Abstract
The complexity of DSP systems grows at an ever-increasing rate while the implementation of these designs must meet criteria like minimum cost and a short time to market. Hence there is a growing need for efficient design automation and a seamless design flow that allows the execution of the design steps at the highest suitable level of abstraction.
Especially for the design of fixed-point algorithms and systems, tool support is very rare, though for most digital systems the design has to result in a fixed-point implementation. This is due to the fact that these systems are sensitive to power consumption, chip size and price per device. Fixed-point realizations outperform floating-point realizations by far with regard to these criteria. On the other hand, algorithm design starts from a floating-pointdescription in order to initially abstract from all fixed-point effects. The resulting gap between the floating-point prototype and the fixed-point implementation represents one of the major bottlenecks in today’s digital designs.
This paper will give a survey of FRIDGE1, a tool suite that permits a seamless design flow, starting from an ANSI-C floating-point algorithm which is then converted to a fixed-point description in fixed-C2. This bit-true description of the algorithm can finally be mapped to different implementation targets, programmable DSPs or dedicated hardware structures.
