Abstract: A processor circuit that can perform predicated vector operations is disclosed. The processor circuit may compare source and destination register locations as identified in a fetched vector instruction that specifies a predicate vector. The processor circuit may also execute the fetched vector instruction based on the predicate vector to generate an output vector. Based on a result of the comparison of the respective names of source and destination registers, the processor circuit may determine values for inactive elements in the output vector by either zeroing the inactive elements in the output vector prior to writing to the destination register or by masking a write of the inactive elements of the output vector to the destination register.

Abstract: An interrupt delivery mechanism for a system includes and interrupt controller and a plurality of cluster interrupt controllers coupled to respective pluralities of processors in an embodiment. The interrupt controller may serially transmit an interrupt request to respective cluster interrupt controllers, which may acknowledge (Ack) or non-acknowledge (Nack) the interrupt based on attempting to deliver the interrupt to processors to which the cluster interrupt controller is coupled. In a soft iteration, the cluster interrupt controller may attempt to deliver the interrupt to processors that are powered on, without attempting to power on processors that are powered off. If the soft iteration does not result in an Ack response from one of the plurality of cluster interrupt controllers, a hard iteration may be performed in which the powered-off processors may be powered on.

Abstract: Systems, apparatuses, and methods for efficiently moving data for storage and processing a compression unit within a processor includes multiple hardware lanes, selects two or more input words to compress, and for assigns them to two or more of the multiple hardware lanes. As each assigned input word is processed, each word is compared to an entry of a plurality of entries of a table. If it is determined that each of the assigned input words indexes the same entry of the table, the hardware lane with the oldest input word generates a single read request for the table entry and the hardware lane with the youngest input word generates a single write request for updating the table entry upon completing compression. Each hardware lane generates a compressed packet based on its assigned input word.

Abstract: Systems, apparatuses, and methods for coalescing interrupts temporally for later processing are described. An interrupt controller in a computing system maintains a timer for tracking an amount of time remaining after receiving an interrupt before a processor is awakened to service the interrupt. For a received interrupt with a latency tolerance greater than a threshold, the interrupt controller compares a value currently stored in the timer and the latency tolerance selected based on class. The smaller value is retained in the timer. When the timer expires, the interrupt controller sends wakeup indications to one or more processors and indications of the waiting interrupts.

Abstract: In an embodiment, a processor may implement a vector instruction set including a conditional termination instruction (CTerm). The CTerm instruction may take two source operands and compare them according to a specified condition, updating flags as a result of the instruction. The flags may be used to affect predicate vector generation to control vectorized loop execution. In an embodiment, the vector instruction set may also include a conditional termination predicate instruction (CTPred). The CTPred instruction may take a pair of predicate vectors and a set of flags as operands, and may generate: a predicate vector to control parallel processing of vector elements, and a set of flags to control further loop processing. Either instruction may be used to efficiently manage vector loops in various embodiments, or the instructions may be used together.

Abstract: In an embodiment, a processor may implement a vector instruction set including one or more compare break instructions. The compare break instruction may take a pair of operands which may be compared to determine loop termination conditions, and may output a predicate vector indicating which vector elements correspond to loop iterations that are executed and which vector elements correspond to loop iterations that are not executed. The predicate vector may serve as a predicate to vector instructions forming the body of the loop, correctly executing the specified number of iterations. The compare break instruction may be coded to check for a variety of conditions (e.g. equal, not equal, greater than, less than, etc.). In an embodiment, the compare break instruction may take a predicate operand as well, which may be combined with the predicate vector produced by the comparison operations to produce the output vector.

Abstract: The present invention provides innovative strategies for synthesizing pyrazole ring-functionalized benzodiazepinones. Alternative intermediates and high conversion strategies for forming alpha-aminobenzophenone intermediates involve a combination of aromatic acylation, displacement of electronegative leaving groups with amine, and then N-displacement strategies to produce the desired alpha-aminobenzophenone with primary amine functionality. Reaction strategies are then provided for converting alpha-aminobenzophenones to alpha-aminoamidobenzophenone intermediates with high yield and convenient reaction strategies. These alpha-aminoamidobenzophenone intermediates are then converted into benzodiazepinones. These benzodiazepinones are then converted to pyrazole ring functionalized benzodiazepinones through a series of innovative intermediates and/or reaction strategies.

Abstract: The present invention relates to methods of reducing ketal acids, salts and esters to form corresponding ketal alcohols. More particularly, the reducing methods convert the ketal acids, salts, or esters to ketal alcohols by using a reducing agent that comprises a hydride that comprises one or more alkoxy moieties. The ketal alcohol is prepared in a hydrophobic reagent. This is purified by washing the hydrophobic reagent with one or more water washes. Because the ketal alcohol has some water solubility, the water washes are back-extracted with a hydrophobic solvent to recover additional ketal alcohol from such one or more water washes. The alcohol products are useful in many applications such as intermediates in the synthesis of pharmacologically important molecules.

Abstract: The present invention advantageously provides ketal functional compounds that can be strong electrophiles under conditions compatible with ketal groups, are stable, crystalline solids at room temperature, and are much safer to handle than ketal iodides. The present invention accomplishes by incorporating aromatic sulfonyl moieties into ketal functional materials. The compounds are useful starting materials or intermediates in the synthesis of more complex organic molecules.
