These instructions carry outlogical and arithmetic operations on data.
Arithmetic: The four fundamental operations are SUB, ADD,MUL and DIV. An arithmetic instruction may operate on fixed-point data, decimal or binary data etc. The other likely operations involve a range of single-operand instructions for illustration ABSOLUTE, NEGATE, INCREMENT, DECREMENT.
Execution of arithmetic instructions requires bringing in the operands in operational registers so that data can be processed by ALU. This type of functionality is implemented usually within instruction execution steps.
Define Program Counter(PC) The Program Counter holds the address of the next instruction to be read from memory after the current instruction is implemented.
