The performance of a corresponding hardware depends on the efficiency of the finite field arithmetic implementation. A good-quality finite field multiplier is needed first, since multiplication is an often-used and time consuming operation. Because FPGAs differ considerably in structure from other integrated circuits, the finite field multiplier designs, which are optimized for VLSI implementation, do not perform well on FPGAs. In this paper, some structures of a completely combinatorial GF(16) multiplier, based on 4-input LUTs and some other resources of the Xilinx FPGA, have been proposed. As a result, some improvement in area and time has been achieved by comparison with previous designs.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.

Datapath synthesis algorithms preserve these regular structures, so they can be exploited by packing, placement, and routing tools for speed or density. Typical datapath synthesis algorithms, however, sacrifice area to gain regularity. Current algorithms can have as much as 30% to 40% area inflation when compared with traditional flat synthesis algorithms. This paper describes a datapath synthesis algorithm with very low area overhead, which is an enhancement to the module compaction algorithm. We propose two word-level optimizations - multiplexer tree collapsing and operation reordering. They reduce the area inflation to 3%-8% as compared with flat synthesis. Our synthesis results also retain significant amount of regularity from the original designs.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.

Logic replication is known to be crucial for optimizing depth in technology mapping; an important contribution of our work is to recognize the effect of logic replication on circuit structure and to show its consequences on power. In an experimental study, we examine the power characteristics of mapping solutions generated by several publicly available technology mappers. Results show that for a specific depth of mapping solution, the power consumption can vary considerably, depending on the technology mapping approach used. Furthermore, results show that our proposed mapping algorithm leads to circuits with substantially less power dissipation than previous approaches.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.

The logic function operating on the first gate of a double gate (DG) transistor is reconfigured by altering the bias on its second gate. A compact reconfigurable cell is proposed that merges two stacked 3-state resonant tunneling devices and non-silicon transistors and \"hides\" the cost of reconfiguration by exploiting vertical integration. Each cell in the array can act as logic or interconnect, or both - contrasting with current FPGA structures in which logic and interconnect are built and configured largely as separate items. Simulation results for a SOI DG-MOSFET implementation is presented and two alternative non-silicon device technologies, metal-insulator-metal and carbon nanotube transistors, are briefly explored Of these, carbon nanotube devices appear to offer the highest current drive at the limit of scaling and will operate into the gigahertz range but then only within architectures that are locally connected.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.

Its basic premise is that the levels of design productivity needed to counter the intrinsic complexity of such embedded systems will only be achieved by extensive, planned design re-use. The platform concept originated with ASICs but evolved rapidly to FPGAs. In this paper, we investigate the phenomenon of FPGA platforms using the Xilinx Virtex/spl trade/-II Pro series of Platform FPGAs as our reference model. We identify and categorize their principal characteristics and seek to differentiate them from their ASIC predecessors. We make the case for regarding Platform FPGAs as meta-platforms because of the extent to which they extend the original concept of platform-based design. Looking forward, we offer some conjectures as to the nature of future FPGA platforms and some of the challenges that researchers will face.","PeriodicalId":355740,"journal":{"name":"2002 IEEE International Conference on Field-Programmable Technology, 2002.
