A RISC machine has 62 registers out of which 8 registers are reserved for the Global variables and 24 for Instruction related tasks. This machine has been designed to have 6 registers for storing two input parameters, two output parameters and two local variables for function call. Explain with the help of a diagram, how the overlapped register window can be implemented in this machine for function/procedure calls. You must explain how the parameters will be passed when a function calls another function.

Write and run an Assembly language program that converts an ASCII string containing decimal digits, stored in three consecutive locations in the memory into equivalent binary number. You may assume that the three locations contains ASCII equivalent of digit 3, digit 4 and digit 5. The output of this program should be stored in AX register.

Design a two bit counter circuit that counts from 0 to 2 only, that is, it will have states 00, 01, 10 only. The initial state of the counter may be assumed to be 00. The counter will be in following successive states: 00, 01, 10, 00, 01, 10, 00, 01, 10, 00 ... Use any flip flop to design the circuit. You must design them using state transition diagram and Karnaugh's map.
