A video processing device includes an input to receive pixel values for a set of pixels comprising a pixel window substantially centered around a select pixel that initially has a first pixel value. The video processing device further includes a first filter unit to determine a horizontal transient improvement value based on non-linear filtering of the pixel values in a horizontal direction, a second filter unit to determine a vertical transient improvement value based on non-linear filtering of the pixel values in a vertical direction, a third filter unit to determine a first diagonal transient improvement value based on non-linear filtering of the pixel values in a first diagonal direction, and a fourth filter unit to determine a second diagonal transient improvement value based on non-linear filtering of the pixel values in a second diagonal direction that is perpendicular to the first diagonal direction. The video processing device also includes an output to provide a second pixel value for the select pixel, the second pixel value based on the first pixel value, the vertical transient improvement value, the horizontal transient improvement value, the first diagonal transient improvement value, and the second diagonal transient improvement value.

A correlation module includes a plurality of first functional modules, a plurality of second functional modules, a plurality of function adjust modules, a summation module, a correlation value register, and a correlation evaluation module. The plurality of first functional modules is operably coupled to perform a first function upon a first corresponding pipelined data element to produce a first corresponding value. The plurality of second functional modules is operably coupled to perform a second function upon a second corresponding pipelined data element to produce a second corresponding value. The plurality of function adjust modules is operably coupled to selected ones of the plurality of first functional modules and to selected ones of the plurality of second functional modules. The summation module is operably coupled to sum the plurality of first corresponding values, the plurality of second corresponding values, and a previous correlation value to produce a current correlation value. The correlation evaluation module is operably coupled to compare the current correlation value with a correlation threshold to determine whether current pipelined data correlates with the expected pattern of the training sequence.

An interface implements a file system for supporting Java record and resource management between an operating system using a first programming language other than Java and a suite of Java applications. The interface provides a method for maintaining any number of files to be open in a manner transparent to the Java applications. Location information of a file is put in storage allocated for usage by Java code when a maximum number of open files is exceeded. A table is used to translate between file names of differing length and to identify directories in a manner to provide a hierarchical file system. An identifier is associated with a shortened Java file name in the table to quickly identify an operating system file with a shortened file name.
