Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract translation: 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。

Abstract: Systems and methods for testing and validation of translated memory banks used in an emulated system are disclosed. One method includes translating one or more banks of non-native instructions into one or more banks of native instructions executable in a computing system having a native instruction set architecture. The one or more banks of non-native instructions define one or more tests of execution of a non-native instruction set architecture. The method also includes loading a memory with instructions and data defined according to the non-native instruction set architecture and addressed by the one or more tests, and triggering, by an emulator, execution of the translated one or more banks of native instructions. The method further includes, upon detection of an error during execution of the translated one or more banks of native instructions, identifying an error in execution of the non-native instruction set architecture by the computing system.

Abstract: A method of and apparatus for efficiently managing video programming services by a provider of video on demand services in response to requests from cable television subscribers. The system is controlled by a multimedia application server. Upon receipt of a request, the multimedia application server searches for the most appropriate means of satisfying the request. If the requested program is already being provided, the streaming occurs from the same video server, if capacity is available. If the program already exists in streamable form, it is streamed from that location. If the requested program must be transferred to video server memory, the available space is found to accommodate the transfer or existing programming is swapped out.

Abstract: A network input/output processing system for sending and receiving messages between a large scale computer system and associated communications networks. Executive operating system services provide access to a control table, an input queue, and an output queue stored in the computer system's main memory. A network input/output processor responds to requests by application programs, through a communications program, for receiving input from and sending output to a network, concurrently with requests to communicate with directly attached peripheral devices such as disk drives, tape drives, and printers. The network input/output processor receives initialization, reset, and termination requests via the control table. Requests to receive input are received from the input queue. Input data is stored into buffers as directed by the input request. Requests to send output are received from the output queue. Output data is read from the buffers as directed by the output request. Executive operating system services provide for control of input data transfers and output data transfers. Special purpose Instruction Processor instructions provide the capability to build control programs for processing input and output messages used by the network input/output processor to effect message transfers, thereby minimizing host instruction pathlength for communications I/O. The system architecture minimizes internal data copy between processes by using transferable buffers as communications buffers.

Abstract: A system and method for removing a queue entry containing message data from a queue shared by communicating, sequential processes includes dequeue (DEQ) and dequeue or wait (DEQW) instructions. The dequeue instruction removes a queue entry from the head of the shared queue, thereby providing access to the message data contained in the queue entry to the dequeuing process. The dequeue or wait instruction removes a queue entry from the shared queue if there is one, otherwise it suspends the execution of the dequeuing process until an entry is enqueued to the queue. If an event is selected by the dequeuing process, the dequeuing process is suspended until notification of the event is detected in the shared queue. Execution of the dequeue and dequeue or wait instructions include blocking access to the queue by other processes, updating queue linkages, deactivating processes waiting on entries or events being made to the queue, monitoring interrupts, and validating the appropriate queue data structures.

Abstract translation: 用于从通过通信的顺序进程共享的队列中去除包含消息数据的队列条目的系统和方法包括出队（DEQ）和出队或等待（DEQW）指令。 出队指令从共享队列的头部移除队列条目，从而提供对包含在队列进入出队进程的消息数据的访问。 如果有一个，出队或等待指令将从共享队列中移除一个队列条目，否则将暂停执行出队进程，直到一个条目排入队列。 如果由出队进程选择了一个事件，则在共享队列中检测到事件的通知之前暂停出队进程。 执行出队和出队或等待指令包括阻止其他进程对队列的访问，更新队列链接，停用等待队列进入的进程，监视中断和验证适当的队列数据结构。
