Abstract
A method for generating a reflection of data in a plurality of processing elements comprises shifting the data along, for example, each row in the array until each processing element in the row has received all the data held by every other processing element in that row. Each processing element stores and outputs final data as a function of its position in the row. A similar reflection along a horizontal line can be achieved by shifting data along columns instead of rows. Also disclosed is a method for reflecting data in a matrix of processing elements about a vertical line comprising shifting data between processing elements arranged in rows. An initial count is set in each processing element according to the expression (2×Col_Index) MOD (array size). In one embodiment, a counter counts down from the initial count in each processing element as a function of the number of shifts that have peen performed. Output is selected as a function of the current count. A similar reflection about a horizontal line can be achieved by shifting data between processing elements arranged in columns and setting the initial count according to the expression (2×Row_Index) MOD (array size). The present invention represents an efficient method for obtaining the reflection of data.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
