Abstract: A fast 64 bit parallel binary adder for high performance microprocessors and DSP processors is described. It is implemented in UMC 2.5 V 0.25 /spl mu/m 1-poly 5-metal CMOS technology. A new ...

FOUR_BIT_PARALLEL_ADDER F1(a[0],b[0],cin,s[0],cout[0]); FOUR_BIT_PARALLEL_ADDER F2(a[1],b[1],cout[0],s[1],cout[1]); FOUR_BIT_PARALLEL_ADDER F3(a[2],b[2],cout[1],s[2 ...

This 2-bit adder was a lot of work to build. It uses a total of thirty-six 555 timers and it does have the option of adding or subtracting numbers. It’s a rather unorthodox use of the part, depending ...

Abstract: This paper presents a fast, low-power, binary carry-lookahead, 64-bit dynamic parallel adder architecture for high-frequency microprocessors. The adder core is composed of evaluate circuits ...
