Which one of the following is a special characteristic of RISC processor?

Option 4 : Overlapped register window

RISC means Reduced Instruction Set as the acronym says aims to reduce the execution times of instructions by simplifying the instructions.

The major characteristics of RISC are as follows:

• Compared to normal instructions they have a lower number of instructions.
• The addressing modes in the case of RISC are also lower.
• All the operations that are required to be performed take place within the CPU.
• All instructions are executed in a single cycle and hence have a faster execution time.
• The characteristic of some RISC CPUs is to use an overlapped register window that provides the passing of parameters to called procedure and stores the result to the calling procedure.
• In this architecture, the processors have a large number of registers and a much more efficient instruction pipeline.
• Also, the instruction formats are of fixed length and can be easily decoded.
