A method of communication media transmission. [Prior Art] An example of a communication system of the above type is the FlexRay communication system of the prior art, which has two separate channels for data transmission. Of course, there are many other communication systems that also have several separate channels for data transmission. In the FlexRay communication system, data communication in communication media, access agencies and receiving organizations and error handling is via FlexRay (Protokoll) for 5 weeks lang, which is currently based on pkxRay 6 200838204 agreement specification v2.1. FlexRay is a fast, decisive and tolerable busbar system, especially for cars. The FlexRay protocol operates in accordance with the Tine Division Multiple Access (TDMA) method, which has a fixed time slot (time slot) (Zeitschlitz, English:
timeslot)分配到用戶設備（Telinehmer，英：subscriber) (亦稱“結”或“元件”）或所要傳輸的訊息（Botschaft， 英：message )。在這些時間間隙中這些用戶設備只（排他 性地）作存取到該通訊媒體，在此，這些時間間隙以一種 固定的通訊的循環週期（Zyklus，英：CyCle )重複，因此 在一 afl息’經由該通訊媒體傳輸的時刻可準確地說出，且 匯流排存取作用決定性達成。 為了將匯流排上訊息的傳輸作用的頻寬最佳地利用， 故FlexRay將該循環週期劃分成一靜態部分及一動態部 分。在此，在靜態部分中，在一匯流排循環週期開始時， 有一固定的時間間㉟，在-動態部分，時間間隙係由動態 方式設計。其中該排他性的匯流排存取作用只對_段短時 間〔-個所謂的迷你間隙（Minisl〇t)的期間〕有可能作： 只有當-迷你間隙内作匯流排存取，料間間隙才延長: 段所需之時間。因此只有當頻寬在實際上有需： 寬才會被使用。 ’中設有二個分別的頻道以作資料傳輸。在 此FlexRay經由一個線或路二個（實體上分離 , 各頻道通訊，其f料料各最大為iGMbit々_/ F1—可用較低的資料速率操作。在此，該二頻^ 7 200838204 、泉路對應於该貫體的（physikalisch)層，特別是所謂的〇si (開放系統架構0Pen System Architecture )的層模型，人 們考慮利用該二個頻道以將訊息（B〇tscha行）以累贅 dant )以及能容許誤差的方式傳輸，其中在同時將 相同的資料經由該二頻道傳輸。如不用此方式，也可铖由 =二：道傳輸不同的訊息，如此，在該通訊系統 的貧料速率加倍。也可考慮將經由連接線路傳輸的信號 ,由该經由二線路傳輸的信號的差產生，最後一點，也可只 '用厂頻道傳輸資料，其中另一頻道不用而空著。目前將： 、lexRay應用以累贅方式設計成單頻道或雙頻道。實 的層设計成使它能夠讓信號經由線路用電方式傳輸或用 光學方式傳輸，或用其他路徑傳輸。 為了實施同步的功能，並將頻寬利用二個訊息 (Botschaft )之間的小距離而最佳化，故用戶設備在通訊 罔路中需要一共同的時間基礎，所謂的全球性（gl〇bu ) I 寸間。對於用戶設備的區域性（l〇kal )時鐘，同步訊息係 在倨環週期的靜態部分中傳輸，其中利用一特殊之演算法 (Alg0rithumus )對應於FlexRay規格將用戶設備的區域 [生時鐘時間修正，使所有的區域性時鐘對一全球性時鐘同 步運轉。 —FlexRay用戶設備包含一用戶處理機、一 FlexR叮 通Λ控制器’且在匯流排監視的情形還有一所謂的「匯流 排守衛」（Bus Guardian )。在此，用戶設備的用戶處理 機將經由通訊控制器傳輸的資料提供及處理。對於在一 8 200838204 可將訊息（Botschaft)或訊息Timeslot) is assigned to the user equipment (Telinehmer, English: subscriber) (also known as "knot" or "component") or the message to be transmitted (Botschaft, English: message). During these time slots, these user devices only (exclusively) access the communication medium, where the time slots are repeated in a fixed communication cycle (Zyklus, English: CyCle), so that in an afl The time of transmission via the communication medium can be accurately stated, and the bus access effect is decisively achieved. In order to make the best use of the bandwidth of the transmission of the message on the bus, FlexRay divides the cycle into a static part and a dynamic part. Here, in the static part, at the beginning of a bus cycle, there is a fixed time interval 35. In the -dynamic part, the time gap is designed in a dynamic manner. The exclusive bus access function is only possible for the short period of time (the period of the so-called mini-gap (Minisl〇t)]: Only when the bus is accessed in the mini-gap, the gap between the materials is Extend: The time required for the segment. So only when the bandwidth is actually needed: the width will be used. There are two separate channels for data transmission. In this FlexRay is separated by one line or two (physically separated, each channel communicates, and its f material is maximally iGMbit々_/F1), which can be operated at a lower data rate. Here, the second frequency ^ 7 200838204 , The spring road corresponds to the physikalisch layer of the body, especially the layer model of the so-called 〇si (Open System Architecture). People consider using the two channels to make the message (B〇tscha line) cumbersome dant And transmission in a manner that allows for error, wherein the same data is simultaneously transmitted via the two channels. If you don't use this method, you can also transfer different messages by =2: so that the rate of lean material in the communication system is doubled. It is also conceivable to generate a signal transmitted via the connection line from the difference of the signal transmitted via the two lines. Finally, it is also possible to transmit data only by the factory channel, in which the other channel is not used. Currently, the