A RISC machine has 62 registers out of which 8 registers are reserved for the Global variables and 24 for Instruction relatedtasks.

A RISC machine has 62 registers out of which 8 registers are reserved for  the Global variables and 24 for Instruction relatedtasks. 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.
