Question

A partial data path of a processor is given in the figure, where RA, RB, and RZ are 32-bit registers. Which option(s) is/are CORRECT related to arithmetic operations using the data path as shown? 

 

• A. The data path can implement arithmetic operations involving two registers.
• B. The data path can implement arithmetic operations involving one register and one immediate value.
• C. The data path can implement arithmetic operations involving two immediate values.
• D. The data path can only implement arithmetic operations involving one register and one immediate value.

Hint:

In processor data paths, multiplexers are used to select between different inputs for operations such as addition or subtraction, involving registers or immediate values.

Answer 1

The Correct Option is A, B, C

The data path can perform arithmetic operations involving two registers, as both \(RA\) and \(RB\) are connected to the ALU.
The data path can also perform arithmetic operations involving one register and one immediate value, as the multiplexers allow immediate values to be selected.
The data path can implement arithmetic operations involving two immediate values, as both \(Mux_A\) and \(Mux_B\) allow immediate values to be passed to the ALU. Thus, the correct answers are \( \boxed{A} \), \( \boxed{B} \), and \( \boxed{C} \).
