check System Configuration t_delaycfgrequest1 = 500 ms 1st 20th No attempt All not No ignored nodes SystemScanCounter >= 20? answered with at least one Note: FBlockID/InstID Go on with pair? 21st Check System Configuration Yes only for not answered nodes and Yes attempt nodes, which has sent an empty FBlockIDList. Start Timer t_delaycfgrequest = t_delaycfgrequest2 = ms Set attribute SCS Requirement: to value FALSE I Call of callback function MostSystemConfigurationScan( Status = End).

10 Synchronous Channel (Audio Transmission) 18 parallel synchronous connections (entire system) 15 parallel synchronous connections of the Head Unit: 16 bit, 48 khz audio quality 1x 7.1 surround sound 10x stereo channels 1x 4 mono channel 3x mono channels 26 MBit/s synchronous bandwidth 10 14th MOST Interconnectivity Conference Asia, Dieter Seidl, Daimler AG

11 Isochronous Channel (Video Transmission) Infotainment system supports playback of 4 HD videos All videos are lip synched on all displays 2 videos are streamed from HU to RSE 2 isochr. connections for video streaming 1 additional isochr. connection for lip synching 15 MBit/s per streaming connection Support of DTCP encryption Blu-ray ready, bandwidth reserved to expand one video stream to 50 MBit/s 65 MBit/s isochronous bandwidth 11 14th MOST Interconnectivity Conference Asia, Dieter Seidl, Daimler AG

12 MOST Ethernet Protocol (MEP) Internet Communication Transmission of IP based data: Shared Internet access (HU, RSE, Wifi tethering) IP packet routing within the system MOST application layer communication: HU RSE data exchange Internet like data, e.g., HTML pages via HTTP Very large data, e.g., address book More efficient than MHP protocol 45 MBit/s packet data bandwidth 12 14th MOST Interconnectivity Conference Asia, Dieter Seidl, Daimler AG
