Functioning of registers: at any instance of time global registers and only one window of registers is visible and is addressable as if it were only set of registers. So for programming purpose there can be only 32 registers. Window in the above illustration though has a total of 138 registers. This window comprises:
However what is the maximum function calls nesting can be permitted through RISC? Let's elaborate it with the help of a circular buffer diagram technically registers as above have to be circular in the call return hierarchy.
This organization is displayed in the following figure. The register buffer is filled as function Aknown as function B, function B known as function C, function C known as function D. The function D is current function. Current window pointer (CWP) points to register window of the most recent function (function D in this case). Any register references by a machine instruction is added with contents of this pointer to decide the actual physical registers. Instead the saved window pointer recognizes the window most recently saved in memory. This action will be required if a further call is made and there is no space for that call. If function D now calls function E arguments for function E are placed in D's temporary registers denoted by D temp and CWP is advanced by one window.

If function E now makes a call to function F, the call can't be made with current status of buffer unless we free space equivalent to precisely one window. This circumstance can easily be determined as current window pointer on incrementing will be equivalent to saved window pointer. Now we need to create space; how can we do it? The simplest way would be to swap FA register to memory and use that space. So an N window register file can support N -1 level of function calls.
So the register file arranged in the form as above is a small fast register buffer which holds most of the variables which are likely to be used heavily. From this point of view register file acts nearlyas a cache memory.
