LISA was initially developed at Institute for Integrated Signal Processing Systems (ISS) Aachen, belonging to RWTH Aachen University, in Germany. The current official version from RWTH Aachen is LISA 2.0. The language is still in evolution to cover research on processors, including Reconfigurable computing (in LISA 3.0), multi-core, parallel programming.
One noticeable branch called LISA+ has been created for handling the modeling of peripherals such as interrupt controllers, timers, etc.1
