Is 8086 an 8-bit or a 16-bit microprocessor?

Size − 8085 is 8-bit microprocessor, whereas 8086 is 16-bit microprocessor. Address Bus − 8085 has 16-bit address bus while 8086 has 20-bit address bus. Memory − 8085 can access up to 64Kb, whereas 8086 can access up to 1 Mb of memory.

What is the size of word in 8086?

Question: The word length of the 8086 microprocessor is 8 bits. A bus is a set of conducts. The 8086 microprocessors has 24 address lines.

What is the memory size in 8086?

The 8086 was designed to address as much as 1MB of memory. Normally, a 16-bit processor is limited to 64KB of RAM; while the 8086’s 20-bit bus made 1MB possible, it still needed a way to address it with a 16-bit processor.

What is the word length of an 8-bit microprocessor?

Commonly index registers are 8-bit (while other “8-bit” CPUs, such as Motorola 6800 had 16-bit index registers), such as the 6502 CPU, and then the size of the arrays addressed using indexed addressing instructions are at most 256 bytes, without needing longer code, i.e. meaning 8-bit addressing to each individual …

What do you mean by 8-bit microprocessor?

8 bit microprocessor:- 8-bit is an early computer hardware device or software program that is capable of transferring eight bits of data at the same time. The Intel 8085 is an 8-bit microprocessor. Its data bus is 8-bit wide and hence, 8 bits of data can be transmitted in parallel from or to the microprocessor.

How many bits is a word in 8086?

16-bit
The 8086 has 64 K of 8-bit (or alternatively 32 K of 16-bit word) I/O port space.

What is an 8-bit word?

A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits).

What is word size microprocessor?

Word “size” refers to the amount of data a CPU’s internal data registers can hold and process at one time. Modern desktop computers have 64-bit words. The 16-bit computer requires additional steps (16 bits first, then the remaining 8), whereas all 24 bits of the number can fit in the 32-bit register.

What is a group of 8 bits usually called?

byte
8 bits: octet, commonly also called byte.
