Bitfield declarator type specifier - Specify bitfield type - MATLAB (original) (raw)
Main Content
Model Configuration Pane: Code Generation / Optimization
Description
The Bitfield declarator type specifier parameter specifies the bitfield type when selecting configuration parameter Pack Boolean data into bitfields. The optimization benefit is dependent upon your choice of target.
Dependencies
The Pack Boolean data into bitfields parameter enables this parameter.
Settings
uint_T (default) | **uchar_T**
uint_T
The type specified for a bitfield declaration is an unsigned int.
uchar_T
The type specified for a bitfield declaration is an unsigned char.
Tips
The Pack Boolean data into bitfields configuration parameter default setting uses unsigned integers. This might cause an increase in RAM if the bitfields are small and distributed. In this case, uchar_T might use less RAM depending on your target.
Recommended Settings
