    摘要： The arbitrating method is based on the classification of the users into different categories, and the assignment to all users in a category of an identical privilege level which characterizes the interruption capability of the users in the category. A task performed by a selected user in a category can only be interrupted for granting access to the resource to a user in a category having a higher privilege level. Also a normal preference level is assigned to each user within a category, which determines the selection order of the users in the category. The privilege level of a user category combined with the preference level of each user constitutes the priority level of the user. The access to the resource is granted to a selected user having the highest priority level. If at least one user having a privilege level higher than the privilege level of the selected user, makes a request for the resource, the task of the selected user is interrupted and the interrupted user is assigned an interruption preference level which is higher than the normal preference levels of all other users in the category. A new user having the highest priority level is then selected after the resource is released by the interrupting user.

    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.

    摘要翻译： 本发明涉及一种在通信系统中实现的用于在连接到不同用户的适配器之间交换数据和控制消息的协议，以及包括存储存储器，存储管理器和微处理器的共享存储器子系统。 这样的协议使得适配器能够通过使用与数据总线和地址总线相同的方式使用将存储管理器连接到所有适配器的控制线来发送和接收数据。 此外，适配器将消息分割成数据突发，其中是指定消息中的突发的大小，所有者和位置的关联控制字。 因此，当在数据总线上转移时，这些数据脉冲串可能被交错，而不需要微处理器进行路由，并且它们将根据用户在控制字中的标识被存储在存储器存储器中或从存储器存储器读取。 因此，只有共享存储器需要具有高的存储容量，而存储器和适配器的管理器可以以降低的存储容量进行操作，并且发送或访问数据突发的时间进一步得到改善。

    摘要： Apparatus for recovering lost buffer contents in a data processing system uses a memory divided into a plurality of buffers provided with buffer control blocks, through which source and destination users exchange information. A buffer management circuit is responsive to requests from users for allocating buffers to source users in order that source users may store the information to be sent to the destination users. This circuit builds buffer queues and dequeues buffers from the queues to send the information contained therein to the destination users and releases the buffers afterwards. A time mark register is settable to n different values in a predetermined order. The value of the time mark register is changed at the expiration of a time period P. Each time a buffer is allocated to one user, the current value of the time mark register is written into a time mark field of the buffer control block and a state field is set to a first value (leased). When the buffer is released, the state field is set to a second value (released). The contents of the buffer control blocks are read at regular time intervals t after period P, and the state field of every buffer control block is tested to determine whether it is set to the second value. If not so set, the time mark field is compared with the value the time mark register had at the time t-xP, where x is a number such as 1
