Some architectures support the memory indirect addressing mode. Below is an example. In this case, the register R2 contains a pointer to a pointer. Two memory accesses are required to load the data.

ADD R3, @(R2)

Assume that our ISA does not support memory-indirect addressing, implement the functionality of the previous statement using other addressing modes were covered in the class. Note that you can use multiple instructions. Assume that the pointer to pointer is currently in R2, R3 holds the value to be added, and the result will be stored in R3.
