F
T
4. Source operand reference IS the operation may involve only one source operands, that is, operands that are inputs for the operation.
T
F
Result operand reference is the operation may produce a result
T
F
Next instruction reference this tells the processor where to fetch the next instruction after the execution of this instruction is complete
T
F
Main or virtual memory as with next instruction references, the main or virtual memory address mustn’t be supplied.
T
F
immediate is the value of the operand is contained in a field in the instruction being executed
T
F
I/O device is the instruction mustn’t specify the I/O module and device for the operation.
T
F
The instruction set defines many of the functions performed by the processor and thus has a significant effect on the implementation of the processor
T
F
Types of operands that is Machine instructions operate on data
T
F
Fetch instruction that is the processor reads an instruction from memory
T
F
Interpret instruction that is the instruction didn’t decode to determine what action is required
T
F
Process data is the execution of an instruction may require performing some arithmetic or logical operation on data.
T
F
Write data is the results of an execution may not require writing data to memory or an I/O module
T
F
Major components of the processor are an arithmetic and logic unit (ALU) and a control unit (CU).
T
F
The control unit didn’t controls the movement of data and instructions into and out of the processor and controls the operation of the ALU
T
F
any general-purpose register can contain the operand for any opcode.
T
F
Data registers may be used only to hold data and cannot be employed in the calculation of an operand address
