Arden-architecture development environment

Software supports, such as compiler and simulation tools, are increasingly crucial for architecture development. A flexible system called Arden is being developed to help evolve efficient architectures. Arden combines a retargetable compiler with a back-end simulation tool which provides quantitative information for making a good decision in architecture designs. User-oriented specification for the code generator has simplified the machine descriptions and requires only 31 rules in describing DLX architecture. An experimental bottom-up matching algorithm which reduces the pattern matching to a numerical computation problem and improves the space complexity is presented
