Bit Rotate

Shifts the input signal by bit positions.

blockType: Bit Rotate

bit rotate

Path in the library:

/Basic/Logic and Bit Operations/Bit Rotate

Description

The Bit Rotate block shifts the input signal left or right by the specified number of bit positions.

Ports

Input

# IN_1 — input signal
scalar | vector

Details

An input signal that is shifted:

  • Minimum bit width: 2.

  • Maximum bit width: 128.

Data types

Int8, Int16, Int32, Int64, Int128, UInt128 UInt8, UInt16, UInt32, UInt64, Bool, Fixed.
Complex numbers support

Yes

Output

# OUT_1 — output signal
scalar | vector

Details

An output signal shifted by a specified number of bits. The output signal has the same data type as the input signal.

Data types

Int8, Int16, Int32, Int64, Int128, UInt128, UInt8, UInt16, UInt32, UInt64, Bool, Fixed.
