Abstract
Portions of a digital signal are buffered prior to being provided to a sub-system (e.g., a segmented DAC of a LDD) that is responsive to the digital signal. While being buffered, there is a determination, based on the buffered portions of the digital signal, of when one or more portions of the sub-system and/or another sub-system can be switched from a first state to a second state, where the second state results in less power dissipation than the first state. Additionally, or alternatively, while the portions of the digital signal are being buffered, there can be a determination, based on the buffered portions of the digital signal, of when one or more system related parameters can be adjusted to temporarily reduce power dissipation. Based on results of the determination(s), the state of one or more portions of the sub-system and/or another sub-system is/are selectively switched from the first state to the second state, or vice versa. Eventually, the portions of the digital signal are provided to the sub-system so that the sub-system can respond to the portions of the digital signal.
