Control Unit in CPU
CPU contains
*Arithmetic logic unit.It handles the logical operations..I will ask some more about this in a new topic.
*Control unit-handle the flow of data between CPU & Main memory.what is this CU?how it control the data flow.?please tell me the basic architecture about this..
*Registers-Special memory area inside processor.The number of Bites which can store in a REGISTER called word size.please explain about word size....(i will read about REGISTERS & then ask questions about them future..)
Control Unit in CPU
Re: Control Unit in CPU
CU is basically responsible on handling the most important 2 buses (set of pins wired from one chip to the other which is used for communication between the chips in simple terms) connected to CPU.*Control unit-handle the flow of data between CPU & Main memory.what is this CU?how it control the data flow.?please tell me the basic architecture about this..
- Address bus
- Data bus
Memory Read
Think that we are going to write something to memory at memory address 0xE0008056. Here is the procedure.
- Write 0xE0008056 to address bus
- Read value from data bus
Say, we are going to write value 100 to memory address 0xE0008056. Here is the procedure.
- Write 0xE0008056 to address bus
- Write 100 to data bus
Word is a term for the natural unit of data used by a particular computer design. A word is simply a fixed sized group of bits that are handled together by the system. The number of bits in a word is called word size or word length and it is an important characteristic of computer architecture.*Registers-Special memory area inside processor.The number of Bites which can store in a REGISTER called word size.please explain about word size....(i will read about REGISTERS & then ask questions about them future..)
If you refer your CPU is a 32-bit one, that means you have 32-bit registers in the CPU.
Your CPU is capable of doing operations like addition, subtraction, etc... on these 32-bit registers at ones.
Some of the common CPU architectures with different word lengths are given below.
- Z80
This is the microprocessor (8-bit word length) that was in my first computer (Sinclair ZX Spectrum). 3.5 MHz speed, 48 KB RAM, no disk drive at all (need to use audio tapes with a cassette recorder). As a respect, I submitted that on top of the list. - x86 Architectures
- Texas Instruments TMS320C6400 Digital Signal Processors
- PIC microcontroller
- Atmel AVR microcontroller
- ARM architecture
Re: Control Unit in CPU
Thank you friend.now i have a clear picture on this CU read & write controls.i referred some wed to get more ideas.
My processor is "Dual core Desktop Intel Pentium processor" one.Intel 64 architecture.then this is my word size right?
Friend I have a little question.When we download software there are 32X & 64X.is This deviation according to the processor architecture?according to the my processor I should choose 64X software...But normally I get 32X software...
can you tell me what happen If any one install 64X software to a 32x computer..?
