MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Aside from the four segment registers introduced in the previous section, the 8086 has seven general purpose registers, and two status registers. The general purpose registers are divided into two categories. Four registers, AX, BX, CX, and DX, are classified as data registers.

Detailed explanation-2: -The 8086 has 8 general-purpose registers, each of which is 16 bits wide. They are ax, bx, cx, dx, si, di, bp and sp. cx (Count Reg) : Used for counting purposes, like number of iterations while looping, number of characters in a string, etc.

Detailed explanation-3: -The registers inside the 8086 are all 16 bits. They are split up into four categories: General Purpose, Index, Status & Control, and Segment. The four general purpose registers are the AX, BX, CX, and DX registers.

Detailed explanation-4: -The 8086 has 14 16 bits registers. AX, BX, CX, DX, SI, DI, BP, SP, CS, DS, SS, ES, IP and the flags register. The last two are only accessed indirectly.

Detailed explanation-5: -The 8 general-purpose registers of CPU that are capable of storing 32-digit binary numbers. In addition to 32-bit data, they can also store 16-or 8-bit data.
