What are the boons and banes of having more general purpose registers in a microprocessor.

- If there are more general purpose registers the program writing process is more flexible and convenient.

- The number of bits that would be required to detect the registers would increase with more registers, this results in the lowering of the number of operations.

- When a program would involve CALL subroutines the status of the registers would have to be saved and restored often, this would result in a significant overhead for the processor.

- Higher the number of these registers mores space would be used by them on the chip. This can create problems in adding / implementing other functions on the chip.
