4 Bit Wallace Tree Multiplier Block Diagram. A wallace tree multiplier is much faster than the normal multiplier designs. Array multiplier booth recoded 16 2.
4 2 compressor block diagram fig. 4 2 compressor architecture c. It was devised by the australian computer scientist chris wallace in 1964.
Fig 11 shows the block diagram of wallace tree multiplier using csa and cska.
Input from neighboring cell other than the actual 1 bit inputs and thus in turn gives out a carry output. Line diagram for multiplication of two 4 bit numbers next all the four bits are processed with crosswise multiplication and addition to give the sum and carry. It was devised by the australian computer scientist chris wallace in 1964. Therefore it has used 16 and gates for multiplication.
