摘要： A method and apparatus for controlling access to data blocks stored by addresses in a memory and concurrently accessible by a plurality of transactions is provided. The method includes the steps of receiving an address of a data block to be accessed by a first transaction, deriving from the address an access table entry corresponding to the data block where the entry includes lock data that governs access to the data block, and providing the access if permitted by the lock data, or providing the access, if not permitted by the lock data, and recording the occurrence of the access in the lock data.

摘要： A memory address translation and related control system for performing the dual functions of converting virtual memory addresses generated by the CPU into real memory addresses in a highly efficient and versatile manner and for controlling certain memory functions such as journalling. The address translation function comprises two steps, the first comprising converting the virtual address into a second virtual address or an effective address and finally the step of converting the effective address into a real memory address. The first step utilizes a set of special registers addressable by a small field to the CPU generated virtual address which converts the virtual address into an expanded form. The second or effective address is then used as the subject of the second or address translation step. To greatly enhance the translation of frequently used virtual addresses, a special set of translation tables referred to herein as a Translation Look-Aside, Buffer (TLB) contain current effective to real address translations for use where frequently referenced addresses are requested. The TLBs are addressed using a subset of the effective address whereupon the contents of the addressed TLB is examined for a match with the effective address. If the addresses match a successful address translation is possible and the real address stored in the address field of the TLB is available for system use. If the desired effective address is not present in the TLB, the page frame tables stored in main memory are accessed and searched for the desired effective address and if found the associated real address is accessed. Further a special data field is provided in both the TLBs and the page frame tables in main memory wherein a bit is provided for each line in the referenced page at a given effective to real address translation which bits may be used to indicate when a line of data has been accessed or altered.

摘要翻译： 一种存储器地址转换和相关控制系统，用于执行将由CPU产生的虚拟存储器地址以高效和通用的方式转换为实际存储器地址并用于控制某些存储器功能（例如日志记录）的双重功能。 地址转换功能包括两个步骤，第一步包括将虚拟地址转换为第二虚拟地址或有效地址，最后将有效地址转换成实际存储器地址的步骤。 第一步使用一组可由小字段寻址的特殊寄存器到CPU生成的虚拟地址，将虚拟地址转换为扩展形式。 然后将第二或有效地址用作第二或地址转换步骤的主题。 为了极大地增强频繁使用的虚拟地址的翻译，在本文中称为翻译旁边的特殊的一组转换表，缓冲器（TLB）包含当前有效的实际地址转换，以供请求经常被引用的地址使用。 使用有效地址的子集寻址TLB，由此检查寻址的TLB的内容以与有效地址的匹配。 如果地址匹配成功的地址转换是可能的，并且存储在TLB的地址字段中的真实地址可用于系统使用。 如果TLB中不存在期望的有效地址，则存储在主存储器中的页框表被访问并搜索期望的有效地址，并且如果找到，则访问相关联的实际地址。 此外，在主存储器中的TLB和页面帧表中都提供了特殊数据字段，其中在给定的有效到实际地址转换中为参考页面中的每一行提供一个位，哪些位可以用于指示何时一行 数据已被访问或更改。

摘要： A method to logically serialize a plurality of independent system events in a virtual memory data processing system. Each event causes interrupt servicing routines to be executed and requires data structures that record the status of virtual pages to be updated. The system events include the interrupt that is generated as a result of a page fault, the interrupt that is generated as a result of a paging I/O completion operation that resolves a page fault, and lastly interrupts generated in response to a supervisory call to a paging service.

摘要： A method for providing an animated transition effect between a first display state associated with a first control state of a control element rendered on a graphical user interface of a computer system, and a second display state associated with a second control state of said control element is provided. The method renders the control element in said first state and then receives at the graphic user interface, a user input event to invoke the second control state of the control element. The method evaluates a graph associated with the control element, the graph having entries each corresponding to a state of the control element, each entry comprising an event, an associated transition and a destination state, to identify a graph entry specifying a transition invoked by the input event from a current displayed first state to the destination state, being the second control state. An entry is identified corresponding to the second control state as the current state of the control element and a description of an animation associated with the specified transition is retrieved. The animation is then rendered.

摘要： A circuit and corresponding method for providing a reference voltage are presented. The circuit includes a current source having a magnitude with positive temperature correlation connected to a node, and a diode element connected between the node and ground, where the reference voltage is provided from the node. The circuit also includes a variable resistance connected to receive an input indicative of the circuit temperature and through which the diode element is connected to the node. The value of the variable resistance is adjusted based upon the circuit temperature input. The circuit is useful for application as a peripheral circuitry, such as on a flash or other non-volatile memory and other circuits requiring an on-chip reference voltage source.

摘要： An apparatus and method for use in deploying a wireless communication device is provided that includes an antenna element and a reflector secured proximate a first end of the element. The reflector includes a base, and a flexible wall with a first end positioned proximate the base extending away to a second end positioned about the element. The wall can be deformed from an original position to a deformed position where the second end is temporarily positioned proximate the element and released such that the wall returns to the original position. The method includes deforming the reflector from an original position to an altered position where portions of a rim are proximate the element. The reflector is positioned in contact with the communication device, secured in the altered position, maintained in the altered position with a reduced profile, and released such the reflector elastically returns to the original position.

摘要： A multi-port adapter and method of operation suitable for use with serial ATA devices is disclosed. An adapter includes a switch that receives input from multiple host devices and an arbiter module for assigning a priority scheme to received commands. An outstanding request table is implemented as a memory module for storing identifying information associated with commands received from multiple host devices, and a free pointers queue is maintained to track slots available in the outstanding request table. A command tracker state machine decodes incoming requests from hosts, monitors the execution by these commands by the ATA device, and updates the memory module to reflect completion of commands. Also disclosed is a storage system including an adapter of the present invention and ATA storage devices.
