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

) 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,

, and

, 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.
