Parallel AdderIn digital circuit addition process is biggest and very important process. With the help of this method digital equipment perform various types of operation such as addition multiplication etc. on the basis of working principle there are two types of adder (1) Serial adder (2) ...
A NOVEL DESIGN OF REVERSIBLE SERIAL AND PARALLEL ADDER/SUBTRACTOR Under ideal conditions, Reversible logic gates produce zero power dissipation. So these can be used for low power VLSI design. This paper proposes a new re... D Krishnaveni.,PM Geetha - 《International Journal of Engineering Scien...
It requires a complementer and N/2 cells, each of which contains a ripple-carry adder and some gates, where N is restricted to even. The number of clocks required to multiply an n-bit (n ≤ N) multiplier and an m-bit multiplicand is equal to n + m − 1, and independent of ...
of inputs to produce a single sum result. You can add or subtract more than two operands and automatically shift the input operands upon entering the function. The method of shifting input operands is useful for serial FIR filter structures requiring a shift-and-accumulate of the partial ...
Serial tetrad adder/subtractor mechanism in BCD 8421 code The subject-matter of the invention is a serial electronic tetrad adder/subtractor mechanism in BCD 8421 code, which can be switched from addition to subtr... M Paul 被引量: 0发表: 1983年 Digital design width CPLD Application and VHDL...
While this second multiplication is being performed, the partial product and carry bits from the first multiplication are being shifted out of the shift registers to an adder which combines these bits to derive the final product bits. Multiple multiplicand storage registers are provided for allowing...
and an adder for adding the partial products to provide the product. The adder outputs a digit serial word that contains the least significant bits of an intermediate sum of the partial products as the partial products are being added. The digit serial adder includes a carry save adder that ...

A residual signal being an output of the subtractor circuit 3 is converted into a current signal by a voltage-current conversion circuit 5 and a low-order N2-bit is obtained by the subordinate A/D converter 6. An adder 7 is used to add the high-order N1 bit and the low- order N2 ...
It is a serial adder. It has a huge delay problem. With the use of half adder, full adder delay increases. Three types of carry-tree adders (the Kogge- Stone, Brent Kung, Han Carlson and Harris adder) in this paper investigates and compares them to the simple Ripple Carry Adder (RCA...
