Carry Prediction and Selection for Truncated Multiplication


This paper presents an error compensation method for truncated multiplication. From two $n$-bit operands, the operator produces an n-bit product with small error compared to the 2n-bit exact product. The method is based on a logical computation followed by a simplification process. The filtering parameter used in the simplification process helps to control the trade-off between hardware cost and accuracy. The proposed truncated multiplication scheme has been synthesized on an FPGA platform. It gives a better accuracy over area ratio than previous well-known schemes such as the constant correcting and variable correcting truncation schemes (CCT and VCT).
