Largest atomic size: floating-point

Largest floating-point data type supported for atomic loading and storage on test hardware

Model Configuration Pane: Hardware Implementation

Description

The Largest atomic size: floating-point parameter specifies the largest floating-point data type that can be atomically loaded and stored on the hardware that you use to test code. Use this parameter, where possible, to remove unnecessary double-buffering or unnecessary semaphore protection, based on data size, in generated multirate code.

Selecting a device by using the Device vendor and Device type parameters sets a device-specific value for this parameter.

Dependencies

This parameter is enabled only if you can modify it for the selected hardware.

Settings

Float (default) | Double | None

Float: Specifies that float is the largest floating-point data type that can be atomically loaded and stored on the hardware that you use to test code.
Double: Specifies that double is the largest floating-point data type that can be atomically loaded and stored on the hardware that you use to test code.
None: Specifies that there is no applicable setting or not to use this parameter in generating multirate code.

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.
