DIVS – Signed divide
Architecture revision:
Architecture revision1 and higher.
Description
Performs a signed divide between the two 32-bit register specified. The quotient is returned in
Rd, the remainder in Rd+1. No exceptions are taken if dividing by 0. Result in Rd and Rd+1 is
UNDEFINED when dividing by 0. The sign of the remainder will be the same as the dividend,
and the quotient will be negative if the signs of Rx and Ry are opposite.
