Towards An Automated Approach to Hardware/Software Decomposition

We propose in this paper an algebraic approach to hardware/software partitioning in Verilog Hardware Description Language (HDL). We explore a collection of algebraic laws for Verilog programs, from which we design a set of syntax-based algebraic rules to conduct hardware/software partitioning. The co-specification language and the target hardware and software description languages are specific subsets of Verilog. Through this, we confirm successful verification for the correctness of the partitioning process by an algebra of Verilog. Facilitated by Verilog’s rich features, we have also successfully studied hw/sw partitioning for environment-driven systems.
