Computing registers
WebFour 32-bit data registers are used for arithmetic, logical, and other operations. These 32-bit registers can be used in three ways −. As complete 32-bit data registers: EAX, EBX, ECX, EDX. Lower halves of the 32-bit registers can be used as four 16-bit data registers: AX, BX, CX and DX. Lower and higher halves of the above-mentioned four 16 ...

WebDec 2, 2024 · BX is also the only 16-bit-addressing-mode register that has a low/high half. So maybe in 8086 it was physically on the boundary between the split low/high registers and the address-capable registers that the AGU had to read.

The Carry output is '0' unless both the inputs are 1. 'S' represents the least significant bit of the sum. The simplified sum of products (SOP) expressions is: S = x'y+xy', C = xy. The logic diagram for a half-adder circuit can be ...
