What is 80×86 microprocessor?
8086 Microprocessor is an enhanced version of 8085Microprocessor that was designed by Intel in 1976. It is a 16-bit Microprocessor having 20 address lines and16 data lines that provides up to 1MB storage. It consists of powerful instruction set, which provides operations like multiplication and division easily.
What are the microprocessor families?
A microprocessor family or a CPU family (also microcontroller family) is a group of microprocessors, microcontrollers, or component chips that make up one, developed by a specific manufacturer that share the same general architecture and feature set.
What is the model of the oldest microprocessor in the x86 family?
1971: Intel launches the world’s first microprocessor, the 4-bit 4004, designed by Federico Faggin.
What are the 16 bit families of Intel?
Intel 8086/Intel 8088.
What is Protected Mode in Intel 8086 microprocessor explain?
Virtual 8086 mode: Intel terms protected mode as virtual mode, which permits previously written code for 8086 to run on new systems (backward compatibility) without any modification, providing system stability and security. Segment addressing: In protected mode, the segment part is replaced by a 16-bit selector.
What is the microprocessor generation?
The first generation microprocessors were introduced in the year 1971-1972 by Intel Corporation. It was named Intel 4004 since it was a 4-bit processor. It was a processor on a single chip. It could perform simple arithmetic and logical operations such as addition, subtraction, Boolean OR and Boolean AND.
What are different types of microprocessors?
There are three types of microprocessors namely, CISC, RISC, and EPIC.
How many instructions are there in 8086 microprocessor?
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.
