Abstract:
|
A recently proposed architecture of redundant
binary fixed-width multiplier was shown to outperform several
normal binary fixed-width multipliers in terms of accuracy.
However, its merit due to the carry-free addition property of the
binary signed digit (BSD) partial products has been offset by the
high area overhead of the redundant binary full adder tree. To
achieve low–error fixed-width multiplication with smaller silicon
area, we propose a hybrid structure which makes use of dual
polarity high order column compressors and (3:2) counters to
parallelly reduce the positive and negative BSD partial products.
Our proposed technique has led to a fixed-width multiplier
architecture with the same accuracy and up to 42% area saving
for 10×10-bit multiplication over the conventional redundant
binary fixed-width multiplier architecture in 0.18 m CMOS
standard cell implementation under the same timing constraint. |
