Memory Mapping Profiler panel

This panel is used to display the memory mapping information of load modules collected by the build tool.

The amount of used memory can be reduced by analyzing the information.

Remark

This panel can be zoomed in and out by in the tool bar, or by moving the mouse wheel forward or backward while holding down the [Ctrl] key.

[Description of each area]

(1)	[Profiled memory mapping list] area

The memory mapping information of load modules collected by the build tool of the active project and the memory mapping information saved by the user are displayed.

The first item displays the memory mapping information collected by the build tool of the active project (item name: <Latest result of profiling>). When no information has been collected, "(Uncollected)" is added to the item name.

The second and subsequent items display the memory mapping information saved by the user.

(a)

Button

Switches between collecting and not collecting the memory mapping information at build.

When this button is ON, "(Collect)" is added to the button name and the memory mapping information that is output when build of the active project has completed will be collected.

When this button is switched from OFF to ON, CS+ checks whether to change the property values of build options to those suitable for profiling (only however in cases where property values can be changed).

This button automatically becomes OFF when the active project is switched.

Opens the Character String Input dialog box in order to save the latest result of profiling (collected result of memory mapping information) as a snapshot.

In the dialog box, specify the item name to be displayed in this area (maximum number of input characters: 100).

Note that the number of items that can be saved is 10.

Deletes the selected snapshot.

Note that <Latest result of profiling> cannot be deleted.

(2)	[Build options about the selected memory mapping] area

The build options used when generating the items selected in the [Profiled memory mapping list] area are listed.

(a)

Button

Imports the build options (except for individual options) used at the time of profiling the items selected in the [Profiled memory mapping list] area as the current build options.

Opens the Section Settings dialog box to edit the settings related to memory mapping by the build tool.

See "CS+ Integrated Development Environment User’s Manual: Build Tool Operation" for details about the Section Settings dialog box.

(3)	[Details of the selected memory mapping] area

The detailed memory mapping information of the items selected in the [Profiled memory mapping list] area are displayed as a list.

Note that the display contents depend on the build option settings of the build tool in use.The following lists the contents of the full display.

Tab	Description
Summary	Displays the amounts of ROM and RAM to be used. The ratio of memory consumption relative to the capacity of the device may also be shown; this depends on the type of build tool.
Load Module	Displays the sizes of each type of section (program, data, etc.).
Sections	Displays the name, size, group, start and end addresses, and alignment number of each section.
Object File	Displays the size, group, start and end addresses, and name of each section included in an object file (an input file for the linker; the name of a module in the *.obj file that includes the results of compilation or assembly of source code or in the user library).
Symbol	Displays the sizes of symbols (function names or variable names), the groups and start and end addresses of the sections to which the symbols belong, the types and scopes of symbols, section names, and object file names.

For details on the -SHow linker option and the link map file, refer to the "User's Manual: Compiler".

This area has the following functions.

(a)	Display the differential result

Differences between the two sets of memory mapping information can be displayed.

-	The item selected in the [Profiled memory mapping list] area is the comparison destination and the item whose check box is selected is the comparison source. The following string is displayed in the upper part of this area.

Comparing mode "Item name of comparison destination"(Selected Item) - "Item name of comparison source"(Checked Item)

Any string in which "Size" is included in the header name can be the target of difference calculation.
The cell displaying the differential result is highlighted (the character color/background color is set in the [General - Font and Color] category in the Option dialog box).
The sum of the values in each line is displayed at the bottom of the list.
