CALL instruction takes 4 bytes while RCALL takes 2 bytes.Group of answer choicesTrueFalse

Analysis of Instructions

1. Definition of CALL Instruction: The CALL instruction is used to call a subroutine, typically in assembly language or machine-level programming. It pushes the return address onto the stack and transfers control to the subroutine.

2. Definition of RCALL Instruction: The RCALL (Relative CALL) instruction is similar to CALL but is used to call a subroutine at a relative address. This is often more memory-efficient because it uses a shorter address format.

3. Size Comparison:

   • CALL instruction typically uses 4 bytes to accommodate the address size required for the full program memory space.
   • RCALL instruction uses 2 bytes since it only needs to specify a relative address, which is shorter than an absolute address.

Conclusion

Given the common characteristics of these instructions, the statement that "CALL instruction takes 4 bytes while RCALL takes 2 bytes" is indeed True.
