In 8085 name of the 16 bit registers is?

This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!

Program counter (PC) and Stack pointer (SP) are basically used to hold 16 – bit memory addresses. PC stores the 16-bit memory address of the next instruction to be fetched. SP can be used to temporarily store the 16 – bit memory address as well as data. So PC and SP are 16-bit registers.

What are the 16-bit registers available in 8085 microprocessor?

In 8085 microprocessor, the 16-bit registers used are:
  • Stack pointer and accumulator.
  • Program counter and accumulator.
  • Stack pointer and program counter.
  • Accumulator, stack pointer and program counter.

What is the name of 16-bit register in 8085 Mcq?

8) In 8085 name/names of the 16 bit registers is/are

stack pointer.

How many 16-bit registers are there?

Memory Registers There are two 16-bit registers used to hold memory addresses. The size of these registers is 16 bits because the memory addresses are 16 bits. They are: Program Counter This register is used to sequence the execution of the instructions.

Why is the PC & SP in 8085 are 16-bit registers?

Why is the program counter in 8085 microprocessor 16 bit register? The program counter acts as a pointer to the next instruction to be executed and always contains the 16-bit address of the memory location of next instruction.

Which register is 16-bit?

A 16-bit Data Segment register or DS register stores the starting address of the data segment. Stack Segment − It contains data and return addresses of procedures or subroutines. It is implemented as a ‘stack’ data structure. The Stack Segment register or SS register stores the starting address of the stack.

Why stack pointer is 8-bit?

Why does the stack pointer holds only 8 bit address in 8051 and whereas the program counter holds the 16 bit address? that is the way it was designed. It has only 128 bytes of RAM, so an 8-bit stack pointer is enough. Using external RAM is possible, but requires a special instruction (MOVX).

What are 16 bits called?

BYTE – 8 bits, unsigned. WORD – 16 bits, unsigned. DWORD – 32 bits, unsigned.

Is Al a 16-bit register?

The registers found on the 8086 and all subsequent x86 processors are the following: AX, BX, CX, DX, SP, BP, SI, DI, CS, DS, SS, ES, IP and FLAGS. These are all 16 bits wide. … These general purpose registers can also be addressed as 8-bit registers. So AX = AH (high 8-bit) and AL (low 8-bit).

Is Ax a 16-bit register?

AX – This is the accumulator. It is of 16 bits and is divided into two 8-bit registers AH and AL to also perform 8-bit instructions. It is generally used for arithmetical and logical instructions but in 8086 microprocessor it is not mandatory to have accumulator as the destination operand.

How many types of interfacing are there?

In general, interfacing comes in two main types, fusible or sew-in, as well as three main weaves (non-woven, woven and knit), and different weights. When designing your piece, it is important to make the right choice, as this decision can really influence the final look of your garment.

Which Stack is used in 8085?

Answer: LIFO (Last In First Out) stack is used in 8085.In this type of Stack the last stored information can be retrieved first.

What is the store by register?

The operands for all arithmetic and logic operations are contained in registers. To operate on data in main memory, the data is first copied into registers. A load operation copies data from main memory into a register. A store operation copies data from a register into main memory .

What are types of registers?

There are different types of Registers that are used. Some of the most used Registers are accumulator, data register, address register, program counter, memory data register, index register, and memory buffer register. The various operations are performed with the use of register.

How many registers are in 8086?

The 8086 has eight more or less general 16-bit registers (including the stack pointer but excluding the instruction pointer, flag register and segment registers). Four of them, AX, BX, CX, DX, can also be accessed as twice as many 8-bit registers (see figure) while the other four, SI, DI, BP, SP, are 16-bit only.

Is 8085 an 8-bit or a 16-bit microprocessor?

Although the 8085 is an 8-bit processor, it has some 16-bit operations. Any of the three 16-bit register pairs (BC, DE, HL or SP) can be loaded with an immediate 16-bit value (using LXI), incremented or decremented (using INX and DCX), or added to HL (using DAD).

Which is type of general purpose register?

The general purpose registers are divided into two categories. Four registers, AX, BX, CX, and DX, are classified as data registers.

What is difference between 8 bit and 16-bit microcontroller?

The main difference between 8 bit and 16 bit microcontrollers is the width of the data pipe. As you may have already deduced, an 8 bit microcontroller has an 8 bit data pipe while a 16 bit microcontroller has a 16 bit data pipe. … A 16 bit number gives you a lot more precision than 8 bit numbers.

Why is 4 bits called a nibble?

The term nibble originates from its representing “half a byte”, with byte a homophone of the English word bite. … An 8-bit byte is split in half and each nibble is used to store one decimal digit.

Which is bigger nibble or bit?

Binary values are often grouped into a common length of 1’s and 0’s, this number of digits is called the length of a number. … Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8-bits makes a byte.

What are 2 bits called?

2 bits: dibit, crumb, quartic digit, quad, quarter, taste, tayste, tidbit, tydbit, lick, lyck, semi-nibble, snort. 3 bits: tribit, triad, triade, tribble. 4 bits: character (on Intel 4004 – however, characters are typically 8 bits wide or larger on other processors), for others see Nibble.

What is stack example?

Therefore, a stack is referred to as a Last-In-First-Out (LIFO) list. Examples of stacks in “real life”: The stack of trays in a cafeteria; A stack of plates in a cupboard; A driveway that is only one car wide.

Why is stack pointer 16 bit?

PC and SP are utilized to store the memory locations and as the previous location address is 16-bits and so stack pointers are also of 16-bits. So that they hold a 16-bit data address.

What is main stack pointer?

Main Stack Pointer (MSP) is the default stack pointer. It is used in the Thread mode when the CONTROL bit[1] (SPSEL) is 0, and it is always used in Handler mode. … Stack operations like PUSH and POP instructions, and most instructions that use SP (R13) use the currently selected stack pointer.
