20130339679 | METHOD AND APPARATUS FOR REDUCING AREA AND COMPLEXITY OF INSTRUCTION WAKEUP LOGIC IN A MULTI-STRAND OUT-OF-ORDER PROCESSOR - A computer system, a computer processor and a method executable on a computer processor involve placing each sequence of a plurality of sequences of computer instructions being scheduled for execution in the processor into a separate queue. The head instruction from each queue is stored into a first storage unit prior to determining whether the head instruction is ready for scheduling. For each instruction in the first storage unit that is determined to be ready, the instruction is moved from the first storage unit to a second storage unit. During a first processor cycle, each instruction in the first storage unit that is determined to be not ready is retained in the first storage unit, and the determining of whether the instruction is ready is repeated during the next processor cycle. Scheduling logic performs scheduling of instructions contained in the second storage unit. | 12-19-2013 |

20130007415 | METHOD AND APPARATUS FOR SCHEDULING OF INSTRUCTIONS IN A MULTI-STRAND OUT-OF-ORDER PROCESSOR - In accordance with embodiments disclosed herein, there are provided methods, systems, and apparatuses for scheduling instructions in a multi-strand out-of-order processor. For example, an apparatus for scheduling instructions in a multi-strand out-of-order processor includes an out-of-order instruction fetch unit to retrieve a plurality of interdependent instructions for execution from a multi-strand representation of a sequential program listing; an instruction scheduling unit to schedule the execution of the plurality of interdependent instructions based at least in part on operand synchronization bits encoded within each of the plurality of interdependent instructions; and a plurality of execution units to execute at least a subset of the plurality of interdependent instructions in parallel. | 01-03-2013 |
20140208074 | INSTRUCTION SCHEDULING FOR A MULTI-STRAND OUT-OF-ORDER PROCESSOR - In one embodiment, a multi-strand system with a pipeline includes a front-end unit, an instruction scheduling unit (ISU), and a back-end unit. The front-end unit performs an out-of-order fetch of interdependent instructions queued using a front-end buffer. The ISU dedicates two hardware entries per strand for checking operand-readiness of an instruction and for determining an execution port to which the instruction is dispatched. The back-end unit receives instructions dispatched from the hardware device and stores the instructions until they are executed. Other embodiments are described and claimed. | 07-24-2014 |

20090267621 | Method and device for rapid non-destructive quality control of powdered materials - Method and related device intended for rapid non-destructive testing of powdered materials with low electric conductivity such as cement and cement-based compositions through determination of their electrical properties. The invention involves an electromagnetic method, including an electronic circuit for generating an electric field in a capacitance probe that is inserted into the powder to be tested. Electrical properties of powdered materials are determined on the basis of a set of the values for a set of parameters including quality factor (Q-factor), capacitance, dissipation factor, and dielectric permeability of the material. These parameter values can be related to such characteristics as moisture content, particle size, and material composition. The method and device can indicate the differences between the samples with various quantities of unwanted components or reaction products, and the extent of sample ageing. | 10-29-2009 |
