20080276062 | MEMORY MANAGEMENT FOR A MOBILE MULTIMEDIA PROCESSOR - Certain embodiments of the invention may be found in a method for memory management for a mobile multimedia processor. The method may comprise receiving within a mobile multimedia processor chip a plurality of memory requests. The plurality of memory requests may be handled by allocating memory from at least one on-chip memory block and/or at least one off-chip memory block. The memory may be allocated based on a priority level of each of the plurality of memory requests and at least one dynamically settable global memory allocation priority threshold. A new dynamically settable memory allocation priority threshold may be dynamically determined based on a new application and/or by monitoring at least one software process in at least one present application. Additionally, new memory request priority level may be dynamically determined for each memory request in at least one software process in a new application. | 11-06-2008 |
20110010519 | MEMORY MANAGEMENT FOR A MOBILE MULTIMEDIA PROCESSOR - Certain embodiments of the invention may be found in a method for memory management for a mobile multimedia processor. The method may comprise receiving within a mobile multimedia processor chip a plurality of memory requests, and setting a priority level for each of the plurality of received memory requests. Memory from one or both of at least one on-chip memory block and at least one off-chip memory block may be allocated, and one or more of the plurality of received memory requests may be handled, using the allocated memory, based on a corresponding set priority level and at least one dynamically settable memory allocation priority threshold. The priority level may be set based on an expected number of memory accesses and/or a total number of memory accesses per unit time. The off-chip memory block may be placed into a power-saving mode. | 01-13-2011 |

20120200354 | APPARATUS AND METHODS FOR ENVELOPE TRACKING CALIBRATION - Apparatus and methods for envelope tracking calibration are provided. In one embodiment, a method of calibrating an envelope tracker having an envelope shaping table generated at a desired gain compression of a power amplifier is provided. The method includes generating a supply voltage for the power amplifier using the envelope tracker, operating the supply voltage of the power amplifier at a first voltage level associated with substantially no gain compression of the power amplifier, and measuring an output power of the power amplifier at the first voltage level. The method further includes decreasing a voltage level of the supply voltage one or more times and measuring the output power at each voltage level, determining a second voltage level of the power amplifier associated with a gain compression equal to about that of the desired gain compression, and calibrating the envelope tracker based on the determination. | 08-09-2012 |

20160099742 | APPARATUS AND METHODS FOR CALIBRATION OF ENVELOPE TRACKERS - Apparatus and methods for calibration of envelope trackers are provided. In one embodiment, a power amplifier system includes a VGA that amplifies an RF input signal to generate an amplified RF input signal, a power amplifier that amplifies the amplified RF input signal to generate an RF output signal, and an envelope tracker that generates a supply voltage for the power amplifier. The envelope tracker includes a scaling module that generates a scaled envelope signal based on a power control level (PCL) signal and an envelope signal that changes in relation to an envelope of the RF input signal. The envelope tracker further includes a calibration module that controls an amount of scaling of the scaled envelope signal based on calibration data to compensate for an envelope amplitude misalignment of the envelope tracker. The envelope tracker controls the voltage level of the supply voltage based on the scaled envelope signal. | 04-07-2016 |

20150155834 | APPARATUS AND METHODS FOR CALIBRATING ENVELOPE TRACKERS - Apparatus and methods for envelope tracking calibration are provided. In one embodiment, a power amplifier system includes a power amplifier, an envelope tracker that generates the power amplifier's supply voltage, a power detector, and a calibration module. The envelope tracker includes an envelope shaping table generated at a desired gain compression and a scaling module that scales an amplitude of an envelope signal. The power detector measures the power amplifier's output power, and the calibration module provides calibration data to the scaling module to change the scaling of the envelope signal's amplitude. The calibration module sets the calibration data to a first value corresponding to a supply voltage level associated with substantially no gain compression, and reduces the supply voltage level by changing the calibration data until the power detector indicates that the gain compression of the power amplifier is about equal to the desired gain compression. | 06-04-2015 |
