Flexible Application Specific Instruction set Processors (ASIP) are starting to replace monolithic ASICs in a vide variety of fields. However the design of an ASIP is today a substantial design effort. This paper discusses \({\ensuremath{\mathfrak{NoGap}}}\) (Novel Generator for ASIP) a tool for ASIP designs utilizing hardware multiplexed data paths. One of the main advantages of \({\ensuremath{\mathfrak{NoGap}}}\) compared to other ADL tools is that it does not impose limits on the architecture and thus design freedom. To reach this flexibility \({\ensuremath{\mathfrak{NoGap}}}\) makes heavy use of the compositional design principle and is therefore divided into three parts \(\mathfrak{Mage}\), \({\ensuremath{\mathfrak{Mase}}}\), and \({\ensuremath{\mathfrak{Castle}}}\). This paper presents the central concepts of \({\ensuremath{\mathfrak{NoGap}}}\) to show that it is possible to reach this advertised flexibility and still be able to generate HDL code and tools such as simulators and assemblers.
