Let us consider a memory that includes two instructions. First instruction is located at memors address 045 that includes an address mode bit 0, an operation code 101, an address 160. The second instruction is located at the end of a subroutine that includes an address mode bit 1, a operation code 100, an address 160. The subroutine starts at memory location 161 and the conten of PC is equal to 046. a) Draw two block diagrams of the memory to represent the status of the above instruction before and after execution phase; b) List the instructions mentioned above and state the relationship between them.
