Detailed explanation-1: -Which of the following is not a Features of 8086? D. It has 512 vectored interrupts. Explanation: It has 256 vectored interrupts is true Features of 8086.
Detailed explanation-2: -8086 is featured with 16 registers, an internal and external bus, with 5MHz frequency, 256 based vector interrupts, and built with 29000 transistors. It comprises 2 main segments BIU and EU segment, where BIU segments compromise of registers and buses, and the EU segment comprises ALU and registers.
Detailed explanation-3: -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.
Detailed explanation-4: -Which of the following is correct about 8086 microprocessor? Explanation: The Intel 8086 is Intel’s first x86 processor. They launched the most powerful processor in terms of advanced architecture i.e. 8086 processor in 1978. It has larger memory addressing capability and a powerful instruction set.
Detailed explanation-5: -Which of the following instruction is not valid? Explanation: Both the source and destination operands cannot be memory locations except for string instructions.
