ABSTRACT:
A technique is disclosed for processing a binary coded signal to generate a thermometer coded signal. Such technique includes the following steps. A binary coded input signal is obtained. A binary arithmetic operation is performed on a least significant bit (LSB) portion of the binary coded input signal. At least one signal representative of an occurrence of one of an overflow condition and an underflow condition is generated, in response to the binary arithmetic operation performed on the LSB portion. A thermometer coded signal is shifted in response to the signal representative of the occurrence of one of the overflow condition and the underflow condition, wherein shifting of the thermometer coded signal represents one of incrementing and decrementing a most significant bit (MSB) portion of the binary coded input signal. The thermometer coded signal is outputted. Performance of the binary arithmetic operation on the LSB portion of the binary coded input signal and shifting of the thermometer coded signal in response to one of the overflow condition and the underflow condition results in elimination of a sign extension into the MSB portion of the binary coded input signal.
