A Wallace tree is an efficient hardware implementation of a digital circuit that multiplies two integers, devised by the Australian Chris Wallace in 1964.
Cabin coding is an effective method for the multiplication of both ... Verilog Simulation Results. LVS for the final chip. The multiplication operation is present in many parts of a digital system or digital computer, especially in signal processing, graphics and scientific computing. With advances in technology, several techniques have been proposed to design multipliers, which offer high speed, low power consumption and smaller area. Therefore, making them suitable for several high-speed, low-power compact VLSI implementations. These three parameters, ie power, area and speed, are always interchanged. This thesis work is dedicated to the design and simulation of Radix-8 Booth Encoder multiplier for signed and unsigned numbers. The Radix-8 Encoders circuit generates n / 3 parallel products. By extending the sign bit of the operands and generating an additional partial product, we obtain the Radix-8 Booth coder unsigned multiplier. The Carry Save Adder (CSA) tree and the final Carry Look Ahead (CLA) aggregator used to accelerate the multiplier operation. Since the signed and unsigned multiplication operation is performed by the same multiplier unit, the required hardware and chip area are reduced and this in turn reduces the power dissipation and cost of a system. Verilog multiplier encoding for signed and unsigned numbers using the Radix-4 encoder and the Radix-8 encoder for 8X8 bit multiplication and its FPGA implementation by the Xilinx Synthesis Tool in the Spartan 3 kit has been performed. The output is Has been displayed on the LED of the Spartan 3 kit.