lexRay application is designed to be single channel or dual channel in a cumbersome manner. The real layer is designed such that it allows the signal to be transmitted electrically or optically via the line, or transmitted over other paths. In order to implement the synchronization function and optimize the bandwidth by using a small distance between two messages (Botschaft), the user equipment needs a common time base in the communication path, so-called global (gl〇bu ) I inch. For the regional (l〇kal) clock of the user equipment, the synchronization message is transmitted in the static part of the loop period, where a special algorithm (Alg0rithumus) is used to correct the area of the user equipment corresponding to the FlexRay specification. , so that all regional clocks run synchronously with a global clock. - The FlexRay user equipment consists of a user processor, a FlexR, and a controller, and in the case of bus monitoring, there is also a so-called "Bus Guardian". Here, the user processor of the user equipment provides and processes the data transmitted via the communication controller. For a message (Botschaft) or message on a 200838204

The data in a message or message is transmitted in a repeated communication cycle in a specific time interval. Examples of such usage data are, for example, Sensor measurement information 35 (throttle position, lateral and longitudinal acceleration in the car, vehicle speed, etc.) and control data of the actuator (such as the brake pressure of the brake system with electric control, the broadcast position of the automatic (four), adaptable (4) Steering system: The angular position of the directional light that supports the torque 'adaptive direction, etc. Therefore, data transmission will be used to ensure that the unit (unit of vehicle, building, machine tool, etc.) operates according to regulations.

These problems can be related to the time process in the communication system, and also the capacity and speed transmitted via the communication system. Regarding 'Under these conditions, it is possible to apply this communication system only under some conditions. In order to prevent the bus load from being affected by the application, it has been mentioned in the prior art. The communication system temporarily sets up a separate additional network, which has associated additional hardware, which is only used in the application phase. Thus, via this attachment, the network can be used to transmit the application data without thereby causing The bus load of the communication medium for transmitting and using data is changed. The additional network for the application data and the additional hardware are put into the communication system during the application phase and only during the application phase or only built into the special In the application control unit, after the application phase is over, the additional network and additional hardware are removed, resulting in significant additional costs for additional hardware and additional networks, as well as for additional hardware and additional networks. Connect and install at the beginning of the application phase and remove them at the end of the application phase. 'Because in most communication systems, individual components are placed in the car in a way that cannot be reached by outside, so this is more numb, It is annoying, so it is often impossible to overcome the great difficulty to set up additional hardware and additional networks. [The present invention] Therefore, the object of the present invention is to provide a possible way. In the application phase, a communication system can be operated in a manner that is as close to practical as possible (that is, the load of the busbar will not change due to the application) in a manner that is as simple and uncomplicated as possible. 11 .200838204 = Achieve this (four) The user equipment of the quotation of the invention in the patent range p is: the at least _ transmitting/receiving unit of the W-home device is designed to use it, the shoulder (A) to emit and/or Receiving the first type of data and using another channel), shooting and/or receiving the second data, the first data and the second data in # are different at the same time.

