- Embedded cores are gaining widespread use to deal with the complex DSP systems where flexibility is of utmost importance. The design of such a system offers several problems, which are not addressed by the existing methodology. The authors previously presented an integrated grammar based DSP design methodology that separates architectural and functional specification, can create a virtual prototype and has a smooth link to the implementation phase. In this paper we present the extension of the work to handle embedded cores. Here we the capture the host peripheral interface (HPI) of TMS320C6x core at higher level of abstraction and provide a single simulation environment, which facilitates faster analysis of hardware software components. Our results reveal that the proposed methodology offers simulation time speed-up of 5 times and design time speed-up of 8 times, while keeping the architectural specification separated from functionality

- In this paper, we systematically define three transaction level models (TLMs), which reside at different levels of abstraction between the functional and the implementation model of a DSP system. We also show a unique language support to build the TLMs. Our results show that the abstract TLMs can be built and simulated much faster than the implementation model at the expense of a reasonable amount of simulation accuracy.

Konferensbidrag (refereegranskat)abstract
- Expensive top-down iterations are often required in the design cycle of complex DSP systems. In this paper, we introduce two levels of abstraction in the design flow by, systematically categorizing the architectural decisions. As a result, the top-down iteration loop is broken. We also present a technique to capture and inject the architectural decisions such that the system models can be created and simulated efficiently. The concepts are illustrated by a realistic speech processing example, which is implemented using the AMBA on-chip architecture. Our methodology offers a smooth path from the functional modeling phase to the implementation level, facilitates the reuse of HW and SW components, and enjoys existing tool support at the backend.
