Abstract: A system and method for arbitrating among memory requests. According to a preferred embodiment, the system comprises a global memory and a plurality of datapaths. Each datapath comprises a datapath processor for executing instructions of an instruction sequence and for providing a plurality of memory request signal types in accordance with the instructions, wherein the plurality of memory request signal types comprises instruction memory request signals, scalar memory request signals, first-in and first-out memory request signals, statistical decoder memory request signals, and block transfer memory request signals. Each datapath also comprises local memory, a global port for transferring data between the local memory and the global memory, and a dual port comprising first and second local ports for transferring data between the local memory and the datapath processor, wherein the first and second local ports permit simultaneous transfer of data between the local memory and the datapath processor.

Abstract: A method and apparatus for processing data. According to a preferred embodiment, the apparatus comprises a plurality of datapaths, each datapath comprising datapath processor, and a statistical decoder input channel device. The statistical decoder input channel device prefetches variable length encoded data from a variable length encoded data source in response to a request by a program running on a datapath processor of a datapath of the plurality of datapaths. The statistical decoder input channel device comprises a statistical decoder processor and memory for decoding the variable length encoded data to provide fixed length decoded data, and a transmission output channel for transmitting the fixed length decoded data to the datapath.

Abstract: A data processing system having execution units for executing instruction sequences determines at least two conditionals in accordance with the instructions and sets respective flags according to the determined conditionals. These flags are stored and later retrieved sequentially and the execution unit executes selected instructions of the instruction sequence according to the sequentially retrieved mask flags. These masked flags may be stored sequentially in a stack for sequential retrieval at a later time.

Abstract: This invention relates to a treated pillared clay made by the process comprising the steps of:(A) contacting at least one clay with an effective amount of at least one ammonium ion source to exchange sodium and/or calcium ions in said clay for ammonium ions to provide an ammonium-containing clay, said clay comprising metal oxides and hydroxides and having a lamellar structure with lamellar layers and interlamellar spaces disposed between the lamellar layers and exchangeable sodium and/or calcium ions occupying said interlamellar spaces;(B) contacting said ammonium-containing clay with an effective amount of at least one source of fluorine to replace at least part of the hydroxyl groups in said clay with fluorine to provide a fluorine- and ammonium-containing clay;(C) contacting said fluorine- and ammonium-containing clay with an effective amount of at least one pillaring agent to form a fluorine-containing pillared clay; and(D) contacting said fluorine-containing pillared clay with an effective amount of at l

Abstract: A single-instruction multiple-data video signal processor employs a dual-ported local memory architecture in each local memory including a dedicated port for transfers between the local memory and a global memory. A block transfer controller, in combination with the dedicated port, permit each access to the global memory by a datapath processor to be overlapped with its instruction processing, thus usually avoiding stalling of the video signal processor.

Abstract: Disclosed is a process for oxidizing a paraffin hydrocarbon containing 2 to 5 carbon atoms and no quaternary carbon atom to an olefin having the same number of carbon atoms as said paraffin by contacting said paraffin in a reaction zone with molecular oxygen and a VAPO-5 microporous molecular sieve as catalyst.
