<p>Apparatus and methods of determining a modulo count of a synchronization number in a sleep capable system. The synchronization number is stored in a comparison register, and a comparison number equal to the largest power of two multiple of the modulus within a predetermined range is subtracted from the synchronization number. If the difference is zero, the difference is stored in the comparison register, replacing the previous number stored in the register. If the difference is less than zero, the number stored in the register remains unchanged. The comparison number is right shifted, resulting in division by two. The process is repeated for a number of loops equal to the power of two, or until the difference is less than the modulus.</p> |
