Described the characteristics of the RISC architecture?
Answer:
RISC meaning reduced instruction set as the acronym say 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 case of RISC is also lower.
★ All the operations that are required to be performed take place within the CPU.
★ All instruction are executed in a single cycle hence have a faster execution time.
★ 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.
