Abstract
Application-specific processor (ASIP) design is a promising approach for meeting the performance and cost goals of an embedded system. We have developed a new microarchitecture for automatically constructing ASIP's. This new architecture, called a wide counterflow pipeline (WCFP), is based on the counterflow pipeline organization proposed by Sproull, Sutherland, and Molnar. Our ASIP synthesis technique uses software pipelining and design space exploration to generate a custom WCFP and instruction set for an embedded application. This type of architecture synthesis requires an infrastructure for rapidly prototyping ASIP's to evaluate design trade-offs. This paper presents the requirements and implementation of such an environment for automatic design of WCFP's. First, we describe a database for specifying design elements and architectural constraints. Second, we present an intermediate representation for WCFP synthesis and reconfigurable simulation. Finally, we describe a fast and reconfigurable simulation methodology for WCFP's.
