Abstract
This paper presents an heuristic method to solve the combined resource selection and binding problems for the high-level synthesis of multiple-precision specifications. Traditionally, the number of functional (and storage) units in a datapath is determined by the maximum number of operations scheduled in the same cycle, with their respective widths depending on the number of bits of the wider operations. When these wider operations are not scheduled in such “busy” cycle, this way of acting could produce a considerable waste of area. To overcome this problem, we propose the selection of the set of resources taking into account the only truly relevant aspect: the maximum number of bits calculated and stored simultaneously in a cycle. The implementation obtained is a multiple-precision datapath, where the number and widths of the resources are independent of the specification operations and data objects. 1.
