How many general purpose registers does a 16-bit processor have?

purpose
General purpose registers are used to store temporary data within the microprocessor. There are 8 general purpose registers in 8086 microprocessor.

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

The 8085 has six general-purpose registers to store 8-bit data; these are identified as- B, C, D, E, H, and L. These can be combined as register pairs – BC, DE, and HL, to perform some 16-bit operation. These registers are used to store or copy temporary data, by using instructions, during the execution of the program.

How many registers are there in microprocessor?

General-Purpose Registers: The 8085 microprocessor contains six 8-bit general purpose registers. They are: B, D, C, E, H and L register. To hold data of 16-bit a combination of two 8-bit registers can be employed. The combination of two 8-bit registers is called register pair.

Which of the following is a 16-bit code?

16-bit is a computer hardware device or software program capable of transferring 16 bits of data at a time. For example, early computer processors (e.g., 8088 and 80286) were 16-bit processors, meaning they were capable of working with 16-bit binary numbers (decimal number up to 65,535).

Which of the following are the 16-bit registers in 8051?

The accumulator, R0–R7 registers and B register are 1-byte value registers. It is used by the 8051 to access external memory using the address indicated by DPTR. DPTR is the only 16-bit register available and is often used to store 2-byte values.

How many general purpose registers are there in 8086 microprocessor?

There are 8 general purpose registers in 8086 microprocessor. Figure – General purpose registers 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.

Are 8086 addresses 20-bit or 32-bit?

Addresses are still 20-bit for both.) 8086 CPU has 8 general purpose registers, each register has its own name: AX – the accumulator register (divided into AH / AL): BX – the base address register (divided into BH / BL). CX – the count register (divided into CH / CL):

How many 16-bit general purpose registers are there in microcontroller?

Four 16-bit segment registers which are ES, SS, DS and CS. (Extra segment, Stack Segment, Data Segment and Code Segment) They hold the upper 16 bits a Four 16-bit general purpose registers. (AX, BX, CX and DX) Each of these can be split into two 8-bit registers.

What is the difference between 8086 and 8088 microprocessors?

The Intel 8086/8088 were 16-bit processors with a 20-bit address bus (the 8088 had an external 8-bit data bus, but inside it was identical to the 8086). They used segmented addressing to allow these chips to address 1 MB of memory. 16-bit segment registers were used to define the base address of four regions of memory.
