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

Use

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

Retrieve Map File

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.
