Terms in this set (4)
responsible for controlling much of the operation of the rest of the processor. it does this by issuing control signals to the other areas of the processor, instructing them on what should performed next.
used to decode instructions that make up a program when they are being processed, and to determine what actions must be taken in order to process them. These decisions are normally taken by looking at the op-code of the instruction, together with the addressing mode used.
Timer or Clock
ensures that all processes and instructions are carried out and completed at the right time. pulses are sent to the other areas of the CPU at regular intervals , actions only occur when a pulse is detected to ensure the actions all occur at regular intervals so the operations of the CPU are synchronized.
Control logic circuts
These are used to create the control signals themselves, which are then sent around the processor. these signals inform the ALU and the register array what actions and steps they should be performing and what data they should be using to perform said actions, and then what should be done with the results.