the citation of the third paragraph of the patent application scope. According to the invention, the communication system is designed such that it uses one of the channels (a) for transmission. Round first ': and use another channel (B) to transmit the second data, wherein the first data and the second data are different at the same time. Finally, this object is achieved according to the invention by a method according to the text of the patent application, which according to the invention is achieved by the following claims: The subsidiary of the patent scope is an advantageous further feature of the invention. The usage data is transmitted via the first channel (A), and the application data is transmitted via another channel (Bj). Patent application Nos. 2 to 5 relate to an embodiment in which the user equipment of the present invention is designed as a gateway (Gateway). Receiving data from the first user equipment via its two channels and receiving the received data via another channel; stepping to a second user equipment, the received data can be transmitted before the step in the present invention Processing, especially amplification, in the user equipment. In order to receive data from the first user equipment and send the data to the second user equipment, the user equipment has two separate transmitting and receiving units (so-called transceiving (eiVer)], One of the units is for receiving data via a channel, and the other transmitting and receiving unit is for transmitting data through another channel or further transmitting 12.200838204. In this case, it is necessary to ensure that the received data is received from the first transmitting and receiving unit. - the operation of the step to the second transmitting and receiving unit is within the user equipment of the present invention: or ensuring that the second transceiver is in common when the data is received by the first transceiver (Mith〇ren, central: m〇n It〇r). The poor materials received by the user equipment of the present invention, the poor materials received by the brother channel or the poor materials sent by the user equipment via another channel are at least different in that they are staggered in time. In the case of receiving data on one channel in the user equipment, preprocessing the data for transmission via another channel, and transmitting the received data via another channel, it is a processing day to go to the county. The data is delayed, and if the user equipment of the present invention additionally has a step of processing the received bei, the processing time is further delayed by the processing time. Further, the processing is further delayed. The information sent, even if it contains the received data itself, is different. \ Applying for patents No. 6~10 on an embodiment, the money will be transmitted by the channel (Anwendungsdaten) via the channel, and Another channel transmits the application data (Applikati〇nsdaten), this embodiment is especially used in the application phase of the communication system. In the case of transmission, another channel is vacant, in other words, one channel is not used to transmit usage data, it is used to transmit application data. In the cumbersome transmission of data usage, the transmission is limited to one channel during the application phase. An empty channel can be used to transfer application data. This can be achieved without problems, because of the cumbersome data transfer, especially for safety-related systems (such as the x_by_wire system in vehicles). There are benefits in terms of security and availability. In the application phase, the nature of this security 13 200838204 is not a serious error. Even in the data transmission hand = application phase, the situation used in data transmission is in the early days of the field. It will not be as specific as in the communication system: reach: field: = use other means or attached car = "data for the unit (example ")" use the communication in the unit 糸 ^ the measurement data It is not transmitted during the special operation of the communication system, and is only used for the application of the communication system, for example, t, the measurement data can be used: the empty channel from the user of the present invention The device was transmitted to an external test that was connected to the communication medium. If you do not use this method, you can also use the free channel to transmit the processed software state from the user of the present invention (the so-called update (deuteration)). The user equipment of the present invention is transmitted from a processed external user equipment, and the processed vehicle body complaint is stored in a storage component of the user equipment. This is also referred to as "flash". In application, it may be necessary to transfer the processed or supplemented software state to one or more of the communication systems and store therein in the storage element. In this way, the communication system can be applied to a specific range of use. It is also conceivable to transfer the specific application data during the specific operation of the communication system. This can be done via the same channel as when transferring the data or via other channels, but here, if this material is not used, the channel width is wasted. The invention will be described in detail below using the drawings. 