The microprocessor is the heart of a microcomputer system. In fact, it forms the central processing unit of any microcomputer and has been rightly referred to as the computer on a chip. This chapter gives an introduction to microprocessor fundamentals, followed by application-relevant information, such as salient features, pin configuration, internal architecture, instruction set, etc., [...]

In an ideal Digital to analog converter, the analogue output should increase by an identical step size for every one-LSB increment in the digital input word. When the input of such a converter is fed from the output of a counter, the converter output will be a perfect staircase waveform, as shown in Fig. 64.1. [...]

Digital-to-analogue (D/A) and analogue-to-digital (A/D) converters constitute an essential link when digital devices interface with analogue devices, and vice versa. They are important building blocks of any digital system, including both communication and non communication systems, besides having other applications. A Digital-to-analogue converter is important not only because it is needed at the output of [...]

A decade counter is one that goes through 10 unique output combinations and then resets as the clock proceeds further. Since it is an MOD-10 counter, it can be constructed with a minimum of four flip-flops. A four-bit counter would have 16 states. By skipping any of the six states by using some kind of [...]

In a synchronous counter,also known as a parallel counter, all the flip-flops in the counter change state at the same time in synchronism with the input clock signal. The clock signal in this case is simultaneously applied to the clock inputs of all the flip-flops. The delay involved in this case is equal to the [...]

The ink was barely dry on the fast Ethernet standard when the 802 committee began working on a yet faster Ethernet (1995). It was quickly dubbed gigabit Ethernet and was ratified by IEEE in 1998 under the name 802.3z. This identifier suggests that gigabit Ethernet is going to be the end of the line unless [...]
