Abstract:
Decimal multiplication is an integral part of
financial, commercial, and internet-based computations.
This paper presents a novel double digit decimal
multiplication (DDDM) technique that offers low latency
and high throughput. This design performs two digit
multiplications simultaneously in one clock cycle. Double
digit fixed point decimal multipliers for 7digit, 16 digit and
34 digit are simulated using Leonardo Spectrum from
Mentor Graphics Corporation using ASIC Library. The
paper also presents area and delay comparisons for these
fixed point multipliers on Xilinx, Altera, Actel and Quick
logic FPGAs. This multiplier design can be extended to
support decimal floating point multiplication for IEEE 754-
2008 standard.

Abstract:
Decimal multiplication is an integral part of financial,
commercial, and internet-based computations. This paper
presents a novel double digit decimal multiplication
(DDDM) technique that performs 2 digit multiplications
simultaneously in one clock cycle. This design offers low
latency and high throughput. When multiplying two n-digit
operands to produce a 2n-digit product, the design has a
latency of (n / 2) 1 cycles. The paper presents area
and delay comparisons for 7-digit, 16-digit, 34-digit double
digit decimal multipliers on different families of Xilinx,
Altera, Actel and Quick Logic FPGAs. The multipliers
presented can be extended to support decimal floating-point
multiplication for IEEE P754 standard
