....compiler implementation, for example, a particular intermediate representation. Architecture descriptions for embedded processors, for example, the DSP processors and application specific instruction set processors (ASIPs) have also received intense interest in the recent years. MIMOLA [3] used a hardware description language to describe the structural model of the processor, code selection and register allocation can then performed by pattern matching. Since ILP can be concisely represented using a structural model, some recent work adopted a similar approach. For example, CHESS ....

....features such as predicated and speculative execution. Architecture descriptions for irregular processors, for example, the DSP processors and and application specific instruction set processors (ASIPs) also receive intensive interest in the recent years. Representative works are MIMOLA [9], where a hardware description language is used to describe the structural model of the processor; as well as nML [12] and ISDL [11] which take a more traditional approach. Representing a more recent effort, the Expression [13] architecture description language uses both the behavioral level ....

....between the architectural model and the synthesis tool is difficult to define. Despite its uniqueness, our work is in many ways inspired by the previous works. The concept of implicitly representing the instruction set of a processor using a structural description, was first proposed in MIMOLA [9] and detailed in [10] Expression [13] also uses the same concept to reduce the size of processor specification. Our work differs in that we extend this concept to the FSMD architecture, and our structural specification is abstract, parameterized and partially constrained. Our model for ILP is an ....

It supports design, test, simulation and programming of digital computers and is integrated into the CAD system MSS [19, 20]. MIMOLA, influenced by other hardware description languages like VHDL [15] allows structural and behavioral descriptions of circuits. Originally the complete system was written in Pascal but beginning with MIMOLA 4.0 we started to redesign tools using Prolog. Using the extended Prolog system ....

The Mimola design system was originally conceived as a design environment for hardware structures using the Mimola hardware description language [15] It later evolved into an environment for hardware software co design and includes a retargetable microcode compiler [11] [16] One of the key features that distinguishes the Mimola project from others is that the microcode compiler infers rules for code generation directly from a structural description (e.g. a net list) of the target architecture instead of a behavioral description (e.g. the instruction set) The ....

The simulator is able to simulate a processor together with a given program and is based on three levels of abstraction: the built in operators, an interpreter for the behaviour of single components and an event driven simulator for circuits together with microcode. ....
