Title: Performance in reduced instruction set processor
Inventor: SITES RICHARD L
IPC: G06F12/08
Filed: 1991-06-27
Abstract: IMPROVING PERFORMANCE IN           REDUCED INSTRUCTION SET PROCESSOR                 ABSTRACT OF THE DISCLOSURE    A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes.  The instruction set is limited to register-to-register operations and register load/store operations.  Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions.  The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes.  By providing a conditional move instruction, many short branches can be eliminated altogether.  A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken.  Another performance improvement makes use of unused bits in the standard-sized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like.  The target can thus be prefetched before the actual address has been calculated and placed in a register.  In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed.  The processor can employ a variable memory page size, so that the entries in a translation buffer for implementing virtual addressing can be optimally used.  A granularity hint is added to the page table entry to define the page size for this entry.  An additional feature is the addition of a prefetch instruction which serves to move a block of data to a faster-access cache in the memory hierarchy before the data block is to be used.

Title: Oil well fire fighting tool
Inventor: VON BRAUN DAWN
IPC: E21B35/00
Filed: 1991-07-04
Abstract: ABSTRACT                   OIL WELL FIRE FIGHTING TOOL            In a tool for fighting oil well fires, it is known as a clamping device for securing a tubular sleave around the well casing in order that a hole may be drilled through said casing.  Once this operation has  been  completed  and withdrawn  a  second  tubular arrangement is set in its place.   Then a variety of different sealing devices can be injected into the well casing to shut and contain the flow of fluid or gases from escaping.  A variety of different stage procedures can be used especially in the case of dual barrels in a piggy back arrangement.   This procedure then enables a volume of mud, fluid or gases to be pumped into said well casing to shut,  stabilize  of control  the  well. This can be achieved by off setting the hydrostatic of the well for bottom hole control for work over proceedings, for further exploitation or a liquid emulsion that later solidifies for abandonment.

Abstract: A remote telecommunication terminal providing telecommunication functions identical to those functions provided by local telecommunication terminal directly connected to a telecommunications system via a direct standard link using a standard protocol. The remote telecommunication terminal is interconnected to the telecommunication system through an intervening switching system such as the public telephone network. One such remote telecommunication terminal is a remotetelemarketing terminal.  A remote telemarketing terminal cooperates with the telemarketing system to establish a virtual interface on the telemarketing system. The telemarketing system views this virtual interface as being identical to a physical interface such as one connected to a local telemarketing terminal via a standard link. The remote telemarketing terminal then establishes a virtual link between itself and the virtual interface on the telemarketing system. The virtual link is established on transport channels of standard links that interconnect the remote telemarketing terminal to the switching system and from the switching system to the telemarketing system. The switching system is unaware of the establishment of a virtual link on these transport channels and does not respond to signaling information on a virtual signaling channel of the virtual link. The telemarketing system controls the telemarketing functions of the remote marketing terminal by transmitting signaling information via the virtual interface and the virtual signaling channel to the remote telemarketing terminal in the same manner as the telemarketing system controls alocal telemarketing terminal via the signaling channel of the standard links connected to the local telemarketing terminals. The standard links may be eitherISDN PRI links or BRI links and the standard protocol may be the ISDN protocol.
