DETERMINING PHYSICAL ADDRESSES OF MEMORY DEVICES USING DIVISION BY PRIME NUMBERS

Abstract: a processing unit, associated with a host device, adapted to receive a request to calculate a first physical address of an external device based on a second physical address of the host device; determine a tree of parallel adders corresponding to the division operation; obtain an output value from the tree of parallel adders based on the input values; and calculate the first physical address using the output value. the first physical address of the external device is to be calculated based on a division operation that divides the second physical address by a divisor. the tree of parallel adders is determined based on input values that include a number of bits of the second physical address and a divisor.
