Abstract: Techniques for synchronizing error concealment during video decoding include determining a decoding error. A recovery point within a current frame is determined for each decoding error. The determined recovery point may be the start of the next good slice of a frame after the current frame containing the error. The number of macroblock to be concealed is also determined. The determined number of macroblocks from the recovery point may then be concealed in hardware or software. The techniques for concealing errors may also include determining available macroblocks for use in concealing the error. The techniques for concealing errors may further include selecting a given concealment mode.

Abstract: Efficient and effective permission confidential information protection systems and methods are described. The secure information protection systems and methods facilitate storage of confidential information in a manner safe from rogue software access. In one embodiment, a confidential information protection method is implemented in hardware and facilitates protection against software and/or Operating System hacks. In one exemplary implementation, a confidential information protection method includes setting a permission sticky bit flag to a default state upon system set up. The permission sticky bit flag access permission indication is adjusted at system reset in accordance with an initial application instruction. Access to the confidential information is restricted in accordance with the permission sticky bit and the permission sticky bit is protected from adjustments attempting to violate the permission indication.

Abstract: A clock module is coupled in parallel to a number of data processing modules that are coupled in series. The data processing modules can be individually clock-gated. Each of the data processing modules can determine whether or not it can be placed into an idle state. To reduce power consumption, any subset of the data processing modules that are eligible to be placed in an idle state can be clock-gated. The remaining data processing modules can continue to receive clock signals from the clock module and thus can continue to process data.
