Pack Boolean data into bitfields
Control storing Boolean signals
Model Configuration Pane: Code Generation / Optimization
Description
The Pack Boolean data into bitfields parameter specifies whether Boolean signals are stored as one–bit bitfields or as a Boolean data type.
Note
You cannot use this optimization when you generate code for a target that specifies an explicit structure alignment.
Settings
off (default) | on- On
Stores Boolean signals into one–bit bitfields in global block I/O structures or DWork vectors. This will reduce RAM, but might cause more executable code.
- Off
Stores Boolean signals as a Boolean data type in global block I/O structures or DWork vectors.
Recommended Settings
