  • Patent number: 9785211
    Abstract: 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.

  • Patent number: 8972642
    Abstract: Systems and method for reducing interrupt latency time in a multi-threaded processor. A first interrupt controller is coupled to the multi-threaded processor. A second interrupt controller is configured to communicate a first interrupt and a first vector identifier to the first interrupt controller, wherein the first interrupt controller is configured to process the first interrupt and the first vector identifier and send the processed interrupt to a thread in the multi-threaded processor. Logic is configured to determine when the multi-threaded processor is ready to receive a second interrupt. A dedicated line is used to communicate an indication to the second interrupt controller that the multi-threaded processor is ready to receive the second interrupt.

  • Publication number: 20140266103
    Abstract: 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.

  • Patent number: 8594658
    Abstract: The present invention relates to a method and an apparatus for diagnosing a feeder misconnection. The method includes: for each planned non-co-site strong neighboring cell of a sector to be analyzed, by using each sector of a base station where the sector to be analyzed is located as an interference source, determining a sector having the greatest interference with the non-co-site strong neighboring cell; and when in the planned non-co-site strong neighboring cells of the sector to be analyzed, the sector having the greatest interference with the non-co-site strong neighboring cell is in another sector except the sector to be analyzed, and a ratio of the number of non-co-site strong neighboring cells of the another sector to the total number of the non-co-site strong neighboring cells reaches a preset first threshold, determining that a feeder of the sector to be analyzed is misconnected.

  • Patent number: 8533530
    Abstract: 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.

  • Patent number: 8484516
    Abstract: 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.

  • Patent number: 8380966
    Abstract: 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.

  • Patent number: 8370806
    Abstract: A method and system provide processing instructions in a multi-threaded process including the use of breakpoint instructions for generating debugging event(s). A debugging event is generated in response to the execution of breakpoint instructions and executes debugging instructions in response to the debugging event. The debugging instructions debug processing instructions in the multi-threaded processor by transitioning at least one or more threads into a debugging mode. A debugging return is generated for reporting the executing debugging instructions in the subset of the threads of the multi-threaded processor.
