  • Publication number: 20240095037
    Abstract: A prefetcher for a coprocessor is disclosed. An apparatus includes a processor and a coprocessor that are configured to execute processor and coprocessor instructions, respectively. The processor and coprocessor instructions appear together in code sequences fetched by the processor, with the coprocessor instructions being provided to the coprocessor by the processor. The apparatus further includes a coprocessor prefetcher configured to monitor a code sequence fetched by the processor and, in response to identifying a presence of coprocessor instructions in the code sequence, capture the memory addresses, generated by the processor, of operand data for coprocessor instructions. The coprocessor is further configured to issue, for a cache memory accessible to the coprocessor, prefetches for data associated with the memory addresses prior to execution of the coprocessor instructions by the coprocessor.

  • Patent number: 4062325
    Abstract: A fluid fuel boiler having a combustion chamber having an opening for introducing a combustion supporting gaseous fluid. A burner introduces a liquid fuel into the combustion chamber mixed with the gaseous fluid for combustion thereof. Water-heating flow paths are disposed circumferentially and axially of the combustion chamber. Axial hot gas flow paths deliver hot gases from a downstream portion of the combustion chamber to a plurality of nozzles for diverting some of the hot gases along axially spaced paths in a direction circumferentially of the combustion chamber. These latter hot gas flow paths are immersed in the flow paths of the water to improve heat transfer.BACKGROUND OF THE INVENTIONThis invention relates generally to boilers and more particularly to a new and improved modular boiler.

  • Patent number: 3934555
    Abstract: A modular boiler having a cylindrical combustion chamber made of three modules and a module comprising a cover and a module comprising an expansion vessel mounted coaxially on the boiler adjacent the combustion chamber at opposite ends thereof. The cover has a frustro-conical configuration with the inner walls thereof diverging from an opening in the cover toward the interior of the combustion chamber at an angle of between 15.degree. and 55.degree.. The combustion chamber is formed of three castings that define the cylindrical combustion chamber and six axial hot gas flow paths spaced circumferentially from each other and disposed axially of and radially of the combustion chamber. Hot gases from the downstream end of the combustion chamber are recirculated to the upstream end of the combustion chamber to improve the combustion.
