Extendable squarer and operation method for processing digital signals

摘要

An extendable squarer for processing digital signals, suitable for processing a square operation for n-bit data is disclosed. The extendable squarer comprise a bit expanding circuit and a plurality of operating units. The bit expanding circuit comprises n-1 bit expanding output terminals for outputting a plurality of bit expanding data. The operation units receive a plurality of bit codes of the n-bit data corresponding thereto according to the binary weight. In addition, except for bit code of the most-significant bit, the other operation units receive the corresponding bit expanding data output by the bit expanding circuit respectively. The present invention generates the square operation value of the n-bit data based on the corresponding bit expanding data and bit codes.
