Design and Synthesis of High Speed Low Power Signed Digit Adders
Signed digit (SD) number systems provide the possibility of constant-time addition, where inter-digit carry propagation is eliminated. Such carry-free addition is primarily a three-step process; adding the equally weighted SDs to form the primary sum digits, decomposing the latter to interim sum digits and transfer digits, which commonly belong to {–1, 0, 1}, and finally adding the tra...
متن کاملHigh Speed and Low Power Implementation of FIR Filter Design using DADDA & WALLACE Tree Multiplier
The most area consuming arithmetic operations in high-performance circuit’s Finite Impulse Response (FIR) multiplication is one. We are using different types of multipliers to reducing the cost of effective parameters in FIR filter design. We use only truncated multipliers in design, by using these multipliers we consume some more area and power, and ineffective results in transposed form. The ...
متن کاملDesign of High-Speed Low-Power Parallel-Prefix VLSI Adders
Parallel-prefix adders offer a highly-efficient solution to the binary addition problem. Several parallel-prefix adder topologies have been presented that exhibit various area and delay characteristics. However, no methodology has been reported so far that directly aims to the reduction of switching activity of the carry-computation unit. In this paper by reformulating the carry equations, we i...
