Abstract
A power-saving method and circuit in a data processing device comprising a data buffer. Data transfer commands associated with a data source and a data destination are received at the data processing device. The data transfer commands are accumulated until an amount of data associated with the read commands is greater than a predefined threshold. When the amount of data is less than the predefined threshold and the data buffer is empty, the data buffer is signaled to enter or to maintain a power saving mode. When the amount of data is at least the predefined threshold, the data buffer is signaled to exit the power saving mode following a predetermined delay. Processing of the commands and data in respective pipelines is monitored to time exiting of the buffer from the power saving mode for arrival of the data. Power saving mode use and thus power saving are optimized.
