Bit Rotate

Rotate input signal by bit positions

Library

HDL Coder / Logic and Bit Operations

Description

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

Parameters

Rotate Mode: Specifies direction of rotation, left or right. The default is Rotate Left.

Rotate Length: Specifies the number of bits to rotate. Specify a value greater than or equal to zero. The default is 0.

Ports

The block has the following ports:

Input

Supported data types: Fixed-point, integer (signed or unsigned), Boolean
Minimum bit width: 2
Maximum bit width: 128

Output

Has the same data type as the input signal.

Extended Capabilities

C/C++ Code Generation
Generate C and C++ code using Simulink® Coder™.

HDL Code Generation
Generate Verilog and VHDL code for FPGA and ASIC designs using HDL Coder™.

HDL Coder™ provides additional configuration options that affect HDL implementation and synthesized logic.

HDL Architecture

This block has a single, default HDL architecture.

HDL Block Properties

General
ConstrainedOutputPipeline	Number of registers to place at the outputs by moving existing delays within your design. Distributed pipelining does not redistribute these registers. The default is `0`. For more details, see ConstrainedOutputPipeline.
InputPipeline	Number of input pipeline stages to insert in the generated code. Distributed pipelining and constrained output pipelining can move these registers. The default is `0`. For more details, see InputPipeline.
OutputPipeline	Number of output pipeline stages to insert in the generated code. Distributed pipelining and constrained output pipelining can move these registers. The default is `0`. For more details, see OutputPipeline.
