    Abstract: An acute kidney injury predicting system and a method thereof are proposed. A processor reads the data to be tested, the detection data, the machine learning algorithm and the risk probability comparison table from a main memory. The processor trains the detection data according to the machine learning algorithm to generate an acute kidney injury prediction model, and inputs the data to be tested into the acute kidney injury prediction model to generate an acute kidney injury characteristic risk probability and a data sequence table. The data sequence table lists the data to be tested in sequence according to a proportion of each of the data to be tested in the acute kidney injury characteristics. The processor selects one of the medical treatment data from the risk probability comparison table according to the acute kidney injury characteristic risk probability.

  • Patent number: 9170817
    Abstract: Some microprocessors check branch prediction information in a branch history table and/or a branch target buffer. To check for branch prediction information, a microprocessor can identify which instructions are control flow instructions and which instructions are non control flow instructions. To reduce power consumption in the branch history table and/or branch target buffer, the branch history table and/or branch target buffer can check for branch prediction information corresponding to the control flow instructions and not the non control flow instructions.

  • Patent number: 8953497
    Abstract: In mesh networks having multiple nodes that communicate data to and from each other, a great number of data transmissions may be initiated and carried out to get data to a proper processing node for execution. To get data where it needs to go (e.g., the proper destination node), a routing algorithm is used to define a set of rules for efficiently passing data from node to node until the destination node is reached. For the purpose of assuring that all data is properly transferred from node to node in a reasonably efficient manner, a routing algorithm may define subsets of nodes into regions and then send data via the regions. Even greater overall efficiency may be realized by recognizing specific adjacency relationships among a group of destination nodes and taking advantage of such adjacencies by rerouting data through regions other than the region in which a destination node resides.

  • Patent number: 8521991
    Abstract: A technique for selecting instructions for execution from an issue queue at multiple function units while reducing the chances of instruction collisions. In an embodiment, each function unit in a processor may include a selection logic circuit that selects a specific instruction from the issue queue for execution. In order to avoid instruction collision, a function unit may have a selection logic circuit that may select two instructions from an instruction queue: one according to a first selection technique and one according to a second selection technique. Then, by comparing the instruction selected by the first selection technique to the instruction selected by the selection logic circuit of another function unit, the instruction selected by the second technique may be used instead if there will be an instruction collision because the instruction selected by the first selection technique is the same as the instruction selected at a different function unit.

  • Patent number: 8370607
    Abstract: A system for recovering an architecture register mapping table (ARMT). The system includes a first number of collection circuits and decode circuits, a second number of selection circuits, and an enable circuit. Information related to the mapping between each physical register and an appropriate architecture register is obtained from a physical register mapping table (PRMT) by one and only one collection circuit during only one of a fourth number of instruction cycles. Each decode circuit has its input coupled to the output of one different collection circuit and is capable of converting its input into a third number bit wide binary string selection code at its output. Each selection circuit is configured to receive from each selection code a bit from a bit position associated with that selection circuit. The enable circuit is configured to appropriately enable mapping of information from the PRMT to the ARMT.

  • Patent number: 8291200
    Abstract: A comparison circuit can reduce the amount of power consumed when searching a load queue or a store queue of a microprocessor. Some embodiments of the comparison circuit use a comparison unit that performs an initial comparison of addresses using a subset of the address bits. If the initial comparison results in a match, a second comparison unit can be enabled to compare another subset of the address bits.
