ushr (sm4 - asm)

Shift right.

ushr dest[.mask], src0[.swizzle], src1.select_component
Item Description
[in] The address of the result of the operation.
[in] The components to shift.
[in] The amount to shift src0.


This instruction performs a component-wise shift of each 32-bit value in src0 right by an unsigned integer bit count provided by the LSB 5 bits (0-31 range) in src1.select_component, inserting 0. The 32-bit per component result is placed in dest. The count is a scalar value applied to all components.

This instruction applies to the following shader stages:
