Byte Reversal/Change Endianess

Reverse little-endian data for big-endian processor

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. The following is the Change Endianess block.

Examples

Simple ASCII Encoding/Decoding Loopback Test (with Baseboard Blocks)

Convert a single floating point number to ASCII and transmit the value over a serial link.

ASCII Encoding/Decoding Loopback Test (with Baseboard Blocks)

Send ASCII data over a serial link.

• Open Model

ASCII Encoding/Decoding Resync Loopback Test

Use the ability of the FIFO Read HDRS block to resynchronize after being repeatedly disabled and apply this ability to resolve errors such as when a message is only partially complete at the time the read is attempted.

Parameters

Block Parameters for Change Endianess

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:  />

Byte Reversal Block Parameters

Number of inputs — Number of ports
