This paper describes the high level microprogramming language (ML) used in microprogramming the FCPU (Flexible Central Processing Unit) developed by the Datasaab sector of Saab-Scania AB. The background of the use of machine dependent high level languages is discussed. The global structure and microinstruction organization of the FCPU are presented. The structure of the ML and microprograms are introduced followed by an example of the use of ML. A summary of the syntactical structure of FCPU microinstruction statements and the FCPU facilities are presented in an appendix.
