20080256396 | INTER-THREAD TRACE ALIGNMENT METHOD AND SYSTEM FOR A MULTI-THREADED PROCESSOR - Techniques for the design and use of a digital signal processor, including (but not limited to) for processing transmissions in a communications (e.g., CDMA) system. Inter-thread trace alignment with execution trace processing includes recording timing data relating to a common predetermined event. Such an event may be the number of cycles since a last thread initiated execution tracing or the number of cycles since all threads terminated execution tracing. The number of cycles at which a thread initiates execution tracing is referenced to the common predetermined event for maintaining the timing of execution tracing. The data relating to the common predetermined event is then updated to associate with the time at which the thread initiated execution tracing. The result is to permit aligning the timing data associated with all threads. Interrelated records permit reconstructing interdependent execution tracing information for threads operating in the multi-threaded processor, as well as synchronizing timing data for all operating threads. | 10-16-2008 |

20140266103 | DIGITALLY ASSISTED REGULATION FOR AN INTEGRATED CAPLESS LOW-DROPOUT (LDO) VOLTAGE REGULATOR - Techniques are described that embed a digital assisted regulator with an LDO regulator on a chip without requiring a capacitor external to the chip and to regulate a voltage without undershoot. The digital assisted regulator responds to information regarding operation of the LDO regulator and to a signal that provides advance notification of a load change. When the advance notification signal is received, the digital assisted regulator pulls a circuit's supply voltage up to a chip's incoming supply voltage. When the correct operating voltage has been reached and any undershoot problem removed, the digital assisted regulator balances the current it provides with the current provided by the LDO regulator, to allow a quick response time for other load changes. Also, bandwidth of an LDO regulator may be expanded by use of an advance notice signal to increase bias current of an LDO output device to meet an upcoming load change. | 09-18-2014 |
