  • Patent number: 9459009
    Abstract: Colorless distributed combustion (CDC) reactors or green combustion gas turbine combustors having a combustion chamber are presented for improved performance of gas turbine combustion engines. The combustors are configured and designed for providing a superior pattern factor (uniform thermal field in the combustion zone) and a reduction or complete elimination of pollutants emission from the combustor (i.e., zero emission gas turbine combustor) and uniform thermal field in the entire combustion zone to provide significantly improved pattern factor. Colorless distributed combustion is achieved with fuel and air entering the combustion chamber via one or more injection ports as non-premixed, or premixed. Rectangular, cylindrical, stadium and elliptical shaped combustors are presented with injection ports and exit ports located in various locations of the combustors.

  • Patent number: 8449860
    Abstract: Method and system are presented for the combustion of hydrogen sulfide mixed with other gases for simultaneous recovery of sulfur and energy from hydrogen sulfide at higher efficiency. The amounts and velocity of the hydrogen sulfide into the reactor is selected in such a way that it is not possible to burn the hydrogen sulfide in a normal thin reaction zone during its combustion. The injected hydrogen sulfide gas is mixed in a thermal reactor with fresh air and hot active combustion gases in the reactor on account of internal jet pump effect and self-induced entrainment. The reaction is exothermic so that the chemical energy present in hydrogen sulfide is recovered together with the sulfur. Various reactors are shown capable of controlling the formation of a thermal distribution flow pattern based on the position, and position and direction (and other factors) regarding fluid introduction within a combustion chamber of the reactors.

  • Patent number: 5870599
    Abstract: Streaming buffer renaming for memory accesses issued by a microprocessor to an external memory via a system bus allows up to N fetch accesses at any one time for M physical streaming buffer locations, where N is greater than M. When a fetch within the processor misses the instruction cache, the fetch address is placed in the streaming buffer. When the data has been fetched from the external memory, it is returned to the streaming buffer and placed into one of the M physical buffer locations. The data within the streaming buffer is returned to the instruction cache of the processor only if it is to be used in accordance with the computer program being executed.

  • Patent number: 5715428
    Abstract: A computer system comprising a plurality of caching agents with a cache hierarchy, the caching agents sharing memory across a system bus and issuing memory access requests in accordance with a protocol wherein a line of a cache has a present state comprising one of a plurality of line states. The plurality of line states includes a modified (M) state, wherein a line of a first caching agent in M state has data which is more recent than any other copy in the system; an exclusive (E) state, wherein a line in E state in a first caching agent is the only one of the agents in the system which has a copy of the data in a line of the cache, the first caching agent modifying the data in the cache line independent of other said agents coupled to the system bus; a shared (S) state, wherein a line in S state indicates that more than one of the agents has a copy of the data in the line; and an invalid (I) state indicating that the line does not exist in the cache.

  • Patent number: 5687338
    Abstract: A method and apparatus for instruction refetch in a processor is provided. To ensure that a macro instruction is available for refetching after the processor has handled an event or determined a correct restart address after a branch misprediction, an instruction memory includes an instruction cache for caching macro instructions to be fetched, and a victim cache for caching victims from the instruction cache. To ensure the availability of a macro instruction for refetching, the instruction memory (the instruction cache and victim cache together) always stores a macro instruction that may need to be refetched until the macro instruction is committed to architectural state. A marker micro instruction is inserted into the processor pipeline when an instruction cache line is victimized. The marker specifies an entry in the victim cache occupied by the victimized cache line.

  • Patent number: 5608885
    Abstract: A circuit and method for supplying a block of instruction code to an instruction buffer for an instruction decoder. A block of instruction code is fetched and input through a buffer input. A first instruction buffer and a second instruction buffer are coupled to the buffer input to store the block of instruction code. The output of the instruction buffers and a bypass bus coupled to the buffer input are input into an instruction buffer multiplexer. The instruction buffer multiplexer selects among the three inputs and outputs two blocks of instruction code to a rotator. The rotator receives an input pointer indicative of an initial byte. The rotator outputs a block of instruction code beginning at the initial byte to an instruction decoder.

  • Patent number: 5604877
    Abstract: A method and apparatus for resolving Return From Subroutine instructions in a computer processor are disclosed. The method and apparatus resolve Return From Subroutine instructions in four stages. A first stage predicts Call Subroutine instructions and Return From Subroutine instructions within the instruction stream. The first stage stores a return address in a return register when a Call Subroutine instruction is predicted. The first stage predicts a return to the return address in the return register when a Return From Subroutine instruction is predicted. A second stage decodes each Call Subroutine and Return From Subroutine instruction in order to maintain a Return Stack Buffer that stores a stack of return addresses. Each time the second stage decodes a Call Subroutine instruction, a return address is pushed onto the Return Stack Buffer. Correspondingly, each time the second stage decodes a Return From Subroutine instruction, a return address is popped off of the Return Stack Buffer.
