The 8086 is the first 16-bit processor developed by Intel. The 8086 microprocessor, which was introduced in 1978 and was widely used in personal computers (PCs), uses VLSI technology. With a structure width of 3 µm, 29,000 transistors were integrated on the chip.
The 8086 is clocked at 4.77, 8, 9.54 and 10 MHz and has an address bus of 20 bits, which can be used to address memories of up to 1 megabyte (MB). Its computing power is 0.75 MIPS. It is housed in a 40-pin dual-inline package.
The instruction set of the 8086 includes transfer instructions, shift instructions, jump instructions, iterations, control instructions, and input and output instructions.
