Cisco Systems Interview Question Bank – Part 4

Cisco Systems Interview Question Bank continued from Part 3… Q : What is the function of ALE in 8085? A : ALE stands for Address Latch Enable. In 8085 microprocessor, there are 16 address lines for 16 bit memory location.…

Multiplication of 8-Bit Numbers in 8085 Microprocessor: Illustration of 3 Different Cases

8085 is a very basic microprocessor with the capability of limited arithmetic and logical operations. It has dedicated arithmetic instructions for addition, subtraction, increment and decrement. If we want to perform a multiplication operation then we need to write a…

FPGA vs. Microcontroller

FPGA stands for Field Programmable Gate Array. They are programmable integrated circuits made up of a large number configurable logic blocks (CLBs), fixed function blocks and memory blocks which can be used to perform complex digital computations. The CLBs are…

Aricent Technologies – Technical Interviews Question Bank – Part 7

Aricent Technologies Technical Interviews Question Bank continued from Part 6 Q-31. What are the different flags supported by the 8086 microprocessor? A : The 8086 microprocessor has the following flags – carry flag, auxiliary carry flag, parity flag, zero flag,…

Aricent Technologies – Technical Interviews Question Bank – Part 6

Aricent Technologies Technical Interviews Question Bank continued from Part 5 Q-26. What is the difference between microprocessor and microcontroller? A : Microprocessor is an integrated circuit that only has processor (i.e. CPU – Central Processing Unit) inside it and requires…

Different Applications of Microcontroller

Microcontroller is termed as “Computer-on-a-Chip“. It is named so, because not only the CPU, but RAM, ROM, I/O ports, Timer/Counter, Serial I/Os all are put together on a single microcontroller chip. Microcontrollers are task specific and are essentially used for…

Difference between Microprocessor & Microcontroller

When someone start dealing with Microprocessor; a very common doubt always strikes out in the initial phase: “What is the difference between Microprocessor and Microcontroller?” Let’s Define both microprocessor and microcontroller and then we will compare them. Microprocessor: We mean by…

Addition of 16-bit Numbers in 8085

This post would present you with assembly language program for 16-bit addition in 8085 microprocessor. The following Hex Code is a generic one for both no-carry and carry generation situation. // Manually store 1st 16-bit number in the memory location…

Addition of 8-bit Numbers in 8085

This post would present you with assembly language program for 8-bit addition in 8085 microprocessor. We will consider 2 different cases of addition (i) Addition of two 8-bit numbers generating no carry (ii) Addition of two 8-bit numbers generating a carry Addition…
