Memcpy threshold (bytes)

Description

Specify the minimum array size in bytes for which memcpy and memset function calls should replace for loops for vector assignments in the generated code.

Category: Optimization

Settings

Default: 64

Note

The maximum value of the Memcpy threshold (bytes) parameter is 2147483647 bytes. If you set the parameter value at more than the maximum value, it automatically changes back to 2147483647 bytes.

Dependencies

This parameter requires a Simulink^® Coder™ license.
For the memcpy optimization, this parameter is enabled when you select Use memcpy for vector assignment.
