A transistor-level design of an asynchronous single-precision floating-point arithmetic unit is designed and tested using Cadence software. It uses CMOS (complementary metal oxide semiconductor) and DCVS (differential cascode voltage switch) logic in a 0.35 um process. Dual-rail signals are used for data, and control signals use four-phase handshaking and are mostly single-rail. Layouts of some of the unit's datapath and control blocks are created and tested. The unit handles single-precision addition, multiplication, division, and remainder using the IEEE 754-1985 Standard for Binary Floating-Point Arithmetic, with rounding and other operations to be handled by separate hardware or software. Division and remainder are done using a restoring subtractive algorithm; multiplication uses an additive algorithm. Exceptions are noted by flags (and not trap handlers) and the output is in single-precision. Previous work on asynchronous floating-point arithmetic units have mostly focused on single operations such as division. This work performs four floating-point operations using a common datapath. As such, it can serve as a basis of comparison for future work Subject Added Entry - Topical Term Asynchronous circuits -- Design and construction -- Data processing   Floating-point arithmetic -- Data processing   Computer arithmetic Collection Category FI   UP Location UP DARCHIVES LG 995 2003 E64 N63 Regular Circulation UARD-10668T   UP DENG-II LG 995 2003 E64 N63 E2000000284 Room-Use Only E-504T   UP DARCHIVES LG 995 2003 E64 N63 Regular Circulation UARD-10668T   UP DENG-II LG 995 2003 E64 N63 E2000000284 Room-Use Only E-504T Textual Physical Form Designator Thesis           Physical Location University of the Philippines Diliman Main Library: University Archives LG 995 2003 E64 N63 Diliman: College of Engineering Library II LG 995 2003 E64 / N63           Digital Copy Not Available          Add to Book Cart  |   Download MARC
