Patent number: 9785211Abstract: The feature size of semiconductor devices continues to decrease in each new generation. Smaller channel lengths lead to increased leakage currents. To reduce leakage current, some power domains within a device may be powered off (e.g., power collapsed) during periods of inactivity. However, when power is returned to the collapsed domains, circuitry in other power domains may experience significant processing overhead associated with reconfiguring communication channels to the newly powered domains. Provided in the present disclosure are exemplary techniques for isolating power domains to promote flexible power collapse while better managing the processing overhead associated with reestablishing data connections.Type: GrantFiled: February 13, 2015Date of Patent: October 10, 2017Assignee: QUALCOMM IncorporatedInventors: Christopher Edward Koob, Xufeng Chen, Robert Allan Lester, Manojkumar Pyla, Peixin Zhong

Publication number: 20140266103Abstract: 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.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: QUALCOMM INCORPORATEDInventors: Yuhe Wang, Marzio Pedrali-Noy, Xuhao Huang, Martin Saint-Laurent, Xufeng Chen

Patent number: 8533530Abstract: 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. Trusted and untrusted debugging operational control occurs in operating a core processor associated with the digital signal processor. A debugging process within a debugging mechanism associates with the core processor. The core processor process determines the origin of debugging control as trusted debugging control or untrusted debugging control. In the event of trusted debugging control, the core processor process provides to the trusted debugging control a first set of features and privileges. Alternatively, in the event that debugging control is untrusted debugging control, the core processor process provides the untrusted debugging control a second restricted set of features and privileges, all for maintaining security and proper operation of the core processor process.Type: GrantFiled: November 15, 2006Date of Patent: September 10, 2013Assignee: QUALCOMM IncorporatedInventors: Lucian Codrescu, William C.

Patent number: 8484516Abstract: 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.Type: GrantFiled: April 11, 2007Date of Patent: July 9, 2013Assignee: QUALCOMM IncorporatedInventors: Louis Achille Giannini, William Anderson, Xufeng Chen

Patent number: 8380966Abstract: 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. Stuffing instructions in a processing pipeline of a multi-threaded digital signal processor provides for operating a core processor process and a debugging process within a debugging mechanism. Writing a stuff instruction into a debugging process registry and a stuff command in a debugging process command register provides for identifying a predetermined thread of the multi-threaded digital signal processor in which to execute the stuff instruction. The instruction stuffing process issues a debugging process control resume command during a predetermined stage of executing on the predetermined thread and directs the core processor to perform the stuff instruction during the debugging process. The core processor may then execute the stuffed instruction in association with the core processor process and the debugging process.Type: GrantFiled: November 15, 2006Date of Patent: February 19, 2013Assignee: QUALCOMM IncorporatedInventors: Lucian Codrescu, William C.
