Framework of Converting C plus plus Class to Hardware

In recent SOPC (System on Programmable Chip) design, a system becomes very complex and the cost of modifying the design during the development becomes very expensive. Based on the technology of the C to HDL (Hardware Description Language), we propose a framework to convert C++ class to hardware, which can be used to cope with the change of design requirement during the development period. Within this framework, software and hardware components can be switched to each other easily, and can be reused between different projects as an object-oriental component.
