Abstract :
A new FPGA architecture and its VLSI implementation for bit-serial circuits are described. Its LUT (lookup table) is equipped with a shift register function that can efficiently implement bit-serial circuits. Comparisons against Xilinx XC4000XL FPGAs shows the effectiveness of this new FPGA architecture on bit-serial circuits.
