Chapter 6, Problem 2CRP

Converting python program x=0 while (x<3): x=x+1 into machine language:

Below table shows the machine language coding translated for python programming given above:

Address (Hexadecimal)	Machine code	Comments for each given instructions
01	2000	#load value 00 to the register 0
02	2101	#load value 01 to the register 1
03	2200	#load value 00 to the register 2
04	2303	#Load value 03 to the register 3
05	B309	#if the bits in register 3 and register 0 are equal then jump to memory cell address 08. If not then continue the execution further.
06	5221	#store the resulting value of contents into register 2 by adding register 2 and register 1 contents
07	4020	#move contents (means copy the contents) of register 2 to register 0
08	B205	#if bits in register 0 and register 2 are same then jump to memory cell address 05
09	C000	#halt the program

Considering the above machine coding following describes briefly about the programming:

• Consider the instruction code 2000:

  Here 2 represent the opcode for LOAD operation which is to be performed. This instruction will load the value 00 into register 0.

• Consider the instruction code 2101:

  Here 2 represent the opcode for LOAD operation. This instruction will load value 01 into the register 1.

• Consider the instruction code 2200:

  Here 2 represent the opcode for LOAD operation...
