2 bit Multiplier

A Binary Multiplier is a digital circuit used in digital electronics to multiply two binary numbers and provide the result as output. The method used to multiply two binary numbers is similar to the method taught to school children for multiplying decimal numbers which is based on calculating partial product, shifting them and adding them together. Similar approach is used to multiply two binary numbers. Long multiplicand is multiplied by 0 or 1 which is much easier than decimal multiplication as product by 0 or 1 is 0 or same number respectively. Figure 1 below shows the block diagram of a 2-bit binary multiplier. The two numbers A1A0 and B1B0 are multiplied together to produce a 4-bit output P3P2P1P0.

Frequency Divider

  Frequency Divider It called as Clock divider That circuit  takes an input signal of a  frequency  and generates an output signal of a frequency Frequency  is the number of occurrences of a repeating event per  unit of time Create Frequency divider using JK Flip Flops  A frequency divider can be constructed from J-K flip-flops by taking the output of one cell to the clock input of the next. The J and K inputs of each flip-flop are set to 1 to produce a toggle at each cycle of the clock input. For each two toggles of the first cell, a toggle is produced in the second cell, so its output is at half the frequency of the first. The output of the fourth cell is 1/16 the clock frequency. The same device is useful as a binary counte r Create & Simulate

Register Memory

 Register Memory Register memory is the smallest and fastest memory o n your computer. It is not part of main memory , but is located o n the CPU in the form of registers, which are the smallest data holding elements. R egister s temporarily s tore frequently used data, co mma n d s, and memory addresse s used by the CPU. H olds the command currently being processed from the CPU. All data m u s t pass through registers before it can be processed. Theref o re , i t is used to process the data entered by the user from the CPU . The r egister hold s a small amount of data , a b ou t 32 to 64 bits. The speed of the CPU depends on the number and size (n umber of bits) of the registers built into the CPU. Registers can be of va r ious types d e pen d ing on the application. W idely used r egisters include a ccumulator s or AC s , d ata r egisters and DRs, address registers or ARs, program count e rs (PCs), and I / O address registers . Types and Functi
