The Control Unit acts as master equipment by issuing control signals, while executive equipment performs operations only when commanded

The ALU controls instruction sequencing because it performs computations according to the type of arithmetic or logical operation to be executed

Master and executive equipment differ only in physical location

Memory qualifies as master equipment because it stores programs

Because arithmetic instructions are longer and have different addressing modes

Because arithmetic instructions are privileged

Because memory access is slower than arithmetic operations at registry level

Because arithmetic requires operand setup, ALU computation, and flag updates

Opcode Decoder

The Central Processing Unit including the CU and ALU

The Microprogramming Automaton (MPA)

Program Counter

The number of machine cycles required by the instruction

The number of T-states (T0 up to T5 in a hardwired implementation) used by the ALU

Instruction length in bytes

Clock frequency alone
