It is Mazda's mild hybrid technology. It uses a small Integrated Starter Generator (ISG) to capture energy that is normally wasted during braking and stores it to power the car's electrical systems, reducing the load on the engine and saving fuel in the process.
When you decelerate, the integrated starter motor generator produces electricity which is stored in a 24 volt battery. This electricity is used for a number of purposes including starting the engine and providing motor assistance when you pull away. It can also power the car's electrical systems.
