Low-Power Booth-Encoded Carry-Save Array Multiplier
- Technology Benefits
- The new UC technology provides the following benefits: Reduces power dissipation by 18% when the Booth-encoded input has a small magnitude; Does not dissipate extra power when the Booth-encoded input is a random signal; Does not require extra circuits or additional routing overhead; Does not require extra circuit delay.
- Technology Application
- This new UC invention is useful in digital integrated circuit (IC) design for digital signal processing applications.
- Detailed Technology Description
- Scientists at the University of California have developed a novel "reorganized" but regular partial-product addition scheme that demonstrates all of the advantages of the traditional carry-save array while reducing power dissipation.

BACKGROUND
Multipliers for digital signal processing (DSP) applications widely use the well-known modified Booth-encoding algorithm due to its ability to reduce the number of partial products. As the interconnect power dissipation begins to dominate in deep sub-micron designs, the regular structure of the carry-save array makes it the preferred method for partial-product reduction.
