Chapter 4
Inspection Configuration
4–30
Here is a brief description of the data fields that appear above the check
boxes in the toolset edit panel:
•
Tools –– This field indicates the number of inspection tools in the current
toolset edit panel. The example toolset edit panel in Figure 4.22 (page
4–27) shows this as
1 Tool .
•
*Tool bytes –– The first part of this field indicates the amount of memory
bytes required by the current set of tools in the toolset edit panel, while
the second part shows the total amount of system memory available for
tools. The example toolset edit panel in Figure 4.22 (page 4–27) shows
this as
408/65536 Tool bytes .
•
*Results bytes –– The first part of this field indicates the amount of
memory dedicated to tool results for the current set of tools in the toolset
edit panel, while the second part shows the total amount of system
memory available for tool results. The example toolset edit panel in
Figure 4.22 (page 4–27) shows this as
360/32768 Results bytes .
*The CVIM2 system automatically allocates memory space for tools and tool
results as needed. If additional memory is required for a toolset or for results,
refer to Appendix B and the Variables section of Chapter 10 (page 10–3) for
information about setting environment variables.
Destination Buffers
A destination buffer (such as P1 or B1 ) is required for an image tool, profile
tool, and rotation finder tool, since the main function of these tools is to
supply processed images either to themselves or to other tools that follow
them in the same toolset.
A destination buffer must be selected for any window tool that is to be
configured to use the
Two Pass function. In this case, the destination buffer
must be selected in the toolset edit panel before the Two Pass function can
be enabled in the window tool’s tool edit panel. In addition, a destination
buffer can be selected for a window tool when the only function of the buffer
is to provide a processed image source for tools that follow the window tool
in the toolset edit panel.
The two types of buffer, P1 , P2 , and P3 , and B1 , B2 , and B3 , perform the
same function of storing a processed image; however, they differ in their
duration of storage. The Px buffers are always released at the end of the
current inspection cycle, while the Bx buffers can be used in some
circumstances to store a processed image beyond the current instruction
cycle, and make it available to subsequent inspections.
