well, as stated on:
http://www.webopedia.com/TERM/C/CPU.html
# The control unit, which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
and just for your own knowledge, be careful how u reply to people when they post to you. There sno need to tlak to ppl like they dont know what they are talking about. Do you see that word ADMINISTRATOR under PRAETOR name? that means he rules this place. hes extremely knowledgeable and when he replys to your posts, you should probably listen to what he is asking/saying. hes only trying to clarify and help. so am i.

I've seen it more commonly as the "ALU".
"Cu" is copper in science terms, so the context in which you use the term is very important.
it could also translate to "see you" meaning "goodbye".
"Two typical components of a CPU are:
The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
The control unit, which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary."

Heh not always do we encounter people who want to jump deep into computer architecture. Anyways you correct in that the control unit is very critical in controlling the processor's actions: it determines exactly whether or not a bitshift will occur on a given clock pulse or not!
- Suppose we have a simple 4bit shift register as here consisting entirely of DFFs. On the left we have a SI and on the right we have a SO which correspond to the serial inputs and outputs which happen during each shift
- Now suppose we want to control the shifting and not have it occur during every clock cycle (i.e., for synchronizing).
- The simplest way to implement this is to introduce a control unit in parallel with the clock as inputs to a AND2 unit.
- An implementation of a controlled serial transfer with two 4bit shift registers is shown below. The reason there is a loopback circuit between the SRs is to ensure there is no data corruption. I.e., if we simply pipe the data through then the data stored in A will be changed after every bit is fed out.
- Of course we dont use an AND2 in realworld implementations... with a bit of trickery we can use the DFFinputs as the control unit
