    摘要: An improved method for removing sludge and corrosion products from the interior of a heat exchanger vessel, such as a nuclear steam generator, which comprises the steps of generating a series of pressure pulses within a liquid chelate-containing chemical cleaning agent after the agent has been introduced into the interior of the vessel to create shock waves in the liquid for dislodging, dissolving and fluidizing sludge and corrosion products. The liquid chemical cleaning agent is removed from the vessel after only about 10 to 70 percent of what would have been its normal residence time without the pressure pulses. The method further includes the steps of simultaneously recirculating the chemical cleaning agent through a filter assembly during the pressure pulsing operation in order to remove fluidized sludge and corrosion products dislodged by the pressure pulsing, thereby affording them no opportunity to resettle back onto the surfaces of the heat exchanger vessel and interfere with the chemical cleaning of the vessel. The method reduces not only the time required for a particular chemical cleaning agent to effectively clean the vessel, but further reduces the number of times such chemicals need to be introduced into the vessel, which in turn results in the production of less radioactive liquid waste products.

    摘要: A computer having a cache memory and a main memory is provided with a transformation unit between the main memory and the cache memory so that at least a portion of an information unit retrieved from the main memory may be transformed during retrieval of the information (fetch) from a main memory and prior to storage in the cache memory (cache). In a specific embodiment, an instruction may be predecoded prior to storage in the cache memory. In another embodiment involving a branch instruction, the address of the target of the branch is calculated prior to storing in the instruction cache. The invention has advantages where a particular instruction is repetitively executed since a needed decode operation which has been partially performed previously need not be repeated with each execution of an instruction. Consequently, the latency time of each machine cycle may be reduced, and the overall efficiency of the computing system can be improved. If the architecture defines delayed branch instructions, such branch instructions may be executed in effectively zero machine cycles. This requires a wider bus and an additional register in the processor to allow the fetching of two instructions from the cache memory in the same cycle.

    摘要: An improved, compact model steam generator having multiple primary systems is described herein. The model steam generator of the invention is capable of simultaneously simulating a plurality of thermo-hydraulic conditions which may exist in various areas of a full-scale nuclear steam generator in order that the effect of these various conditions on the heat exchange tubes within the full-scale generator may be separately monitored. The model steam generator of the invention generally includes a boiler vessel having a primary side which houses a plurality of individually controllable primary systems, a tubesheet, a secondary side, and a plurality of sample heat exchange tubes for transferring heat between each of the individual primary systems and the secondary side of the boiler vessel. A heat flux control system connected to each of the heat sources within the primary systems allows the operator to separately adjust the heat fluxes of each of the ends of the sample tubes disposed within the secondary side of the boiler vessel. In order to reduce the longitudinal and diametrical dimensions of the primary side of the boiler vessel, the heat source used in each of the individual primary systems is preferably a single, high-intensity electrical heater formed from a coil or other high density configuration of electrical resistance wire. Moreover, each of these primary systems may be housed within the tube-receiving bores of the tube sheet of the boiler vessel in order to minimize the longitudinal dimensions of the primary side even further.

    摘要: A method and apparatus for instruction prefixing selectively reconfigures certain of the instructions in the microprocessor's instruction set so as to alter the nature of the operation performed by the instruction and/or the designation of operand or result locations accessed by the operation. A prefix instruction is inserted ahead of a "using" instruction and an operational parameter of the using instruction is modified in accordance with the contents of the prefix instruction. In one application, the prefix instruction may be used to specify a register location for storage of a result of the using instruction's operation or retrieval of an operand. In other applications, the prefix instruction may be used to modify other aspects of instruction execution.

    摘要: Methods and apparatus are provided for performing multi-gauge arithmetic operations in a microprocessor CPU. Special purpose instructions facilitate parallel processing of individual bytes or half words of data words without requiring that the processor's mode be separately controlled. A byte/half word mode flag is provided to control the "width" of narrow gauge operation. Add partial, substract partial and compare partial instructions operate on corresponding bytes or half words of two operands and return independent byte or half word results. Multiply partial instructions multiply byte or half word multiplicands by a common multiplier and return independent byte or half word products. The multi-gauge arithmetic operations of the present invention have particular application to graphics processing where repetitive operations are performed on large arrays of pixel data.

    摘要: A computer system has a memory controller that includes read buffers coupled to a plurality of memory channels. The memory controller advantageously eliminates the inter-channel skew caused by memory modules being located at different distances from the memory controller. The memory controller preferably includes a channel interface and synchronization logic circuit for each memory channel. This circuit includes read and write buffers and load and unload pointers for the read buffer. Unload pointer logic generates the unload pointer and load pointer logic generates the load pointer. The pointers preferably are free-running pointers that increment in accordance with two different clock signals. The load pointer increments in accordance with a clock generated by the memory controller but that has been routed out to and back from the memory modules. The unload pointer increments in accordance with a clock generated by the computer system itself Because the trace length of each memory channel may differ, the time that it takes for a memory module to provide read data back to the memory controller may differ for each channel. The “skew” is defined as the difference in time between when the data arrives on the earliest channel and when data arrives on the latest channel. During system initialization, the pointers are synchronized. After initialization, the pointers are used to load and unload the read buffers in such a way that the effects of inner-channel skew is eliminated.
