General Multiplexed Deinterleaver

Restore ordering of symbols using specified-delay shift registers (HDL Coder)

Description

The General Multiplexed Deinterleaver block is available with Communications System Toolbox™.

For information about the simulation behavior and block parameters, see General Multiplexed Deinterleaver.

HDL Architecture

The implementation for the General Multiplexed Deinterleaver block is shift register based. If you want to suppress generation of reset logic, set the implementation parameter ResetType tonone.

When you set ResetType to none, reset is not applied to the shift registers. When registers are not fully loaded, mismatches between Simulink® and the generated code occur for some number of samples during the initial phase. To avoid spurious test bench errors, determine the number of samples required to fill the shift registers. Set the Ignore output data checking (number of samples) option accordingly. (If you are using the command-line interface, you can use the IgnoreDataChecking property for this purpose.)

HDL Block Properties

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. See also 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. See also 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. See also OutputPipeline.

ResetType

Suppress reset logic generation. The default is default, which generates reset logic. See also ResetType.
