What is a 16-bit microprocessor?

Microprocessor8085Microcontroller. In computer architecture, 16-bit integers, memory addresses, or other data units are those that are 16 bits (2 octets or 2 Bytes) wide. Also, 16-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

What features of a microprocessor?

Features of Microprocessor Low Cost – Due to integrated circuit technology microprocessors are available at very low cost. It will reduce the cost of a computer system. High Speed – Due to the technology involved in it, the microprocessor can work at very high speed. It can execute millions of instructions per second.

Which of these are 16-bit microprocessors?

Other notable 16-bit processors include the Intel 8086, the Intel 80286, the WDC 65C816, and the Zilog Z8000.

What are the advantages of 16-bit microprocessor over 8-bit microprocessor?

At one time, the 16-bit processor had a clear performance and memory advantage over eight-bit CPUs. The wider bit-width of the 16-bit machine meant that in a single cycle, a 16-bit machine could do more work than an eight-bit machine in that same cycle.

What is the difference between 8-bit and 16-bit microprocessor?

A 8-bit microprocessor can perform 1 Byte(8 bit) of data operation in one machine cycle. In case of 16-bit microprocessor 2 Bytes of data gets operated in one machine cycle. Processing and operation capability of 16 bit microprocessor will twice greater than 8-bit microprocessor.

What are the main features of 8085 microprocessor?

The features of 8085 include:

• It is an 8-bit microprocessor i.e. it can accept, process or provide 8-bit data.
• It operates on a single +5V power supply connected at Vcc.
• It operates on clock cycle with 50% duly cycle.
• It has on chip clock generator this internal clock generator requires tuned circuit like LC,

What are the features of8086 microprocessor?

Features of 8086 It was the first 16-bit processor having 16-bit ALU, 16-bit registers, internal data bus, and 16-bit external data bus resulting in faster processing. It uses two stages of pipelining, i.e. Fetch Stage and Execute Stage, which improves performance.

Which is the first 16-bit microprocessor?

Intel 8086
The 8086 (also called iAPX 86) is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released.

What are the advantages and disadvantages of a 16-bit microprocessor compared with a 32-bit microprocessor?

While a 16-bit processor can simulate 32-bit arithmetic using double-precision operands, 32-bit processors are much more efficient. While 16-bit processors can use segment registers to access more than 64K elements of memory, this technique becomes awkward and slow if it must be used frequently.

What are the differences between 8-bit and 16-bit microprocessor?

What is meant by a 16 bit microprocessor?

16-Bit. Refers to the number of bits that can be processed or transmitted in parallel, or the number of bits used for single element in a data format. The term is often applied to the following: microprocessor: indicates the width of the registers. A 16-bit microprocessor can process data and memory addresses that are represented by 16 bits.

What is different between 16 bit and 32 bit microcontroller?

– Processor core – NVIC (Nested Vector Interrupt Controller) – Debug system – Bus system and bus matrix – Memory – Peripheral

Why is 8086 microprocessor is of 16 bit?

There are also four 16-bit segment registers (see figure) that allow the 8086 CPU to access one megabyte of memory in an unusual way. Rather than concatenating the segment register with the address register, as in most processors whose address space exceeds their register size, the 8086 shifts the 16-bit segment only four bits left before adding it to the 16-bit offset (16×segment + offset), therefore producing a 20-bit external (or effective or physical) address from the 32-bit segment

Why is Intel 8086 known as 16 bit microprocessor?

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.
