Processor components
The control
unit
Part of the processor
that coordinates
the
activity of all other components
conal
Signals are sent along me
between cu, and other
control bus
components
- A bus in a computer consists of a series of
connector internal
between
Signals,
transfers

components
Systembus
inPut/outPut memds
Processo
Control bus
Data bus
address bus
, Conkol Signals include
• memoryread - causes data fom address location.
in RAm to be Placed on databus
data on databus to
• Memory write Causes
be written intore addressed location in Ram
• Clock - used to sydachronise
operations
Alu
- Problem Solving part of the Brocessor
- The Accumulator Stores the result from the Alu
Dedicated
registers
- PC - holds address of the next instruction to beexeruda
- CIR - Nolds the current instruction split into aprode and operals
- MAR - holds the address in memory to fetch data from
hads data needed to exeute inskuction
- MOR - temporarilly
- 7 ACC - holds results of calculations
