In this section we will see how ADC (Analog to Digital Converter) works with Intel 8085 Microprocessor. The Analog to Digital Conversion is a quantizing process. Here the analog signal is represented by equivalent binary states. The A/D converters can be classified into two groups based on their conversion techniques.In the first technique it compares given analog signal with the initially generated equivalent signal. In this technique, it includes successive approximation, counter and flash type converters. In another technique it determines the changing of analog signals into time or frequency. This process includes integrator-converters and voltage-to-frequency converters. The first process ... Read More

A Microcontroller is a small and low-cost microcomputer, which is designed to perform the specific tasks of embedded systems like displaying microwave’s information, receiving remote signals etc.The general microcontroller consists of the processor, the memory (RAM, ROM, EPROM), Serial ports, peripherals (timers, counters) etc.Types of MicrocontrollersMicrocontrollers are divided into various categories based on memory, architecture, bits and instruction sets. Following is the list of their typesBit − Based on bit configuration, the microcontroller is further divided into three categories.8-bit microcontroller − This type of microcontroller is used to execute arithmetic and logical operations like addition, subtraction, multiplication division, etc. For example, ...

In computer architecture, 32-bit integers, memory addresses, or other data units are those that are 32 bits (4 octets or 4 Bytes) wide. Also, 32-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 32-bit microcomputers are computers in which 32-bit microprocessors are the norm. We know that n-bit microprocessor can handle n-bit word size.As n-bit register can store 2n different values so, a 32-bit register can store 232 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. We ... Read More

In computer architecture, 16-bit integers, memory addresses, or other data units are those that are 16 bits (2 octets or 2 Bytes) wide. Also, 16-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 16-bit microcomputers are computers in which 16-bit microprocessors were the norm.As n-bit register can store 2n different values. So as a result, 16-bit register can store 216 different values. If we consider the signed range of integer values that can be stored in 16 bits is −32, 768 (−1 × 215) through 32, 767 (215 − ...

In computer architecture, 8-bit integers, memory addresses, or other data units are those that are 8 bits (1 octet or 1 Byte) wide. Also, 8-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 8-bit is also a generation of microcomputers in which 8-bit microprocessors were the norm. Mainly we can consider 8-bit microprocessor means 8-bit data or information bus.for controlling a CRT display, Federico Faggin and his team at Intel designed a chip produced by Computer Terminals Corporation. Later this chip was called as Datapoint. This chip did not ... Read More

In the 4-bit microprocessor or computer architecture will have a data path width or a highest operand width of 4 bits or a nibble. And also these architectures or microprocessors typically will have a matching register file with registers width of 4 bits and 4-8-bit wide addresses.Most of the first microprocessors during the early 1970s had 4-bit word sizes. Both the Intel 4004, the first commercial microprocessor, and the 4040 had a 4-bit word length, but had 8-bit instructions. Some of the first microcontrollers such as the TMS1000 made by Texas Instruments and NEC's μPD751 also had 4-bit words. 4-bit ... Read More

An electronic circuit is a group of electronic components connected for a specific purpose.A simple electronic circuit can be designed easily because it requires few discrete electronic components and connections. However, designing a complex electronic circuit is difficult, as it requires a number of discrete electronic components and their connections. It is also time taking to build such complex circuits and their reliability is also less. These difficulties can be overcome with Integrated Circuits.To define Integrated Circuit (IC) we can consider that If multiple electronic components are interconnected on a single chip of semiconductor material, then that chip is called ...
