Flags Flags are flip-flops that store bit 0 or 1 based on the arithmetic or logical operation performed by an arithmetic and logical unit (ALU). In most of the operations, the result is stored in the accumulator. There are five flags present in 8085 microprocessor. All the flags are present in an 8-bit register called as status … Read more
The phototransistor is a semiconductor light sensor formed from a basic transistor with a transparent cover that provides much better sensitivity than a photodiode. It is basically a 3-layer semiconductor device which has a light-sensitive base region. The base senses the light and converts it into the current which flows between the collector and the … Read more
When an alternating potential difference between the two conductors of a transmission line is raised beyond a certain limit, a point is reached when a pale violet glow appears on the conductor surface, together with a hissing noise. This phenomenon is known as Corona. Actually, air particles around the conductor surface get ionised and as … Read more
8086 microprocessor has two units; Execution Unit (EU) and Bus Interface Unit (BIU). They are dependent and get worked by each other. Below is a short description of these two units. Execution Unit (EU) Execution unit receives program instruction codes and data from the BIU, executes them and stores the results in the general registers. … Read more
A flowchart is a program designing tool which is designed to show the processing logic of any program. It is a pictorial representation so it can be drawn on the paper only. It is free from any particular programming language. The processing logic shown by flowchart can be implemented in any programming language. The symbols … Read more

Microprocessor Definition A microprocessor is a multi-purpose, Programmable, clock driven, register-based electronic device that reads binary instructions from a storage device called memory, accepts binary data as input and processes data according to those instructions and provide results as output. OR It is an electronic device that fetches instructions from memory, execute them and provide … Read more
In this article, we will discuss the Difference between 8085 and 8086 Microprocessor. 8085 Microprocessor 8086 Microprocessor Size 8085 is an 8-bit microprocessor. 16-bit microprocessor Address Bus 8085 has 16-bit address bus 8086 has 20-bit address bus Memory 8085 can access upto 216 = 64 Kb of memory. 8086 can access upto 220 = 1 MB of … Read more
Transfer function Definition A transfer function is expressed as the ratio of Laplace transform of output to the Laplace transform of input assuming all initial condition to be zero. Consider a system whose time domain block diagram is where, r(t) = input and c(t) = output Now taking Laplace transform then Now the transfer … Read more
