Abstract
A method for increasing a resolution by N bits performed by a processing circuit of a motor driving system, where N is a positive integer, and the method includes: performing a conversion upon an analog command, to generate a command count value; performing a first N-bit right-shifting operation upon the command count value, to generate an initial output value; performing a logical operation upon the command count value, to generate a low bit value; generating an overflow value according to the low bit value; and determining a final output value according to the initial output value and the overflow value.
