Track error correction incorporating anti-aliasing
A method for correcting in-track position errors in a digital printing system includes determining a non-linear in-track position correction function responsive to measured in-track position errors, wherein the in-track position corrections are quantized to integer in-track position corrections. A representation of the in-track position correction function is stored in a digital memory, wherein the representation of the in-track position correction function includes the cross-track positions and transition direction of transitions in the in-track position correction function. Digital image data for a digital image to be printed is received, and corrected image lines are determined by resampling the digital image data responsive to the stored representation of the in-track position correction function. The corrected image lines are modified to provide anti-aliasing pixels at cross-track positions adjacent to transitions in the in-track position correction function. |

Processor that mitigates side channel attacks by expeditiously initiating flushing of instructions dependent upon a load instruction that causes a need for an architectural exception
A superscalar out-of-order speculative execution microprocessor mitigates side channel attacks that attempt to exploit speculation windows within which instructions dependent in their execution upon a result of a load instruction may speculatively execute before being flushed because the load instruction raises an architectural exception.

Each data row is associated with a respective join key value. From multiple buckets of a hash table, a bucket is selected that contains entries of multiple respective join key values in respective locations within the bucket. Whether or not the bucket contains an entry of the join key value of a build data row is detected. While building, multiple locations within the bucket are concurrently inspected to find an empty location in which to store the entry of the join key value of the build data row. The bucket is concurrently probed to detect whether or not the entries in the bucket include an entry of a join key value of a probe data row. For the join request, a response is sent that is based on the concurrent probing of the bucket. |
