WebI didn't see an unsigned saturation instruction for 32bit integers, only for packed16 UQUADD16 and packed8. There's a 32bit add with signed-saturation, though. Also, unfortunately this C code compiles to horrible code for the 32bit case: all the overhead of … WebSigned overflow occurs when the result of addition is too large for a given type to represent. This occurs when either: Addition of two positive integers result in a negative integer result (so the result msb - the sign bit - is 1 when it should be zero); or. Addition of two negative integers result in a positive integer result (so the result msb is 0 when it should be 1).

Typically, general-purpose microprocessors do not implement integer arithmetic operations using saturation arithmetic; instead, they use the easier-to-implement modular arithmetic, in which values exceeding the maximum value "wrap around" to the minimum value, like the hours on a clock passing from 12 to 1. In hardware, modular arithmetic with a minimum of zero and a maximum of r − 1, where r is the radix can be implemented by simply discarding all but the lowes… WebConverts 4 signed word integers from mm and 4 signed word integers from mm/m64 into 8 unsigned byte integers in mm using unsigned saturation. 66 0F 67 /r PACKUSWB xmm1, …
