Byte Reversal/Change Endianess

R2026b

Reverse little-endian data for big-endian processor

• 

Byte Reversal/Change Endianess block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink Real-Time / Utilities

Description

The Byte Reversal/Change Endianess block provides communication between a Simulink^® Real-Time™ system and a system running with a processor that is big-endian. Processors compatible with the Intel^® 80x86 family are little-endian. For this situation, insert a Byte Reversal/Change Endianess block before the Pack block and another just after the Unpack block.

Parameters

Change Endianess Block Parameters

Number of input ports — Number of ports

1 (default)

The number of input ports adjusts to follow this parameter and the number of outputs is equal to the number of inputs.

Programmatic Use

Block Parameter: numInp

Machine word length — Word length for conversion

Byte (default) | Word | Double Word

Select a machine word length from the list to which to convert the data.

Programmatic Use

Block Parameter: lengthIn

Byte Reversal Block Parameters

Number of inputs — Number of ports

1 (default)

Programmatic Use

Block Parameter: numInp

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
