Description
The Belle II experiment at the SuperKEKB collider in Japan has been under the construction toward a physics run in 2017 with 40 times higher instantaneous luminosity than the KEKB collider.
The main physics motivation is to search for the New Physics from heavy flavor decays.
In order to select an event of interest efficiently from much higher luminosity and beam background conditions than the KEKB, we have upgraded the Electromagnetic Calorimeter (ECL) hardware trigger system.
It will be realized by improving ECL trigger logic based on two main triggers, the total energy and the number of clusters, with a FPGA-based flexible architecture and a high speed serial link for the data transfer.
We report the current hardware, software, and firmware status that has been achieved so far.
The overall scheme of the system will be presented as well.
