Boons and banes-registers in a microprocessor

Question

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

Answer 1

• When there are more common reason registers the program writing procedure is more convenient and flexible.
• The number of bits that would be necessitated to detect the registers would rise with more registers, these results in the lowering of the numeral of operations.
• When a program would engage CALL subroutines the status of the registers would have to be restored and saved frequently, this would result in an important overhead for the processor.
• Higher the numeral of these registers mores space would be employed by them on the chip. This can make problems in adding or implementing other functions on the chip.
