Let's Program the Transistors
Verilog language has the capability of designing a module in several coding styles. Depending on the needs of a design, internals of each module can be defined at four level of abstractions. Irrespective of the internal abstraction level, the module would behave exactly in the similar way to the external environment. Following are the four…

Do you love to play with FPGAs? If yes, then there is a golden opportunity to showcase your talent. Digilent Design Contest Europe Region has reached its 12th Edition, with a rich history behind, many interesting and cool projects along the years, many smart and competitive participants, as well as appreciated advisers. It is held in Cluj-Napoca, Romania,…
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 figure) to design the circuit. Pin Input / Output Description D Input Data Input CLK…

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 making Embedded Systems. The above image shows very few examples for the application of microcontrollers…
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 a microprocessor that all the components of a CPU (Central Processing Unit): ALU (Arithmetic Logic…

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 2000H & 2001H in reverse order // For Example 1st number = B349H; i.e, 2000<-49H…
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 of two 8-bit numbers generating no carry // Manually store 1st number in the memory…
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. A basic CMOS structure of any 2-input logic gate can be drawn as follows: 2…
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) Access Type (ii) Data Retention Capability Note: Hard-Disk, CD, DVD, Floppy-Disk, Magnetic Tape are also…
