Figure: A Hypothetical Instruction Format of 32 bits

Please note the subsequent points in Figure below:

Opcode size is 5 bits. So in general it will have 2⁵ = 32 operations.
There is just one operand address machine.
There are two bits for addressing modes. Hence there are 2² = 4 different addressing modes possible for this machine.
The last field (8 - 31 bits = 24 bits) here is operand or the address of operand field.

In case of immediate operand, maximum size of the unsigned operand will be 2²⁴.

In case it's an address of operand in memory then maximum physical memory size supported by this machine is 2²⁴ = 16 MB.
