What are the features of 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.
What do you know about the modes of 80186?
The mode/control register allows the 80186 to operate in two modes. These are nor-iRMX-86 and iRMX-86 modes. The non-iRMX-86 is also called the master mode.
What are the Intel’s model of microprocessors?
Microprocessors made by Intel Corporation form the foundation of all PCs. Models after the 8086 are often referred to by the last three digits (for example, the 286, 386, and 486). The 80386, for example, can run programs written for the 8086, 8088, and 80286. …
What are the features of 80486 microprocessor?

What is true about 80286 microprocessor?
80286 Microprocessor is a 16-bit microprocessor that has the ability to execute 16-bit instruction at a time. It has non-multiplexed data and address bus. The size of data bus is 16-bit whereas the size of address bus is 24-bit. The performance per clock cycle of 80286 is almost twice when compared with 8086 or 8088.
Which of the following are the features of a microprocessor Mcq?
Explanation: Microprocessor consists of an ALU, register array, and a control unit.
What are the three functions of a microprocessor?
The functions of microprocessor are given below: (a) To fetch, decode and execute instructions. (b) To transfer data from one block to another block or from one block to I/O lines. (c) To give proper response to different externally produced interrupts according to their priority.
What are the basic features of 80486?
One of the most obvious feature included in a 80486 is a built in math coprocessor. This coprocessor is essentially the same as the 80387 processor used with a 80386, but being integrated on the chip allows it to execute math instructions about three times as fast as a 80386/387 combination.
What are the differences between microprocessor 80186 and 80286 explain properly?
80186 is a 16-bit microprocessor with 16- bit data bus and 20-bit address bus. 80286 Microprocessor has Data bus width of 16, Addressed Memory size of : 16M, Clock speed is higher and hence some instructions are executed in as little as 250ns, 80286 does not have multiplexed address/data bus lines.
What is the main improvement of the 80186 microprocessor over 8086?
Multiply and divide also showed great improvement being several times as fast as on the original 8086 and multi-bit shifts were done almost four times as quickly as in the 8086.
What are the differences between 80186 80286 and 80386 explain in detail?
What is the 80186 microprocessor?
The Intel 80186, also known as the iAPX 186, or just 186, is a microprocessor and microcontroller introduced in 1982. It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus. It was also available as the 80188, with an 8-bit external data bus.
What is the difference between 80186 and 80188?
The Intel 80186, also known as the iAPX 186, or just 186, is a microprocessor and microcontroller introduced in 1982. It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus. The 80188 variant, with an 8-bit external data bus was also available.
What is the difference between 8086 and i186?
Intel 80186 microprocessor, sometimes called i186, is an enhanced version of Intel 808616-bit processor. Being completely object code compatible with the 8086, the 80186 integrated many system components into one chip, added 7 new instructions, and added new operand types to three existing 8086 instructions.
Why was the 8086 replaced by the 80286?
The 80186 would have been a natural successor to the 8086 in personal computers. However, because its integrated hardware was incompatible with the hardware used in the original IBM PC, the 80286 was used as the successor instead in the IBM PC/AT .
