Give the Schematic of Interpretation of HLL program and execution of a machine language program by the CPU.

The CPU utilizes a program counter (PC) to notice the address of next instruction to be executed.

Such instruction is subjected to the instruction execution cycle having the subsequent steps:
1. Fetch the given instruction.
2. Decode the instruction to find out the operation to be performed, and also operands of this.
3. Execute that instruction.
In the end of the cycle, the instruction address in program counter is updated and the cycle is repeated for the subsequent instruction. Program interpretation can proceed in a same manner.  The  program counter can  indicate  that  statement  of  the  source  program  is  to  be interpreted subsequently. This statement would be subjected to the interpretation cycle that consists of the given steps:
1.  Fetch the statement.
2. Analyze the statement and find out its meaning, as namely. The computation to be performed and its operands
3.  Execute the statement meaning.
