Question

Consider a 16-bit processor in which the following appears in the main memory, starting at location 200.
a. The first part of the first word (content at 200) indicates that this instruction loads a value into an accumulator; the value of 300 in location 201 may be part of the address calculator. The mode field specifies an addressing mode and, if appropriate, indicates a source register. 
a.  Assume that when used, the source register R1, which has a value of 500. 
b.  There is also a base register that contains the value 100, 
Assume that location 249 contains the value 399, location 250 contains the value 400, and so on.  Determine  the  effective  address  and  the  operand  to  be  loaded  for  the following  address modes:
