Largest atomic size: integer

Description

Specify the largest integer data type that can be atomically loaded and stored on the hardware that you use to test code.

Category: Hardware Implementation

Settings

Default: Char

Char: Specifies that char is the largest integer data type that can be atomically loaded and stored on the hardware that you use to test code.
Short: Specifies that short is the largest integer data type that can be atomically loaded and stored on the hardware that you use to test code.
Int: Specifies that int is the largest integer data type that can be atomically loaded and stored on the hardware that you use to test code.
Long: Specifies that long is the largest integer data type that can be atomically loaded and stored on the hardware that you use to test code.
LongLong: Specifies that long long is the largest integer data type that can be atomically loaded and stored on the hardware that you use to test code.

Tip

Use this parameter, where possible, to remove unnecessary double-buffering or unnecessary semaphore protection, based on data size, in generated multirate code.

Dependencies

Selecting a device by using the Device vendor and Device type parameters sets a device-specific value for this parameter.
This parameter is enabled only if you can modify it for the selected hardware.
You can set this parameter to LongLong only if the hardware used to test the code supports the C long long data type and you have selected Enable long long.

Recommended Settings

Application	Setting
Debugging	No impact
Traceability	No impact
Efficiency	Target specific
Safety precaution	No impact when Test hardware is the same as production hardware is selected. If it is not selected, no recommendation.
