In this paper, a new functional unit called the calculation and anticipation (C&amp;A) unit is presented for the IEEE 754 standard floating-point adder (FPA) that is the most important and frequently used calculation part for both modern CPUs and GPUs. C&amp;A unit parallelize rounding step and readjustment step, which are known as the time-consuming steps for floating-point addition with significand addition. Therefore it reduces FPA critical path delay enormously, and even more decreases a little FPA area occupation. The synthesis results show that the double-precision FPA with C&amp;A unit takes about 17.17% improvement in the critical path delay, while saves about 8.32% area than the conventional one. It takes 5.90% advantage in area and 19.58% improvement in the worst case delay than the double-precision FPA from the Open Core module \"fpu_double\" (rev 14 2010-02-13) synthesized in the same 0.13-\u03bcm CMOS bulk. Furthermore, comparing with the two-path double-precision FPA synthesized using LSI Logic's gflxp 0.11-\u03bcm CMOS library, it takes about 4.30% advantage in the critical path delay, and saves almost one-third area in the number of the individual cells. <\/jats:p>","DOI":"10.1142\/s0218126615500292","type":"journal-article","created":{"date-parts":[[2014,11,30]],"date-time":"2014-11-30T21:31:52Z","timestamp":1417383112000},"page":"1550029","source":"Crossref","is-referenced-by-count":0,"title":["The Calculation and Anticipation Unit for Floating-Point Addition"],"prefix":"10.1142","volume":"24","author":[{"given":"Linghao","family":"Li","sequence":"first","affiliation":[{"name":"Electronic and Information Engineering School, Xi'an Jiao Tong University, Xi'an 710049, P.
