Question 25 Explanation:
Hardwired Unit:
It can be optimized to produce fast modes of operations.
It uses a large number of registers and because of that it is costly.
Instruction size in the Hardwired unit is fixed.
It has a small number of addressing modes.
Indirect Addressing mode:
The address part is the binary equivalent of 300. The control goes to address 300 to find the address of the operand. The address of the operand in this case is 1350. The operand found in address 1350 is then added to the content of AC. The indirect address instruction needs two references to memory to fetch an operand. The first reference is needed to read the address of the operand; the second is for the operand itself.
