摘要： This invention relates to a protocol implemented in a communication system for exchanging data and control messages between adapters to which are attached different users, and a shared memory subsystem comprising a depository storage, a manager of storage and a microprocessor. Such protocol enables the adapters to be the initiators of the transmission and reception of data by using the control lines that connect the manager of storage to all adapters in the same way as the data bus and the address bus. Moreover, the adapters slice the messages into data bursts to which are associated control words specifying the sizes, the owner and the position of the burst in the message. Consequently, those data bursts may be interleaved when transiting on the data bus without the intervention of the microprocessor for the routing, and they will be stored in or read from the depository storage according to the identification of the user in the control word. Therefore, only the shared memory needs to have a high capacity of storage, whereas the manager of storage and the adapters can operate with a reduced capacity of storage, and the time to send or to access a data burst is much more improved.

摘要： The subject distribution mechanism is used in a communication system comprising a plurality of interfaces, (10, 11 ans 12) with each interface connected to at least one user and able to receive and transmit information to said user(s) through information carrying means. It allows communications to be established between users selected by a central control unit (7) in a programmable way. The distribution mechanism comprises:
in each interface, scheduling means responsive to a common timing signal having a period T, to divide the period into n slot periods having a slot number, n being the number of users connected to that interface to which the maximum number of users are connected,
a configuration table (18) comprising n locations, each location assigned to a slot period, the central control unit writing in each location communication control information, said table being addressed by the slot numbers generated by the scheduling means to read and make available, the communication control information,
distribution buffer means (20) comprising at least a first and a second part, each part having n addressable locations, addressed by means of addressing means responsive to the communication control information provided by the configuration table during each slot period to cause each interface involved in the to be established communications during that slot period, to write the information to be transmitted in one part of the distribution buffer and the information to be received by the interface to be read from the other part of the distribution buffer at addresses derived from the communication control information and the slot number generated by the scheduling means.摘要翻译： 受试者分配机构在通信系统，包括具有连接到至少一个用户，并能够通过携带装置的信息的接收和发送信息到所述用户（一个或多个），每个接口的接口复数，（10，11个ANS 12）使用。 它允许由中央控制单元（7）在一个可编程的方式选择的用户之间建立的通信。 所述分配机构包括： - 在每个接口，调度装置响应于具有周期T，来划分期间为具有时隙号，n是用户的数量n时隙周期的公共定时信号连接到没有接口到的最大数目 的用户连接，其包括n个位置的配置表（18），每个位置分配给一个时隙期间，在每一个位置的通信控制信息的中央控制单元写入，所述表通过由所述调度产生的时隙号寻址装置读 和提供，其包括至少一个第一和一个第二部分中的通信控制信息，分配缓冲器装置（20），具有n个可寻址的位置的每个的一部分，由寻址装置响应于在由所述配置表中提供的通信控制信息，进行寻址 每个时隙期间，以使在通信期间建立到所涉及的每个接口做时隙期间，对WR 伊特的信息是反式mitted在分配缓冲器和所述信息的一部分由所述接口接收到从分配缓冲器的另一部分在从所述调度装置产生的通信控制信息，且时隙号派生地址读 ，
