In one embodiment, a processor comprising at least one translation lookaside buffer (TLB) and a control unit coupled to the TLB. The control unit is configured to track whether or not at least one update to the TLB is pending for at least one of a plurality of strands. Each strand comprises hardware to support a different thread of a plurality of concurrently activateable threads in the processor. The strands share the TLB, and the control unit is configured to delay a demap operation issued from one of the estrands responsive to the pending update, if any.

In one embodiment, a processor comprises a plurality of processor cores and an interconnect to which the plurality of processor cores are coupled. Each of the plurality of processor cores comprises at least one translation lookaside buffer (TLB). A first processor core is configured to broadcast a demap command on the interconnect responsive to executing a demap operation. The demap command identifies one or more translations to be invalidated in the TLBs, and remaining processor cores are configured to invalidate the translations in the respective TLBs. The remaining processor cores transmit a response to the first processor core, and the first processor core is configured to delay continued processing subsequent to the demap operation until the responses are received from each of the remaining processor cores.

A method for making binary predictions for a subject involves obtaining historical data for multiple subjects, the historical data including, for each subject, a feature set and a binary outcome, generating training data from the historical data, and training a predictive model using the training data to predict the outcomes based on the feature sets. The method further includes obtaining historical data including a feature set for a subject under consideration, and predicting a binary outcome for the subject under consideration, based on the feature set associated with the subject under consideration.

The present jig for guiding placement of femoral component of the implant in a knee replacement surgery (J) is a pre-assembled Jig (J) that ensures precision fit femoral implant for knee replacement based on difference of cuts in millimeters instead of the usual angle measurement in degrees. It avoids intrusion of the intramedullary canal substantially decreasing the risks of embolism. It enables the surgeon to use precise values of depth of cuts obtained from a system for obtaining optimum fit implant as described in patent application number 3896/MUM2015. This enables the surgeon to control precisely the placement of the implant in terms of flexion or extension, varus or valgus, internal or external rotation. It also enables precise placement of the four-in-one cutting block simultaneously with the distal femur cut; ensuring precise placement of knee femoral component of the knee implant. This reduces efforts and time taken during surgery.

Determining an effective address of a memory with a three-operand add operation in single execution cycle of a multithreaded processor that can access both segmented memory and non-segmented memory. During that cycle, the processor determines whether a memory segment base is zero. If the segment base is zero, the processor can access a memory location at the effective address without adding the segment base. If the segment base is not zero, such as when executing legacy code, the processor consumes another cycle to add the segment base to the effective address. Similarly, the processor consumes another cycle if the effective address or the linear address is misaligned. An integer execution unit that performs the three-operand add using a carry-save adder coupled to a carry look-ahead adder. If the segment base is not zero, the effective address is fed back through the integer execution unit to add the segment base.

A system and method for reducing branch misprediction penalty. In response to detecting a mispredicted branch instruction, circuitry within a microprocessor identifies a predetermined condition prior to retirement of the branch instruction. Upon identifying this condition, the entire corresponding pipeline is flushed prior to retirement of the branch instruction, and instruction fetch is started at a corresponding address of an oldest instruction in the pipeline immediately prior to the flushing of the pipeline. The correct outcome is stored prior to the pipeline flush. In order to distinguish the mispredicted branch from other instructions, identification information may be stored alongside the correct outcome. One example of the predetermined condition being satisfied is in response to a timer reaching a predetermined threshold value, wherein the timer begins incrementing in response to the mispredicted branch detection and resets at retirement of the mispredicted branch.

Methods and compositions for producing a solid support having a ligand immobilized on a surface thereof, e.g. a ligand array, are provided. Aspects of the methods include: providing a solid support having a bounded feature location on a surface thereof, where the bounded feature location includes a region of the surface at least partially bounded by an electromagnetic radiation modified boundary; and producing a ligand in the feature location. Also provided are systems for practicing the subject methods, as well as devices produced by the methods and methods of using such devices.
摘要:
A computer-implemented method for updating multiple data records in a database in a single transaction. The method includes searching a data model associated with the data records in the database for fields related to an objective. Once complete, a user will enter new objective values associated with the objective. The processor then performs a business rule validation of the fields found during the searching step with the new objective values entered. The report is then displayed to a user on a display. The user reviews the report and may approve the new objective values. If approved, the finalized objective values are applied to the database.

A microprocessor capable of decoding a plurality of instructions associated with a plurality of threads is disclosed. The microprocessor may comprise a first array comprising a first plurality of microcode operations associated with an instruction from within the plurality of instructions, the first array capable of delivering a first predetermined number of microcode operations from the first plurality of microcode operations. The microprocessor may further comprise a second array comprising a second plurality of microcode operations, the second array capable of providing one or more of the second plurality of microcode operations in the event that the instruction decodes into more than the first predetermined number of microcode operations. The microprocessor may further comprise an arbiter coupled between the first and second arrays, where the arbiter may determine which thread from the plurality of threads accesses the second array.
