Which of the followings is/are true about RISC (Reduced instruction set computing)? a. RISC (Reduced instruction set computing) architecture has a set of instructions, so high-level language compilers can produce more efficient code
b. It allows freedom of using the space on microprocessors because of its simplicity.
c. Many RISC processors use the registers for passing arguments and holding the local variables.
d. RISC functions use only a few parameters, and the RISC processors cannot use the call instructions, and therefore, use a fixed length instruction which is easy to pipeline.
e. All of the above.

e. All of the above.

Explanation:

An instruction set architecture (ISA) can be defined as series of native memory architecture, instructions, addressing modes, external input and output devices, virtual memory, and interrupts that are meant to be executed by the directly.

Basically, this set of native data type specifies a well-defined interface for the development of the hardware and the software platform to run it.

The two (2) main types of architectural design for the central processing unit (CPU) are;

I. Complex instruction set computing (CISC): it allows multi-step operation or addressing modes to be executed within an instruction set. Thus, many low-level operations are being performed by an instruction.

II. Reduced instruction set computing (RISC): it allows fixed length instructions and simple addressing modes that can be executed within a clock cycle.

All of the following statements are true about RISC (Reduced instruction set computing) because they are its advantages over complex instruction set computing (CISC);

a. RISC (Reduced instruction set computing) architecture has a set of instructions, so high-level language compilers can produce more efficient code.

b. It allows freedom of using the space on microprocessors because of its simplicity.

c. Many RISC processors use the registers for passing arguments and holding the local variables.

d. RISC functions use only a few parameters, and the RISC processors cannot use the call instructions, and therefore, use a fixed length instruction which is easy to pipeline.
