Memory configuration: Heap memory

Memory requirements
RESU requires compile cycles heap memory for the following function-specific buffers:
• Block buffer
• Block search buffer
Figure 2-4
14
The larger the block buffer (see Fig. "RESU program structure") the more part program
blocks can be traversed in reverse. 32 bytes are required per part program block. The
block buffer can be parameterized directly.
The block search buffer contains the information required for processing subroutine
searches in the context of RESU. 180 bytes are required for each subroutine. The block
search buffer requires at least 2160 bytes (12 subroutine calls with 180 bytes each). The
block search buffer cannot be parameterized directly. The size of the block search buffer
is displayed via a function-specific GUD variable.
To create the GUD variables, please refer to:
Chapter "Function-specific display data / channel-specific GUD variables".
