20120144471UPDATING STORED PASSWORDS - A device may include an authentication server and a server. The authentication server may receive a first form of a password from a client in accordance with an authentication protocol, and authenticate the client based on a comparison of the first form to a value derived from a second form of the password stored in a password database. The comparison fails when the first form is not comparable to a value derived from the second form. The server may establish a secure connection to the client, receive a plain-text password from the client over the secure connection, authenticate the client by comparing a value derived from the plain-text password with a value derived from the second form, and update the password database with a third form of the password that permits the authentication server to successfully authenticate the client when the authentication server receives the first form.06-07-2012

20090010252Integrated Memory for Storing Egressing Packet Data, Replay Data and To-be Egressed Data - An integrated egress/replay memory structure is provided with split rate write and read ports and means for managing at least three types of data moving into, through and/or out of the integrated memory structure, namely: (1) currently egressing packet data; (2) replay data; and (3) to-be egressed data. Additionally, a shared free space (4) is managed between the storage areas of the (2) replay data and (3) the to-be egressed data. The to-be egressed data (PdBx) is allowed to enter into (to be written into) a front-end raceway portion of the integrated memory structure at a rate which can be substantially greater than that allowed for corresponding egressing packet data (PdUx). Thus, even when egressing packet data that is ahead in line is shifting out toward a slow rate egress port, this slowing factor does not slow the speed at which the to-be egressed data (PdBx) can be shifted into the front-end raceway portion. A shared free space memory area is maintained between the storage areas of the replay data (PdAx) and to-be-egressed data (PdBx). When a positive acknowledgement (ACK) is received from the destination of already-egressed data (of the After-Transmission Data, or PdAx), the corresponding replay storage area (the area storing the acknowledged PdAx data) can be reallocated for use as an empty part of the raceway portion.01-08-2009

20100166073Multiple-Candidate Motion Estimation With Advanced Spatial Filtering of Differential Motion Vectors - Embodiments include a motion estimation method performed in a parallel processing system that determines a list of several candidate motion vectors for a macroblock of a video image and retains them through multiple computation passes. All candidate motion vectors are used as potential neighboring predictors, so that the best combination of differential vectors rises to the top of the candidate list. Numerous combinations of differential motion vectors are considered during the process that compares motion vectors among up to eight neighboring macroblocks, instead of simply between pairs of macroblocks. The motion estimation system is configured to use a large number of compute engines, such as on a highly parallel GPU platform. This is achieved by having no dependencies between macroblocks except one per pass. This allows the number of calculations per pass to be very large.07-01-2010
