WebApr 10, 2024 · Solution 1. If you just want to divide an integer value in r0 by 9 you can approximate that with: ldr r3, =0x1C71C71D # 1 C71C71D == ( 2 ^ 32 / 9) + 1 umull r9, r3, r0, r3. r3 now contains the integer part of the quotient, and r9 contains the fractional part scaled by 2^32. To get the remainder you'd just multiply the integer part of the ... WebUDIV. Unsigned Divide divides a 32-bit unsigned integer register value by a 32-bit unsigned integer register value, and writes the result to the destination register. The condition flags are not affected.
