Disclosed are systems and methods of dynamic remote peripheral binding. In one embodiment, such a system includes a local system () configured to bind a smart card reader () to the local system (). The smart card reader () is configured to extract data from a smart card (). The system includes a local authentication engine () that prompts the user for user authentication information associated with the smart card (). The local authentication engine () authenticates that the user is associated with the smart card (), is authorized to access the user credentials and extracts them from the smart card (). A remote access client () module establishes a remote session () from the local system () to a remote system (). The local system () unbinds the smart card reader () from the local system () and binds the smart card reader () to the remote system ().

Dynamic remote peripheral binding

A technique for performing clear operations in a region having a subregion. Responsive to a first clear command: perform an initialization in which stale information is eliminated from pixels outside the subregion. Responsive to subsequent clear commands: update a current clear count for the region; and write the updated current clear count into clear count values associated with pixels outside the subregion. Prior to creating the subregion, a conventional fast clear technique may be employed in the region. After creating the subregion and during its life, the inventive technique may be employed. After the subregion is discontinued, the conventional technique may once again be employed. The inventive technique may be employed optionally depending on the percentage of the region's area occupied by the subregion.

Fast clear technique for display regions having subregions

A technique for performing clear operations in a region having a subregion. Responsive to a clear command: a current clear count for the region is left unchanged; a predetermined value is written into the pixels of the subregion; and the current clear count is written into pixel clear counts of the subregion. Prior to creating the subregion, clear commands may be handled according to a conventional fast clear technique. After creating the subregion and during the life of the subregion, clear commands may be handled according to the inventive technique. After the subregion is discontinued, clear commands may once again be handled according to the conventional technique. The inventive technique may be employed optionally depending on the percentage of the region's area occupied by the subregion.

A technique for filling a memory area that represents a rectangle. The rectangle or a first section thereof may be divided into i&plus;j horizontal subsections. The i horizontal subsections may be filled in a first pass using i region fill processors. And the j horizontal subsections may be filled in a second pass using j region fill processors. A second section of the rectangle may be filled by dividing the second section into n vertical subsections having equal width and filling the n vertical subsections using n region fill processors.
