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.
