Reducing instruction miss penalties in applications
Embodiments include systems and methods for reducing instruction cache miss penalties during application execution. Application code is profiled to determine “hot” code regions likely to experience instruction cache miss penalties. The application code can be linearized into a set of traces that include the hot code regions. Embodiments traverse the traces in reverse, keeping track of instruction scheduling information, to determine where an accumulated instruction latency covered by the code blocks exceeds an amount of latency that can be covered by prefetching. Each time the accumulated latency exceeds the amount of latency that can be covered by prefetching, a prefetch instruction can be scheduled in the application code. Some embodiments insert additional prefetches, merge prefetches, and/or adjust placement of prefetches to account for scenarios, such as loops, merging or forking branches, edge confidence values, etc. |

Disappearing index for more efficient processing of a database query
A disappearing index allows faster processing of a database query without the startup time of a prior art sparse index. The disappearing index starts as a full index but is trimmed of index values that point to a row in the table that is not selected by the query. Thus the traditional index disappears as it becomes a sparse index tailored to the query. The query is able to execute faster using the now sparse index since the target database table is not accessed for duplicate values in the base table of the query. The query optimizer may determine to use a disappearing index based on estimates of the number of duplicate values in the base table. When the query is complete, the created disappearing table may be discarded or used for other queries that match the selection of the query that created the disappearing index. |

Face detection using division-generated Haar-like features for illumination invariance
Faces in images are quickly detected with minimal memory resource usage. Instead of calculating a Haar-like feature value by subtracting the average pixel intensity value in one rectangular region from the average pixel intensity value in another, adjacent rectangular region, a face-detection system calculates that Haar-like feature value by dividing the average pixel intensity value in one rectangular region by the average pixel intensity value in another adjacent rectangular region. Thus, each Haar-like value is calculated as a ratio of average pixel intensity values rather than as a difference between such average pixel intensity values. The feature values are calculated using this ratio-based technique both during the machine-learning procedure, in which the numerical ranges for features in known face-containing images are learned based on labeled training data, and during the classifier-applying procedure, in which an unlabeled image's feature values are calculated and compared to the previously machine-learned numerical ranges. |
