Circuit Design of a 4-bit Binary Counter Using D Flip-flops
Problem Statement: Design a circuit for an edge triggered 4-bit binary up counter (0000 to 1111). When it reaches “1111”, it should revert back to “0000” after the next edge. Use positive edge triggered D flip-flop (shown in the below…
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…
NAND and NOR gate using CMOS Technology
For the design of any circuit with the CMOS technology; We need parallel or series connections of nMOS and pMOS with a nMOS source tied directly or indirectly to ground and a pMOS source tied directly or indirectly to Vdd.…
Classification of Semiconductor Memories and Computer Memories
Memory devices are something which retain data for a time period just like human brain. This post classifies the Semiconductor Memories and maps different memory devices to Computer Memories. Semiconductor Memories Semiconductor Memories can be classified based on two different characteristics: (i)…
