CPU EXICUTION UNIT

MICRO PROCESSOR    

CONTROL UNIT 

Con troll of the function of CPU it tells to other parts of the CPU, how to operate what data use and where to put the results

PROTECTION TEST UNIT (PTU)

This is a part of CPU work with control unit to monitor whether or not function are carried out correctly .If it detect something is not done properly it generate and show error signal

ARITHEMETICAL LOGICAL UNIT (ALU)

ALU performs all of the calculations and logic functions for the CPU including add Subtract, Divide, Multiply, Equal to Greater than and less than and other arithmetic and logical operations

FLOTING POINT UNIOT (FPU)

It is also known as math procerssor.If handles all floating point unit operations for the ALU and the control unit floating point operations involved arithmetic on numbers with decimal releases high math operations like Trigonometry and Logarithm.

MEMMORY MANAGEMENT UNIT (MMU

The MMU handle the addressing and cataloging where the data stored in system memory. Whenever CPU need some something from memory it request it from memory

.

BUS INTERFACE UNIT (BIU)

BIU supervises the transfer data over the bus system between the other component of memory and the CPU to look ahead future instruction

PREFETCH UNIT (PU)

This unit prefetchs (preloads) the instructions from system. This allows CPU to look ahead at future instruction.

DECODE UNIT (du)

Many instructions are actually combination of simpler

Instructions the decode units decodes incoming instructions their simplest form.
