A REDUNDANT ADDER STRUCTURE SUITABLE FOR THE NEW GENERATION RECONFIGURABLE FPGA ARCHITECTURES
Öz
Arithmetic operations are generally slowest operations in digital design which is the
bottleneck in most of the systems. Optimizing adder circuits provides faster
performance in arithmetic circuits. Field Programmable Gate Arrays (FPGA) are very
popular to implement logic circuits. 6-input Look-Up Table (LUT) devices are on the
market which dramatically increases the performance. In this paper, alternative
addition structures, based on redundant carry-free arithmetic and suitable for 6 input
LUT devices, are presented. A new double carry-save addition architecture is proposed,
which reduces the critical path of the addition process for 6-input LUT devices.