14 200838204 [Embodiment] FIG. 1 shows a communication system of the present invention, which is generally indicated by a figure number (丨). The communication system (1) comprises a communication medium having two connection lines (2a) for data transmission via a first channel A, and two other connection lines (2b) respectively provided for them to pass a second channel b For data transmission. Of course, the communication medium (2) can also be designed as a radio connection or in infrared or other means without a line connection. Furthermore, the communication system (1) comprises a plurality of user equipments (3)' wherein its four user equipments (3a) (3b) (3c) (3d) are shown and they are connected to the communication medium (7). The user equipment (3c) is a user equipment of the present invention, which is represented by "DUT," in Figure 1 (Device Und Test). The user equipment (3d) is a tester unit. For example, it is connected to the communication medium (2) at an application stage and is therefore part of the communication system (1). The test unit (3d) is generally no longer in communication during the specific operation of the communication system. The tester unit (3d) is referred to as a scale tool (calibrati〇nt〇〇1) in Fig. i. The user equipment (3a) (3b) is a so-called other user equipment, which are similarly connected to the communication medium (2) And, therefore, part of the communication system (1). The user equipment (3a) (3b) can also theoretically be designed to function in relation to the user equipment form of the invention. The user equipment comprises at least one microcontroller (4) and at least a communication controller (5). The communication controller (5) of each user equipment (3a) (3b) (3c) (3d) comprises a first transmitting/receiving unit (6) (so-called transceiver Xcvr) for For a first channel A, and includes a second transmission/reception 15 200838204 Element (7) (transceiver Xcvr) for use by another channel b. Of course, it is also possible to use a single and the same transceiver for the first channel A and the second channel b to consider all user equipment (3a) ( 3b) (3c) (3d) is connected to the second channel A, B of the communication medium (2). In the embodiment of Fig. 1, the user equipment (3a) (3b) (3c) is via the communication controller (5) The transceiver (6) (7) is connected to the two channels A'B. The tester unit (3d) is only connected to the second channel b of the communication medium (2) via its transmitting/receiving unit (?). User equipment (3a) (3b) and (3c) are user nodes (TeUnehmerknot, subscriber mode) of the communication network (1), which exchange data with each other via the communication medium (2) in the operation of the network (1). (1) The specific operation requires the delay time (Entwurf) phase, development phase, implementation (Implementierung) phase and application phase. At the application phase, the completed communication network (丨) operates as close as possible to the real conditions. And with the default use environment [app (appUzieren)]. For this purpose, will test The unit (3d) is connected to the communication medium (2). In the application of the order, the user δ is also prepared to exchange (3a) (3b) (3c), and in addition to the use of the data, the special unit and the tester unit ( 3d) Exchange of so-called application data. The application data is used for data that is transmitted only during the application phase and is used to apply the communication system. The application data is especially for measurement data, and they display user equipment (3a) (3b) (3c) ) or the state of the functional unit connected to it. These measurements are also available to the user (3a) (3b) and/or to the tester unit (3d). The tester unit (3d) then uses the measurement data to determine the actual state of the functional part of the system, unit, or unit. Additionally, the application data contains supplemental and/or processed data programs or one of them> The software is more 16 200838204 new) and speculates that the §-type benefit unit (3d) is passed to the user equipment (3a) (3b) and / or (3c), where it is stored in a storage element (so-called " Flash, ,). According to Ben Maoming, a channel (via the channel A in Figure 1) of the communication medium (2) will be transmitted using f material, as in the case of a specific operation of the communication system (1). In addition, for example, in an application phase, the application data is transmitted via another frequency (in the example of Figure 1 via channel B). The k point has a *gp. The usage data itself can be exchanged between the user equipment (3a) (3b) (10) via the communication f (4) (2) (4) in the application phase without any influence. Since the application data is transmitted via a separate channel B, the bus load (for the usage data channel A) $ will be changed by the application. This has the benefit - ~ : : The tester unit (3d) of the communication system (1) can be close to the real "in other words", _ as in a specific application, and will not be observed and tested influentially due to the application. , implementation and application. Furthermore, via another channel B, the software data can be transferred quickly and uncomplicated to the user equipment (3a) (3b) and/or (3c) and stored there in the storage element. (The communication system (1) should be designed as a FlexRay communication system in which the data is transmitted according to the FlexRay specification. Of course, the invention can also be made into various other communication systems, which have at least two separate channels for data transmission. In the embodiment of Fig. 2, the same elements are denoted by the same reference numerals as in Fig. 2. Here, the design and the same pattern of the user equipment (3a) (3b) are the same. The user equipment (DUT, Device under test) of the present invention Here, it is represented by the figure number (3e), and differs from the user equipment (3c) of FIG. 1 in particular in that the user equipment 〇e) operates in a lane-by-channel manner and corresponds to the design. In order to further the data through other channels B 17 200838204, in the example of Figure 2, the application phase is no longer considered here, and the Nie Ning cat of the communication system (1) is from ^, ', and special. Here, the user equipment (34 (31)) (the third channel of the uniform system (2), the channel elements are all normally exchanged with each other, and the "usage data" transmitted by the frequency A is not directly Transfer to the user system (3f), but only indirectly via the user equipment (3e) of the present invention. To feed the poor material conveyed by channel A to the user equipment (10), the user equipment (3f) of the present invention does not. Using LCA, another free separate channel b of the wanted media (2), this embodiment, for example, facilitates the use of data over a large distance to the user device (3f). 