Both the temporary registers as well as accumulators are utilized for holding the information throughout the operations then the outcome will be stored within the accumulator. The main operation of ALU is arithmetic as well as logical which includes addition, increment, subtraction, decrement, logical operations like AND, OR, Ex-OR, complement, evaluation, left shift or right shift. The most important part of the microprocessor is the central processing unit.Ĩ085 Architecture Operations of the 8085 Microprocessor
