- As we move from algorithm on a chip to system on a chip era, the design bottleneck is shifting from individual DSP functions to global control that composes a system from these functions. The practice in industry suffers from global control entering the design flow too late, discontinuity between functional modeling and implementation phase and mixing data flow with global control. MASIC-Maths to ASIC-is a methodology proposed in this paper that targets DSP SOCs and addresses these issues. Global control is specified in a grammar notation and integrates the output of functional modeling phase, the DSP functions, by referencing them. A virtual prototype is automatically built from such a specification that models the global control in VHDL and cosimulates with the DSP functions in C from the functional modeling phase. A highly efficient verification methodology based on separating the verification of global control from DSP functions is proposed. A smooth path to cycle true implementation is possible using either behavioral synthesis, IPs for the DSP functions or manual implementation. Experiments using realistic examples like GSM base band processing, rake receiver and some smaller examples have been carried out to quantify the benefits of MASIC.

- Grammars define syntax of languages and as such have not been commonly considered as methods for design, despite well-known applications in computer science. Only in recent years grammar-based design has become a promising research field and the first commercial tools have appeared on the market. This paper reviews the basic concepts of applying grammars to electronic design - in particular to the device driver synthesis of communication protocols for embedded software, to the design of custom-hardware, and to the virtual prototyping of DSP systems. The paper shows the power of these methods, presents the latest research results and discusses future developments in this field.
