Green Mountain Computing Systems, Inc. is a Vermont company specializing in language based technologies since 1994. Our recent focus is in the area of natural language processing (NLP) such as our leading-edge sentiment analysis pipeline. Foundational to our NLP pipeline, LexicaDB is a modern in-memory database designed for relational graph datasets such as the WordNet English lexicon.
Green Mountain Computing Systems also has a long history in programming languages with a series products supporting the VHDL hardware-design language (http://www.gmvhdl.com). In 1999, we released VHDL Studio, the first VHDL design suite to include incremental analysis to provide on-the-fly error detection and advanced design navigation. DirectVHDL has evolved from the VHDL Studio product to be an ideal tool for learning VHDL.
