Abstract
A method for performing phase aware dynamic scheduling of a plurality of double data rate (DDR) commands includes determining a ratio of a frequency of DDR controller clock to a frequency of a DDR clock. The method includes determining a number of clock cycles of the DDR clock required for each DDR command of the plurality of DDR commands. The method includes, based on the ratio of the frequency of the DDR controller clock to the frequency of the DDR clock and the number of clock cycles of the DDR clock required for each DDR command, determining a sequence of the plurality of DDR commands according to a priority corresponding to the each DDR command, and transmitting the plurality of DDR commands to DDR devices over one or more clock cycles of the DDR controller clock according to the determined sequence of the plurality of DDR commands.
