- 15. MICROPROCESS OR By : Devansh Koolwal History of 8086 Microprocessor 8086 Microprocessor is an enhanced version of 8085 Microprocessor 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. It supports two modes of operation, i.e. Maximum mode and Minimum mode. Maximum mode is suitable for system having multiple processors and Minimum mode is suitable for system having a single processor.
- 16. MICROPROCESS OR By : Devansh Koolwal History of 8086 Microprocessor ”Intel’s original goal with the 8086 was to improve overall performance relative to previous products while retaining source compatibility with earlier products (meaning assembly language for the 8008, 8080, or 8085 could be run on the 8086 after being recompiled). It offered faster overall performance than the 8080 or 8085 and could address up to 1MB of RAM (the 8085 topped out at 64KB). It contained eight 16-bit registers, which is where the x86 abbreviation comes from in the first place, and was originally offered at a clock speed of 5MHz (later versions were clocked as high as 10MHz).

- NEXT:DEVANSH Gordon Earle Moore is an American businessman, engineer, and the co-founder and chairman emeritus of Intel Corporation. He is also the author of Moore's law. As of 2018, Moore's net worth is reported to be $9.5 billion. Robert Norton Noyce, nicknamed "the Mayor of Silicon Valley," was an American physicist who co-founded Fairchild Semiconductor in 1957 and Intel Corporation in 1968.
- BIU bus interface unit Every processor have the fundamental thing that fetch – decode – execute interuction C-Bus communications protocol Memory segmentation (registers) Registers contains addressof that particular segment IP instruction pointer contains address of offset address DS - generally points at segment where variables are defined. SS - points at the segment containing the stack. CS - points at the segment containing the current program. ES - extra segment register, it's up to a coder to define its usage.
- EU- execution unit A-BUS ALUdata bus AX accumulator register BX - base address register CX - count register DX Data register SI Source index Bp base pointer Sp stack pointer DI destination index Operands are the data contents on which the operation is to be performed. 8086 has 16 bit flag register among which 9 bits are active. The purpose of theFLAGS register is to indicate the status of the processor.
- It has an instruction queue, which is capable of storing six instruction bytes from the memory resulting in faster processing. 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 has 29000 Transistors It is available in 3 versions based on the frequency of operation − 8086 → 5MHz 8086-2 → 8MHz (c)8086-1 → 10 MHz
