Number of bits: long long

R2026b

Bit length of C long long data type for selected hardware

Model Configuration Pane: Hardware Implementation

Description

The Number of bits: long long parameter describes the length in bits of the C long long data type for the selected hardware. Use the C long long data type only if your C compiler supports long long.

Dependencies

This parameter is enabled only if both of these conditions are true:

  • Enable long long is selected.

  • The selected hardware supports modification of this parameter.

Settings

64 (default) | 72 | 80 | 88 | 96 | 104 | 112 | 120 | 128

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

Only custom targets support modifying this parameter. The value must be a multiple of 8 between 64 and 128, inclusive. The value must be greater than or equal to the value of Number of bits: long.

Safety precaution

No recommendation for simulation without code generation.
For simulation with code generation, select your Device vendor and Device type if they are available in the drop-down list. If your Device vendor and Device type are not available, set device-specific values by using Custom Processor.
