Abstract :
This paper presents an heuristic method to perform the high-level synthesis of multiple-precision specifications. The scheduling is based on the balance of the number of bits calculated per cycle, and the allocation on the bit-level reuse of the hardware resources. The implementations obtained are multiple-precision datapaths independent of the number and widths of the specification operations. As a result impressive area savings are achieved in comparison with conventional algorithms implementations.
