In this paper we describe ASH, an architectural framework for implementing Application-Specific Hardware. ASH is based on automatic hardware synthesis from high-level languages. The generated circuits use only localized computation structures; in consequence, we expect these circuits to be fast, to use little power and to scale well with program complexity. We present in detail CASH, a scalable compiler framework for ASH, which generates hardware from programs written in C. Our compiler exploits instruction level parallelism by using aggressive speculation and dynamic scheduling. Based on this compilation scheme, we evaluate the computational resources necessary for implementing complex integer-based programs, and we suggest architectural features that would support the ASH framework.
