Splits 4 bytes of each argument into 4 parts, each consisting of 1 byte. For corresponding parts functions performs substraction. Result is stored as unsigned int and returned.

__device__ ​ unsigned int __vsubss2 ( unsigned int  a, unsigned int  b )

Performs per-halfword (un)signed substraction, with signed saturation.

Returns

Returns computed value.

Description

__device__ ​ unsigned int __vsubss4 ( unsigned int  a, unsigned int  b )

Performs per-byte substraction with signed saturation.

Returns

Returns computed value.

__device__ ​ unsigned int __vsubus2 ( unsigned int  a, unsigned int  b )

Performs per-halfword substraction with unsigned saturation.

Returns

Returns computed value.
