# Registers

Introduction We are all familiar with the word “register”, yes, the same which we use in our schools days. That register is a place we write our day-to-day notes, and these notes get stored permanently in this register. So we define such register as a group of pages used to store characters. This register come in various size, the total capacity in terms of number of characters is calculated as: Capacity = (number of pages) x (number of lines) x (number of characters per line) Register: In computers also information is stored in registers. A register is a collection of storage elements that are used to store or process the binary information. The memory elements used are the flip-flops. Types of registers: a) The storage registers: The

# Sequential Circuit

Introduction In the previous posts we have focused on the design of many combinational circuits. The outputs in those circuits were dependent on the inputs applied at that instant of taking the output. Examples of such circuits were adders like half and full adders, half and full subtractors, BCD adders, Multiplexers, decoders , etc. But what if we have to add say 5, 10 or even more numbers. Practically we only two numbers at a time, store the partial result in our memory and then add this partial result(memory content) with the next numbers to get next partial sum and so on till all the numbers have been added. To save the partial results we need memory device. Such types of circuits

# Design of Counters

Introduction to Counters I remember my childhood, at a time even before going to the primary school, we used to play with pebbles, soon we started counting the pebbles. When I joined school, I realized that counting is part of our life and is used in every walk of life, count starting from zero, or starting from any number (preset). As I grew, I found counting used for different purpose; we go to refuel our vehicle, there a meter that counts the amount and the quantity of fuel; counting the marks awarded to student in an exam; days temperature, population of a city/ country, counting the score in a match, number of votes obtained by a candidate in an election, number
