—Tools to design hardware at a high level of abstraction promise software-like productivity for hardware designs. Among them, tools like Spiral, HDL Coder, Optimus and MMAlpha target specific application domains and produce highly efficient implementations from high-level input specifications in a Domain Specific Language (DSL). But, developing similar(More)
—Field Programmable Gate Arrays (FPGAs) are very versatile devices, but their complicated programming model has stymied their widespread usage. While modern High-Level Synthesis (HLS) tools provide better programming models, the interface they offer is still too low-level. In order to produce good quality hardware designs with these tools, the users are(More)
In floating-point datapaths synthesized on FPGAs, the shifters that perform mantissa alignment and normalization consume a disproportionate number of LUTs. Shifters are implemented using several rows of small multiplexers; unfortunately, multiplexer-based logic structures map poorly onto LUTs. FPGAs, meanwhile, contain a large number of multiplexers in the(More)
