摘要： A method of and apparatus for efficiently providing video on demand services to a cable television subscriber. The provider system consists of two major subsystems. The first subsystem, called a video server, streams video to video on demand subscribers through the cable television network. The second subsystem, called the transaction server, performs virtually all remaining provider functions including, security, accounting, storage and spooling of video data, etc. The transaction server preferably uses a large scale mainframe computer. The video server subsystem may be a partitioned portion of same large scale mainframe computer.

摘要： Systems and methods for obtaining access to database files in a computing system. A method may include receiving a first call from a database management system requesting access to a database file. The method may further include transmitting a second call to an operating system interface requesting that a memory-mapped data expanse file be created. The method may also include receiving a first address representing the database file in response to successful mapping of the database file to the memory-mapped data expanse file located at the operating system interface.

摘要： An Internet checksum for use by TCP/IP is generated in a single macro-instruction called a Block Add Octets instruction. Extraneous overhead of macro-instruction looping and bit masking is eliminated by combining checksum operations into a single macro-instruction using a block add approach. The programmer specifies the address in memory and the number of double-words of message data to be added together within a single instance of the Block Add Octets instruction so that looping and jump/branch instructions are not needed. The Block Add Octets instruction fetches all octets (8-bit data segments) contained in full double words from memory and adds them into the checksum. The method handles partial double words of data, full double words, and odd numbers of double words, whereby a double word consists of four octets. The checksum is calculated using one's complement arithmetic rather than two's complement, thereby increasing the speed of checksum calculation because the "end around carry" is eliminated. The number of octets that can be added to the checksum per processor cycle is greatly increased, thereby significantly improving overall TCP/IP performance.

摘要翻译： 在一个名为Block Add Octets指令的宏指令中生成TCP / IP使用的Internet校验和。 通过使用块添加方法将校验和操作组合到单个宏指令中，消除了宏指令循环和位掩码的外部开销。 程序员在Block Add Octets指令的单个实例中指定内存中的地址和要添加在一起的消息数据的双字数，以便不需要循环和跳转/分支指令。 块添加八位字节指令从内存中获取包含在全双字中的所有八位字节（8位数据段），并将它们添加到校验和中。 该方法处理部分双字数据，全双字和奇数双字，由此双字由四个字节组成。 使用补码算术而不是二进制补码来计算校验和，从而增加校验和计算的速度，因为“结束执行”被消除。 每个处理器周期可以添加到校验和的八位字节数量大大增加，从而显着提高整体TCP / IP性能。

摘要： An apparatus for providing a computing environment in a computing system includes a first node, a second node, an operations server, and a communication link. The first node is capable of supporting a production computing environment and has a first disk storage. The second node is capable of supporting a second operational computing environment, independent of the production computing environment and has a second disk storage. The operations server manages the first and second node and can switch the production computing environment from the first node to the second node. The communications link allows communication between the first node, the second node, and the operations server. The second node can take over the production computing environment from the first node upon a failure of the first node by providing the second node with access to the first disk storage and rebooting the second node from the first disk storage. A method of switching a production computing environment from a first node, having a first disk storage, to a second node in the event of a failure on the first node includes determining if the first node had a failure and if the first node had a failure: reassigning ownership of the partition definition to the second node; restoring communications configuration on the second node; and booting the second node from the first disk storage.

摘要： A system and method for adding a queue entry containing message data to a queue shared by communicating, sequential processes includes an enqueue instruction. The enqueue instruction attaches a queue entry to either the tail or the head of the shared queue, as specified by an application programmer. Execution of the enqueue instruction includes blocking access to the queue by other processes, updating queue linkages, activating processes waiting on entries being made to the queue, monitoring interrupts, and validating the appropriate queue data structures. If desired, in lieu of adding a queue entry containing message data to the queue, the enqueue instruction inserts an event indicator into the shared queue structure, thereby providing synchronization capabilities between communicating processes.

摘要： A system and method for interprocess communication between concurrently executing, cooperating sequential processes in a digital computer system uses a shared memory queue as a mechanism for message passing and process synchronization. Data to be transferred from a sending process to a receiving process is stored in a queue entry on the shared memory queue. Hierarchical queuing allows a sending process to collect multiple message segments as entries in a local sub-queue, which is enqueued as a single entity to the shared memory queue when all message segments are present. The receiving process dequeues the sub-queue in one operation, thereby increasing the efficiency of message transfer while preventing the erroneous dequeuing of message segments when multiple receiving processes are waiting on the same shared memory queue. In this manner, the logical maximum size of a message being passed between processes is expanded.

摘要翻译： 用于数字计算机系统中的并行执行，协作顺序处理之间的进程间通信的系统和方法使用共享存储器队列作为消息传递和过程同步的机制。 要从发送进程转移到接收进程的数据存储在共享内存队列中的队列条目中。 分层排队允许发送过程收集多个消息段作为本​​地子队列中的条目，当存在所有消息段时，本地子队列作为单个实体入队到共享存储器队列。 接收处理在一个操作中出现子队列，从而提高消息传输的效率，同时防止当多个接收进程在相同的共享存储器队列上等待时消息段的错误出队。 以这种方式，扩展了在进程之间传递的消息的逻辑最大大小。

摘要： A computing system and method of executing a software program and translation of instructions for an emulated computing environment. The computing system includes a programmable circuit capable of executing native instructions of a first instruction set architecture and incapable of executing non-native instructions of a second instruction set architecture. The emulator operates within an interface layer and translates non-native applications hosted within an emulated operating system for execution. The computing system includes translated memory banks defined at least in part by the emulated operating system and capable of native execution on the programmable circuit, where the emulated operating system is incapable of execution on the programmable circuit. The computing system includes a linker configured to manage association of at least one of the one or more translated memory banks to the interface layer for native execution by the programmable circuit in place of a corresponding bank of non-native instructions.
