  A complete dedicated electronics, from front-end to back-end, was developed
to instrument a MIMAC prototype. A front end ASIC able to monitor 64 strips of
pixels and to provide their individual "Time Over Threshold" information has
been designed. An associated acquisition electronics and a real time track
reconstruction software have been developed to monitor a 512 channel prototype.
This auto-triggered electronic uses embedded processing to reduce the data
transfer to its useful part only, i.e. decoded coordinates of hit tracks and
corresponding energy measurements. The electronic designs, acquisition software
and the results obtained are presented.
