Binary is a base-2 number system that uses two states 0 and 1 to represent a number. We can also call it to be a… Read More
Latches are basic storage elements that operate with signal levels (rather than signal transitions). Latches controlled by a clock transition are flip-flops. Latches are level-sensitive… Read More
The IEEE Standard for Floating-Point Arithmetic (IEEE 754) is a technical standard for floating-point computation which was established in 1985 by the Institute of Electrical… Read More
One Bit memory cell is also called Basic Bistable element. It has two cross-coupled inverters, 2 outputs Q and Q’. It is called “Bistable” as… Read More
Memory devices are digital system that store data either temporarily or for a long term. Digital computers to hard disk have built in memory devices… Read More
The data storage and transmission elements found in digital hardware are represented using a set of Verilog Hardware Description Language (HDL) data types. The purpose… Read More
A Universal shift register is a register which has both the right shift and left shift with parallel load capabilities. Universal shift registers are used… Read More
In computer architecture 2’s Complement Number System is widely used. The discussion of overflow here mainly will we with respect to 2’s Complimentary System.  N-bit… Read More