2) The data transmitted by the first channel A is received by the transceiver of the channel A (6e), and further sent to the transceiver of the channel B (7, and then from the transceiver (7e) via the channel B of the communication medium (2) The line (2b) is transmitted to the user equipment (3f) where the data is received by the transceiver of the channel B (7f) and picked up to the user equipment (3f) or a unit connected to the user equipment (not shown) Further processing. The data transmitted via channel A is received in the transceiver (6e) and the received data is received. The data is further transmitted between the transceivers (7e) of channel B, and if desired, the received data can also be processed in the user equipment (the processing of the received signals specifically includes amplifying the received data, Thus, the signal can be sent to its user equipment again via channel B for a larger distance. An embodiment of the invention is shown in Fig. 3, which is constructed substantially as in the embodiment of Fig. 2, and the same components are again used in the same figure. The number indicates that the user equipment (3e), which is different from the embodiment of Fig. 2, is not directly, but is indirectly connected to the communication medium (2) via a 18 200838204 communication module (10), and therefore receives communication. The physical layer of the system (1), the structure and function of the communication module (10) are described in detail in DE 10 2〇〇5 〇 48 584. The communication module (1〇) is a communication controller in terms of hardware. The basis of the specific implementation, (4) - communication module (1) with the advantage of the present invention is that the component (10) can use the same data with a number of registers (so-called buffers). The communication module (10) can be —frequency胄A纟—specific moments ( That is, the received data received in a certain time interval is further developed in another channel B, and further transmitted at another time (ie, in another time interval). FIG. 4 shows a FlexRay communication module. The FiexRay The communication module (丨〇) is connected to the user equipment or the user processor (3e) via a connection (丨7) and connected to the communication medium (7) via the connection (16). l In order to transmit without any problem Time and data integrity are combined, so there are roughly three different settings in the FlexRay communication module. In this case, the first setting (15) is used to store at least part of the message to be transmitted '(4) It is temporary. The second setting (14) is connected between the user equipment (4) and the first setting ((7), via the connection Π7) and (10). Similarly, a third setting (1) is connected between the communication medium (2) and the first setting (15) via the connecting lines (16) and 〇9), so that the data can be presented as a part of the message (especially a heart-message message). Part of the report has the flexibility to enter the first setting (10) or output from the first setting and ensure data integrity at the optimal speed. Fig., 才丁通 afl pull group (i 〇) details of a preferred embodiment. Each connection (1 6) ~ (19) also shows its details. The second setting (10) includes an -input buffer body (7)^input buffer pin), an output buffer memory (10) (output buffer is OBF), and an interface component (consisting of two parts (four) (four)), 19 200838204, The mouth & knife module (23) is user dependent (subscriber dependent) and the second module (24) is subscriber-specific. The user-specific part module (24) (customer CPU interface CIF) will be a user-specific main CPu (3e) (that is, a customer-specific user equipment) and the FlexRay communication module (1〇) )connection. For this purpose, a bidirectional data line (36), an address line (37) and a control input port (38) are provided. There is also an r interrupt output terminal (39). The user-specific component (24) is connected to a user-related component (23) (customer CPU interface, CIF), in other words, the FiexRay communication module (1〇) [also known as the FlexRay IP module] There is a general cpu interface, the reason for the user-specific part of the component (24) (ie customer CPU interface cif) there are many different customer-specific main CPU (3e) can be connected to the general cpu interface. Thus, it must be changed according to the user equipment (3e) and only the part (24), which means that the cost can be much lower. The input buffer memory (21) and the output buffer memory (22) may be formed in a memory member or a separate memory member. Here, the input buffer memory (21) is used to temporarily store the message (B〇tschaft) for transmission to the message memory (20). The input buffer component should be designed such that it can store two complete messages (the message consists of a Header Segment (especially with a configuration data)] and a data fragment or payload (payk > ad) fragment . Here, the input buffer memory is designed as a two-part [partial buffer memory and image (shadow mask) memory (Schattenspeicher), so that the input buffer memory pi) The two parts are written in turn, or by alternately accessing, the transmission between the user equipment cpu(3e) 20 200838204 and the message memory (10) is accelerated. Similarly, the output buffer memory (9) (output buffer 0BF) is used to temporarily store the message for transmission from the message body (2〇) to the user equipment CPU, where the output buffer is also coupled to enable A complete message can be stored, which consists of a header fragment (especially those