Problems solved by technology

Known DCVS functionality does not Has a sufficiently fast response or processing time for changing the frequency and / or voltage of the CPU to adequately process the data and thus satisfy the needs of all clients of the modem
In some scenarios, using DCVS may result in lower DC current consumption state and slower transient response
In these cases, conventional DCVS results in processing response times that cannot meet the needs of all processor clients

Embodiment Construction

[0019] The methods and apparatus disclosed in this application provide a mechanism for data services to shorten the response time of control algorithms such as DCVS, thereby maintaining the data throughput performance of the CPU or processor. In a particular aspect, the present invention presents methods and apparatus for setting or modifying the minimum CPU level of a DCVS to accommodate data movement requirements running on high priority tasks. An interface or similar module between the DCVS and its clients may be provided in order to vary the DCVS response time or DCVS sensitivity. As part of the method, receiver (Rx), transmit (Tx) or other data buffers are monitored. If any buffer is filled above the first predetermined threshold, the data service may call the DCVS Application Programming Interface (API) to shorten the response time, which results in an increase in CPU clock frequency. In another aspect, the data service may restore the DCVS response time to a default va...

Abstract

Apparatus and methods are disclosed for power optimization in a wireless device. The apparatus and methods effect monitoring the amount of data stored in a data buffer that buffers data input to and data output from a processor. Dependent on the amount of data stored in the buffers parameters of a control function, such as a Dynamic Clock and Voltage Scaling (DCVS) function are modified based on the amount of data stored in the data buffer. By modifying or pre-empting the parameters of the control function, which controls at least processor frequency, the processor can process applications more dynamically over default parameter settings, especially in situations where one or more real-time activities having strict time constraints for completion are being handled by the processor as evinced by increased buffer depth. As a result, power usage is further optimized as the control function is more responsive to processing conditions.

Description

[0001] priority claim [0002] This patent application claims priority to Provisional Application No. 61 / 245,477, filed September 24, 2009, entitled "PRE-EMPTING DYNAMIC CLOCK AND VOLTAGE SCALING (DCVS) RESPONSE TIME," which is assigned to this application assignee, which is hereby expressly incorporated by reference. technical field [0003] In general terms, the present invention relates to apparatus and methods for optimizing power consumption of electronic components (eg, wireless devices). In particular, the present invention relates to methods and apparatus for optimizing power consumption by improving circuit response time of electronic components using Dynamic Clock and Voltage Scaling (DCVS) techniques. Background technique [0004] Optimizing the power consumption of electronic devices is becoming increasingly important, especially for devices such as battery-operated mobile devices. For user convenience, it is desirable to extend battery operating time as much a...
