Abstract: 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 standardsized 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.

Abstract: A digital video tape recorder includes a rotary drum ( d ) that has a leading head ( a ) and a trailing head ( b ) mounted thereon for recording video signals in respective slanting tracks (A, B) scanned on the tape (T) while the tape is advanced. Each of the tracks (A, B) includes, in sequence in the scanning direction of the respective head, a first auxiliary recording area (AU1), a second auxiliary recording area (AU2) and a video signal recording area (VI). The heads ( a ,  b ) are displaced with respect to each other on the drum ( d ) in the scanning direction by a distance (GL) that is less than the distance (K) in the scanning direction between an ending edge ( e ) of the first auxiliary recording area (AU1) of the track (B) formed by the trailing head ( b ) and a starting edge ( s ) of the video recording area (VI) of the track (A) formed by the leading head ( a ). Because of the arrangement of the heads, after-recording of audio signals in the first auxiliary recording area (AU1) by the trailing head ( b ) is completed before the leading head ( a ) begins reproduction of video signals. This prevents cross-talk from the audio recording signal that would disrupt the reproduced video signal, whereby a satisfactory picture can therefore be reproduced during after-recording of audio signals.

Abstract: Methods and apparatus are described for simultaneously acquiring time-domain ( e.g. , compressional) and frequency-domain ( e.g. , monopole Stoneley and/or dipole shear) borehole logs which are separated by frequency filtering. Monopole (Stoneley) data and dipole (shear) data are acquired simultaneously using discrete-frequency sonic emission, preferably at distinct frequencies to avoid cross-mode interference. A preferred embodiment combines discrete-frequency dipole sonic emission at low frequency (up to 5 kHz) to log formation shear wave, high frequency (5 to 30 kHz) time-domain monopole emission with first-motion detection to log formation compressional wave, and discrete-frequency monopole emission at low frequency (below 5 kHz) to log borehole Stoneley wave. The measurements of compressional, shear and Stoneley can be transmitted uphole using a small telemetry bandwidth. Benefits include higher logging speed, acquisition of all three measurements in a single logging run, real-time acquisition and processing of the three measurements, and a reduced telemetry load which allows a tool making the three measurements to be combined with other logging tools.

Abstract: A magnetic yoke for a crucible induction furnace is proposed, having a rod-shaped laminate (sheet-metal) stack (9, 19), which is suitable for guiding the magnetic flux produced by the furnace coil (3) of the crucible induction furnace (1) and consists of a multiplicity of individual laminates which are electrically insulated from one another. On its main surface facing the furnace coil (3), the laminate stack (9, 19) is shaped such that it is divided into three parts in such a manner that a central region of the laminate stack can be positioned very close to the furnace coil, while the distance between the edges of the individual laminates of the laminate stack and the furnace coil in the two side regions adjacent to the central region of the laminate stack increases towards the edge, so that acute-angled sectors which are free of laminates are formed parallel to the furnace axis in the two edge regions of the yoke pointing towards the furnace coil. This prevents high specific power being introduced at points in the edge regions of the magnetic yoke and makes the temperature distribution within the yoke uniform. <IMAGE>

Abstract: A data processing system preserves the contents of a volatile memory in the event of a power-loss and restores the contents upon a power-up. The system includes an AC line monitor (14) which signals when a power loss is imminent; volatile memory modules (26, 28); and a central processor (24) which executes programs in conjunction therewith. At any specific time during program execution, the volatile memory (26, 28) stores data indicative of the system's state. A backup disk drive (34, 36) is connected to each volatile memory module (26, 28) and is associated with a backup battery (38, 40). The backup battery (38, 40) is of limited capacity and only enables sufficient operation of the disk drive (34, 36) and volatile memory (26, 28) to enable a memory dump onto the disk drive (34, 36) from the volatile memory (26, 28). A logic circuit (50) is responsive to a signal from the line monitor (14) to activate the backup battery (38, 40) and to control the volatile memory module (26, 28) and the backup disk drive (34, 36) to effect a transfer of all stored data in the volatile memory (26, 28). Thus, upon a subsequent power up, a system state in existence at the time of the power loss can be reestablished by reading out the contents of each backup disk drive (34, 36) into its associated volatile memory module (26, 28).
