Status or Flag Register in 8085 Microprocessor

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 moreStatus or Flag Register in 8085 Microprocessor

What is Flowchart & Symbols used in flowchart?

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 moreWhat is Flowchart & Symbols used in flowchart?
