20150309097 | SYSTEMS AND METHODS FOR JOINT ANGLE-FREQUENCY DETERMINATION - A system for data acquisition and processing includes a selector for obtaining samples from one or more sensors, each of which is configured to collect a sample during one or more sampling intervals forming a dwell period. The selector is configured to obtain only a subset of samples of a complete set of samples that can be collected during a dwell period. A solver is configured to solve an underdetermined system based on the collected samples and a mapping relation/phase function, to jointly determine one or more angles and one or more frequencies of transmissions received by the one or more sensors. | 10-29-2015 |
20150309778 | SYSTEMS AND METHODS FOR APPROXIMATION BASED OPTIMIZATION OF DATA PROCESSORS - A compilation system can apply a smoothness constraint to the arguments of a compute-bound function invoked in a software program, to ensure that the value(s) of one or more function arguments are within specified respective threshold(s) from selected nominal value(s). If the constraint is satisfied, the function invocation is replaced with an approximation thereof. The smoothness constraint may be determined for a range of value(s) of function argument(s) so as to determine a neighborhood within which the function can be replaced with an approximation thereof. The replacement of the function with an approximation thereof can facilitate simultaneous optimization of computation accuracy, performance, and energy/power consumption. | 10-29-2015 |
20150309779 | SYSTEMS AND METHODS FOR POWER OPTIMIZATION OF PROCESSORS - A compilation system generates one or more energy windows in a program to be executed on a data processors such that power/energy consumption of the data processor can be adjusted in which window, so as to minimize the overall power/energy consumption of the data processor during the execution of the program. The size(s) of the energy window(s) and/or power option(s) in each window can be determined according to one or more parameters of the data processor and/or one or more characteristics of the energy window(s). | 10-29-2015 |
