摘要： In one implementation, a device may include a voltage regulator circuit, a data processing circuit, and an error correction circuit, where the error correction circuit may correct errors in data processed by the data processing circuit to obtain error-corrected data and output an error-corrected version of the processed data. Additionally, an error monitor circuit may output an error signal indicative of a level of the errors in the processed data. A control circuit may receive the error signal and control the voltage regulator circuit to adjust, based on the error signal, the supply voltage to the data processing circuit. In some implementations, the control circuit may also base its decision to control the voltage regulator circuit based on available timing margins in the data processing circuit.

摘要： A system, method, and apparatus is disclosed for interpolation of an output of an analog to digital converter (ADC) to enable operation of the ADC at a sampling rate that is independent of the sampling rate for a DSP core so as to efficiently enable operation at higher date rates. According to one of the embodiments, an interpolation circuit is coupled between the ADC and DSP core and receives a first plurality of samples of data at the first data rate from the ADC and supplies a plurality of samples of second data at a second data rate to the DSP core; the second data rate being less than the first data rate. According to one of the embodiments, the interpolation circuit includes a memory and a FIR filter circuit having filter tap coefficient values selected to provide attenuation at high frequencies to reduce aliasing noise.
