Central processing unit
A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The term has been used in the computer industry at least since the early 1960s. Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.
The form, design and implementation of CPUs have changed over the course of their history, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that fetches instructions from memory and "executes" them by directing the coordinated operations of the ALU, registers and other components.
Freescale 683XX
The Freescale 683xx (formerly Motorola 683xx) is a family of compatible microcontrollers that use a Freescale 68000-based CPU core. The family was designed using a hardware description language, making the parts synthesizable, and amenable to improved fabrication processes, such as die shrinks.
There are two CPU cores used in the 683xx family: the 68EC000 and the CPU32. The instruction set of the CPU32 core is similar to the 68020 without bitfield instructions, and with a few instructions unique to the CPU32 core, such as table lookup and interpolate instructions, and a low-power stop mode.
The modules of the microcontroller were designed independently and released as new CPUs could be tested. This process let the architects perform "design-ahead" so that when silicon technologies were available, Motorola had designs ready to implement and go to market. Many of these submodules have been carried forward into the Coldfire line of processors.
The microcontrollers consist of a series of modules, connected by an internal bus:

by: Big BoiAnd it's you that's on my computer screen
Cause it's you that's on my mind
And it's you that's on my computer screen
Cause it's you that's on my mind
Cause it's you that's on my mind
The world is yours as soon as you log on
I'm long gone like the dro that's blown in the wind, friend
Pretend that this life is but a dream then reality syncs in
The fantasy begins and it never ends
We like to role play, throw on some Coldplay
Go get some drugs and alcohol, fuck our whole day
Now we're trapped in the matrix
While Big Brother out here making movies, nigga, don't say shit
And it's you that's on my computer screen
Cause it's you that's on my mind
And it's you that's on my computer screen
Cause it's you that's on my mind
Cause it's you that's on my mind
The information age (age)
The age of information, but we're still a slave
So let me behave like a coon, bring the goons, go out and sell dope
That's what they shoving down our throat so I choke
And regurgitrate truest lyrics I ever wrote, folk
My crew is loc'd out without the bandannas
Yet we keep it cracking like a egg yolk, nigga, that's Atlanta
By way of West Savannah
And it's you that's on my computer screen
Cause it's you that's on my mind
And it's you that's on my computer screen
Cause it's you that's on my mind
Cause it's you that's on my mind
As I scroll through the centerfolds
Wishing that the screen was three-dimensional
I know it doesn't seem too conventional
But it'll do untill I get you in the physical
And it's you that's on my computer screen
Cause it's you that's on my mind
And it's you that's on my computer screen
Cause it's you that's on my mind
Cause it's you that's on my mind
The flash memory that I'll hold is all I know of time
What was waiting all along is all I have to realize
I've got the dial tone
The glowing screen, it means we're not alone
And it's you that's on my computer screen
Cause it's you that's on my mind
And it's you that's on my computer screen
Cause it's you that's on my mind
