摘要： 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.

摘要： 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.

摘要： In one embodiment, a processor comprises a plurality of instruction buffers, an instruction cache coupled to supply instructions to the plurality of instruction buffers, and a cache miss unit coupled to the instruction cache. Each of the plurality of instruction buffers is configured to store instructions fetched from a respective thread of a plurality of threads. The cache miss unit is configured to monitor cache misses in the instruction cache. Particularly, the cache miss unit is configured to detect which of the plurality of threads experience a cache miss to a cache line. Responsive to a return of the cache line for storage in the instruction cache, the cache miss unit is configured to concurrently cause at least one instruction from the cache line to be stored in each of the plurality of instruction buffers that corresponds to one of the plurality of threads which experienced the cache miss to the cache line.

摘要： A method and mechanism for managing access to a plurality of registers in a processing device are contemplated. A processing device includes multiple nodes coupled to a ring bus, each of which include one or more registers which may be accessed by processes executing within the device. Also coupled to the ring bus is a ring control unit which is configured to initiate transactions targeted to nodes on the ring bus. Each of the nodes are configured receive and process bus transaction with a fixed latency whether or not the first transaction is targeted to the receiving node. The ring control unit is configured to periodically convey idle transactions on the ring bus in order to allow nodes responding to indeterminate transactions to gain access to the bus.

摘要： A method and apparatus for implementing out-of-order memory transactions in a multithreaded, multicore processor. In the present invention, circular queue comprising a plurality of queue buffers is used to store load data returned by a memory unit in response to a request issued by a processing module, such as a stream processing unit, in a processing core. As requests are issued, a destination queue buffer ID tag is transmitted as part of the request. When the request is returned, that destination number is reflected back and is used to control which queue within the circular queue will be used to store the retuned load data. Separate pointers are used to indicate the order of the queues to be read and the order of the queues to be written. The method and apparatus implemented by the present invention allows out-of-order data to be processed efficiently, thereby improving the performance of a fine grain multithreaded, multi-core processor.

摘要： 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.

摘要： 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.