with configuration data) & a data fragment or payload fragment. Here, the output buffer memory (22) is also divided into two parts - a partial buffer memory and an image memory (SchaUenspeicher). Thus, the two parts can also be read or rotated in turn. The access is alternated to speed up the transfer between the user 1 CPU or the main CPU (3e) and the message memory (20). This second setting (14) [consisting of blocks (2丨)~^^) is connected to the first setting (15) as shown. The setting (15) is composed of a message manager (2) (message manager mHd) and a message memory (30) (message RAM). The message manager (2〇) controls the data transfer between the input buffer memory (21) and the output buffer memory (22) and the message memory (30). It evenly controls the data transfer in the other direction via the third setting (13). The message memory (30) should be designed in the form of 單埠 i (single-ported) RAM. This RAM memory stores the message or message (Botschaftsofjekt) (that is, the original data) along with the configuration and status data. The exact construction of the message memory is shown in Figure 3 of DE 10 2005 0 4 8 5 8 4 and is detailed in the description of the associated drawings, the details of which can be referred to. The third setting (13) consists of block areas (25) to (28) corresponding to the two channels A, B of the FlexRay physical layer. This setting (13) is divided into two data paths, which have two data directions, which can be seen by the connection (33) (34), where 21 200838204, , , , and a data direction of the channel A RxA and ΤχΑ are used to receive (ΜΑ) and transmit] and the channel direction (RxB and ΤχΒ). The connection (35) indicates the light input to the two-way control input, the third setting (丨3), the first buffer memory of the second channel B (25), and a second buffer memory of the channel A ( 26) Achieved. The two buffer memories (25) (26) (short buffer RAMs • RAM A and ram B) are used as scratchpads to transfer data from the first setting (15) or to the first setting 〇 5) . Corresponding to the second channel, σHaiyi, 爰 ° 丨 丨 丨 (25) (26) are each connected with an interface module (27) (28), the interface member comprises a FlexRay protocol controller or busbar The protocol controller (which consists of the escaping/receiving shift register and a ^(7) 叮 finite state machine). The second buffer memory (25) (26) thus acts as a scratchpad for transferring data between the interface components or FlexRay protocol controllers (27) and (28) and the message memory (30). Here too, the buffer fields (25) or (26) are advantageously used to store the data fields (i.e., message segments or data segments of two FlexRay messages). In addition, in the overnight module (10), (29) represents a global time unit % (G1〇balTimeUnitGTU), which is used to represent the global time network in FlexRay, ie Mikr〇tick μΤ and Makr〇tick mt. In the same way, the cycle counter (Cycle Counter) is used as the clock synchronization of the allowable error and the control of the time trend in the static and dynamic segments of the FlexRay is performed by the global time unit (29). Block area (30) represents the general system control (System Universai sue), which is used to control the operation mode of the FlexRay controller. Wakeup, startup, re-integration 22 200838204 (Reintegration) or Integration, normal operation and passive operation. Block (3 1) shows Network and Error Management (NEM) as described in the FlexRay protocol specification. Finally, the block (32) indicates the interrupt control (INT), which manages the status and error interrupt flags and controls the "interrupt output" of the user equipment CPU (3e). (3 9). In addition, the block contains an absolute and a relative timer to generate a time interrupt. c In order to communicate in a FlexRay network, the message tag or message buffer can be grouped with up to 254 data bytes. The message § Remembrance (30) is specifically a message RAM (Message RAM). For example, it can store up to 128 messages, and all functions related to the processing or management of the message are installed. Message Officer (2〇). For example, this is the acceptance filter (Akzeptanzfilterung), the message between the two FiexRay protocol controller blocks (27) and (28) and the message memory (30) (ie Message RAM), V and the sequence of the transmission. Preparation of control and configuration data or status data. The message management is (20) in the context of the present invention, relating to the transfer of the communication controller (27) of the data accessed on a channel a to the communication controller (28) so that it can pass the data through the channel B is further sent to the user equipment (3f). The external CPU, that is, an external processor of the user processor (3e), can directly access the FlexRay communication module (10) through the user equipment interface and the user-specific part (24). Most of the scratchpads are used here. These registers are used to connect the FlexRay protocol controller and interface components (27) (28). The 2008 DATE Message Manager Handler MHD (20), Global Time Unit (Global) Time Unit GTU ) (29), System Universal Controller SUC (30), Network and Error Management Unit NEM (3 1), Interrupt Controller (Interrupt Controller) INT) (32), and the access to the message Ram (ie, the message memory (30)) for configuration and control, and also show the relevant state. Figures 4 to 6 and Figure 7 of DE 10 2005 048 584 These registers are described in detail in the description of 9. Refer to these examples. / : ' The FlexRay communication module allows the FlexRay specification to be easily converted, thus simply producing an ASIC or related ASIC with associated FlexRay functionality. Microcontroller. Of course, communication mode (1 〇) can also be used to connect other user equipment of the communication system to the communication medium (2) as the user (3a) (3b) (3c) or even the tester (3d) (see Figure 1).
