Operator ShiftRight

Operator Library: Arithmetics

The operator performs an arithmetic shift of the input data to the right. The number of bits to be shifted is defined using parameter Shift. Each bit at the input is right shifted by the parameterized number of bits.

Bit shifting is usually used to scale a value by a power of two value. For example a right shift by one bit will divide the input value by 2. A right shift by 2 bits will divide the input value by 4.

Each color component is shifted separately.

Property Value
Operator Type O
Input Link I, data input
Output Link O, data output

Supported Link Format

Link Parameter Input Link I Output Link O
Bit Width [1, 64] unsigned, [2, 64] signed auto1
Arithmetic {unsigned, signed} as I
Parallelism any as I
Kernel Columns any as I

The bit width at the output is the input bit width minus the value of parameter Shift.


Type static parameter
Default 0

[0, Input BitWidth - 1] for unsigned

[0, Input BitWidth - 2] for signed

This parameter defines the number of bits by which the input is right shifted.
