All signal of processor

Control Signal of Processor-  Control signal are electronic signals that orchestrate the various processor units participating in the execution of an instruction.  Central signals are sent using an element called a sequenced. For example read and write signal allows the memory to be told that the processor wants to read and write information.
Function Unit of Processor-  The processor the madeup of the group to interrelated units (or control  unit) Microprocessor architecture varies considerably from one design to another but the main elements of a microprocessor are as fallows.
                    A control unit that links the incoming data, decodes it, and sends it to the execution unit, the central unit is made up of the following elements.
Sequencer of Processor (or monitor and Logical Unit)-  That synchronize instruction execution with the clock speed .  It also sends control signals.
An execution Unit(or processing unit)-  That accomplish tasks assigned to it by the instructions unit.  The execution unit is made of the following elements.
The arithmetical and logical unit (written ALU).  The ALU perform basic arithmetical calculation and logic functions (And or Exclusive or etc).
The floating point unit (written FPU) that performs partial complex calculations which cannot be done by the arithmetical and logic unit.
Bus Management Unit-  That manage the flow of incoming and outgoing information and that interfaces with system RAM.
