    • Various embodiments of the present invention provide systems and methods for data processing. As an example, a data processing circuit is discussed that includes: a data detector circuit, a data decoder circuit, and a power monitor circuit. The data detector circuit is operable to apply a data detection algorithm to a data input and a decoded output to yield a detected output. The data decoder circuit is operable to apply a data decoding algorithm to the detected output to yield the decoded output. The power monitor circuit is operable to receive a first power status signal from the data detector circuit and a second power status from the data decoder circuit, and to calculate a power usage of a combination of at least the data detector circuit and the data decoder circuit. In such a system, a number of global iterations through a combination of the data decoder circuit and the data detector circuit is variable and both of the first power status signal and the second power status signal varies at least in part as a function of the number of global iterations.
