I came across some code in the LISA language while working on an ARM based project. The code look much similar like a mix of VHDL and C++. I tried to google out to get an introduction to the language. I couldn't find much help.If some one has good experience in LISA please guide in the approach to be taken in understanding the language design or basically what will be a good starting point to master it . I got a link to the university where this has been found https://www.ice.rwth-aachen.de/research/tools-projects/lisa/lisa/
But on understanding this as a language(basically how to code in it) the information provided there is insufficient I feel . We don't even have a tag for this in SO!!
To answer your question -
"LISA is a descriptive programming language and not object oriented"
You can go through this Paper - LISA Machine Description Language and Generic Machine Model for HWSW CoDesign for more details. The language has not been yet standardized by IEEE and ISO yet and is in its enhancement phase.
