Pre-Encoded Multipliers Based on Non-Redundant Radix-4 Signed-Digit Encoding - 2016
In this project, we introduce an architecture of pre-encoded multipliers for digital signal processing applications based on off-line encoding of coefficients. To this extend, the Non-Redundant radix-4 Signed-Digit (NR4SD) encoding technique, that uses the digit values -1,0,+1,+2 or -2,-1,0,+1 , is proposed resulting in a multiplier design with less complex partial products implementation. In depth experimental analysis verifies that the proposed pre-encoded NR4SD multipliers, including the coefficients memory, are additional space and power efficient than the traditional Modified Booth theme.
