Abstract: A method is provided of continuously varying the capacitance of a MEMS varactor having a cantilever assembly mounted on a base portion, the cantilever assembly having a first capacitance plate and a dielectric element mounted thereon, and the base portion having a second capacitance plate mounted thereon. The method includes applying a first actuation voltage to deform the cantilever assembly until the dielectric element contacts the second capacitance plate leaving a gap therebetween, and applying a second actuation voltage larger than the first actuation voltage to further deform the cantilever assembly to reduce the gap between the dielectric element and the second capacitance plate.

Abstract: Methods, systems, and media are disclosed for managing a resource managed by a mbean server having an mbean. One embodiment includes receiving a request by the application, wherein the request constitutes an action a user seeks to perform on the resource, and adding a number of instance identifier fields to an mbean descriptor file associated with the mbean. Further, the embodiment includes populating the number of instance identifier fields with an equivalent number of properties from an objectname of the resource, thereby producing a populated mbean descriptor file that identifies the resource among resources. Further still, the embodiment includes reading the mbean descriptor file after the populating, and determining, based on the reading, whether the user has an authority to perform the request. If authority exists, then an mbean method performs the action on the resource, and filters the obtained results to coincide with the user's authority.

Abstract: A method is presented for managing applications using application-based names. A naming service registers an alias name; the alias name represents a first compound name that includes an application name that is associated with an application and a deployment name that is associated with a deployment attribute that characterizes a deployment of an instance of the application. The naming service is also able to generate an application-based name associated with an application; the application-based name represents a context within a naming system, and the application-based name is a second compound name that includes the alias name. Applications are managed within a data processing system using application-based names. The first compound name can be associated with a first topology-based name that represents a first context for organizing files that are related to the instance of the application.

Abstract: A computer system includes a central processing unit and a memory management unit having a plurality of functional units, such as a memory interface unit, a remote interface unit, a cache interface unit, and a translation unit. Each functional unit has a low priority error queue for storing error information for errors having a low priority. Some functional units also have a high priority error queue for storing error information for errors having a high priority error. Based on the status of the error queues, the memory management unit prioritizes and handles errors caused by hardware failures. For low priority errors, an interrupt request signal is sent to the central processing unit. For high priority errors, a RED ALERT signal is sent to the processing unit to cause the processing unit to give immediate attention to the error. For high priority error queue overflows, a failure signal is generated which causes the system to be halted and the contents of the system to be scanned out. Thus, errors are prioritized and handled accordingly.

Abstract: A method and apparatus for performing address translation in a computer system supporting virtual memory by searching a translation lookaside buffer (TLB) and, possibly, a translation table held in memory and implemented as a B-tree data structure. The TLB is initially searched for a translation for a specified input address. If exactly one valid entry of the TLB stores a translation for the specified input address then the output address corresponding to the specified input address is determined from the contents of that entry. Otherwise, the translation table is searched for a translation for the specified input address. If two or more valid entries of the TLB store a translation for the specified input address then these entries are invalidated. If a search of the translation table is required then the method involves the retrieval from the translation table, and insertion into the TLB, of a translation for the specified input address and possibly one or more translations for other input addresses that are stored together with the translation for the specified input address in one node of the B-tree implementing the translation table. During the insertion into the TLB of a translation for a particular input address that was retrieved from the translation table it is determined if there is exactly one valid entry in the TLB that stores a translation for the particular input address. If so, then the translation retrieved from the memory is inserted into that entry, thereby avoiding the creation of multiple TLB entries for the same input address.

Abstract translation: 一种用于在支持虚拟存储器的计算机系统中执行地址转换的方法和装置，该方法和装置通过搜索保存在存储器中并实现为B树数据结构的翻译后备缓冲器（TLB）和可能的翻译表来实现。 TLB最初是搜索指定输入地址的翻译。 如果TLB的一个有效条目存储了指定输入地址的转换，则根据该条目的内容确定与指定输入地址对应的输出地址。 否则，翻译表被搜索用于指定输入地址的翻译。 如果TLB的两个或多个有效条目存储指定输入地址的转换，则这些条目无效。 如果需要对翻译表的搜索，则该方法涉及从转换表中检索并插入到TLB中的用于指定输入地址的翻译，以及可能与其中一起存储的其它输入地址的一个或多个翻译 在实现翻译表的B树的一个节点中为指定的输入地址进行翻译。 在从转换表中检索到的特定输入地址的翻译插入到TLB期间，确定TLB中是否存在恰好一个存储特定输入地址的转换的有效条目。 如果是这样，则将从存储器检索的翻译插入到该条目中，从而避免为相同的输入地址创建多个TLB条目。
