Chernyak O. The pipe-line methods and means of full-function bit-serial arithmetic with reduced hardware expenses

Object of research - the process of bit-serial pipe-line arithmetic operations perfomanse, the purpose of work - to reduce of hardware expences, the used methods - multiple theory, coding theory and theory of automatic mashines; theoretical results - the notations for order-serial pipe-line perfomance of all arithmetic operations, are first offered; the pipe-line method of golden 1-ratio codes bit-serial adding is improved, which differs by using of sign-and-magnitude golden 1-ratio codes in any forms with signs located after senior units; the pipe-line method of golden 1-ratio codes bit-serial multiplication is improved, which differs that in it with help of a little three-input bit-serial adders sequences adding the all partial products; the pipe-line method of golden 1-ratio codes bit-serial division is improved, which differs that at each stage in the second step after devider's senior digit reception by analysis it next order the present order of result is defined. The practical results - the pipe-line devices with reduced hardware expences for bit-serial addition, subtraction, addition-subtraction with signs, multiplication and division in golden 1-ratio codes, also as method and the device for calculation of linearity error ADC in golden 1-ratio codes are offered. Introduction degree - the results are introduced at the Russian scientific-reseach institute of space instrument making and at the Electronics and communication institute of Ukrainian academy of sciences. Sphere of use - specialised computing means for development of analog-to-digital convertion results.
