摘要： An arbitration method and device for a data processing system wherein N units share a common resource, to allocate the shared resource to a given unit selected from a number of units requesting access thereto.An age value is assigned to each unit and corresponds to the age of the request that will be made by the unit. During an arbitration cycle, a unit whose request will be serviced, if the shared resource becomes available, is selected, this unit being the one whose request has an age value corresponding to the oldest request. Then, the age value associated with each unit is updated when the resource is available, the age of the selected unit assuming a value corresponding to that of the most recent request, the ages of the units not selected that correspond to requests more recent than the one made by the selected unit being increased by a given quantity, and the ages of the units not selected that correspond to requests older than the one made by the selected unit remaining unchanged.

摘要翻译： 一种用于数据处理系统的仲裁方法和装置，其中N个单元共享公共资源，以将共享资源分配给从请求访问的多个单元中选择的给定单元。 年龄值分配给每个单位，并对应于单位将要进行的请求的年龄。 在仲裁周期中，如果共享资源变得可用，则其请求被服务的单元被选择，该单元是其请求具有对应于最早请求的年龄值的单元。 然后，当资源可用时，与每个单元相关联的年龄值被更新，所选单元的年龄假定与最近的请求的值相对应的值，未被选择的单元的年龄比对应于 由所选单元产生的一个增加一个给定的数量，并且未被选择的对应于所选单元所做的请求的请求的年龄保持不变。

摘要： A set of phase shifters associated with an array of radiators of an electronically scanning antenna are each controlled by a current-limiting amplifier which has an input stage in series with an electronic switch and an output stage connected to a source of operating voltage normally blocking a pair of diodes in the associated phase shifter. A feedback loop between the two amplifier stages includes another diode serving to stabilize the current flow through the phase-shifter diodes upon closure of the electronic switch by a control device and triggering of the input stage by a signal from a reference-voltage generator.
