Zusammenfassung (englisch): Decimal Floating Point operations are important for applications that cannot tolerate errors from conversionsbetween binary and decimal formats, for instance, commercial, financial, and insurance applications. In this paper, wepresent a parallel decimal fixed-point multiplier designed to exploit the features of Virtex-5 FPGAs. Our multiplier is basedon BCD recoding schemes, fast partial product generation, and a BCD-4221 carry save adder reduction tree. Pipelinestages can be added to target low latency. Furthermore, we extend the multiplier with an accurate scalar product unitfor IEEE 754-2008 decimal64 data format in order to provide an important operation with least possible rounding error. Compared to a previously published work, in this paper, we improve the architecture of the accurate scalar product unitand migrate to Virtex-5 FPGAs. This decreases the fixed-point multiplier's latency by a factor of two and the accuratescalar product unit's latency even by a factor of five.
