Memory Map Analyzer

Principle

When a MicroEJ Application is linked with the MicroEJ Workbench, a Memory MAP file is generated. The Memory Map Analyzer (MMA) is an Eclipse plug-in made for exploring the map file. It displays the memory consumption of different features in the RAM and ROM.

Functional Description

In addition to the executable file, the MicroEJ Platform generates a map file. Double click on this file to open the Memory Map Analyzer.

Dependencies

No dependency.

Installation

This tool is a built-in SDK tool.

Use

The map file is available in the MicroEJ Application project output directory.

Select an item (or several) to show the memory used by this item(s) on the right. Select “All” to show the memory used by all items. This special item performs the same action as selecting all items in the list.

Select an item in the list, and expand it to see all symbols used by the item. This view is useful in understanding why a symbol is embedded.
