Abstract

Reconfigurable hardware has been shown to provide an efficient compromise between the flexibility of software and the performance of hardware. However, even coarse-grained reconfigurable architectures target the general case, and miss optimization opportunities present if characteristics of the desired application set are known. We can therefore increase efficiency by restricting the structure to support a class or a specific set of algorithms, while still providing flexibility within that set. By generating a custom array for a given computation domain, we explore the design space between an ASIC and an FPGA. However, the manual creation of these customized reprogrammable architectures would be a labor-intensive process, leading to high design costs. Instead, we propose automatic reconfigurable architecture generation specialized to given application sets. The Totem custom reconfigurable array generator is our initial step in this direction.
