Ultra Direct Memory Access (UDMA) is just an advanced, updated version of Direct Memory Access. It introduced features such as double transition clocking (similar to DDR used with memory) and CRC checks.
DMA offered speeds up to 16.7 MB/s whereas UDMA offered speeds up to 133 MB/s per channel (UDMA Mode 6).

DMA (Direct Memory Access) allows devices to transfer data directly to and from memory without involving the CPU. UDMA (Ultra DMA) is an improvement over DMA that increases data transfer speeds by using faster transfer modes and protocols.
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
The formula for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
The difference between 164 and 220 is 56.
To calculate the phase difference between two waves, you can measure the difference in their starting points or peaks. This difference is usually expressed in degrees or radians.
