Byte Reversal/Change Endianess

Reverse little-endian data for big-endian processor

Library:
Simulink Real-Time / Utilities

Description

You use the Byte Reversal/Change Endianess block for 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.

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.

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.
