With the advent of heterogeneous multi-processor system-on-chips (MPSoCs), hardware/software partitioning is again on the rise both in research and in product development. In this new scenario, implementing intellectual-property (IP) blocks as SW applications rather than dedicated HW is an increasing trend to fully exploit the computation power provided by the MPSoC CPUs. On the other hand, whole libraries of IP blocks are available as RTL descriptions, most of them without a corresponding high-level SW implementation. In this context, this article presents a methodology to automatically generate SW applications in C++, by starting from existing RTL IPs implemented in hardware description language (HDL). The methodology exploits an abstraction algorithm to eliminate implementation details typical of HW descriptions (such as, cycle-accurate functionality and data types) to guarantee relevant performance of the generated code. The experimental results show that, in many cases, the C++ code automatically generated in few seconds with the proposed methodology is as efficient as the corresponding code manually implemented from scratch.
