assignment question

Bartonprince

I'm having a nightmare time with this question and would love a hand with it from any techies.

1) "Reproduce a simple drawing of a diagram and explain it's main components and their role in the PC system."

Now in the reference drawing there is a diagram that has Rom, prom, flash memory <

---

> Ram, Buses, LS and L1 Cache which then leads to control unit, decoder, program register, instruction register, general purpose register, then that leads onto another set of registers, and an arithmatic and logic unit, which finish at processor.

And my head is baked, does anyone have a good explanation of how all this stuff works and a diagram that would be helpful?

Cheers

Well....for starters....the L1 cache is inside the processor. As are the registers. Any chance you could reproduce that diagram in some way?

The rom / prom / flash are probably all part of the bios. The busses are for transporting data between memory and processing units (processor, graphics card, network card, etc.).

erm i'll try.

Maybe draw a pic of it in mspaint or something. I'm off home to internetless land now. Good luck.

Ok i think what it means is, i have to draw the diagram again, and just explain what each bit does. (It says the main ones)

So here are the components.

ROM
PROM
Flash Memory
RAM
Buses
L2 cache and L1 cache

Control Unit
Decoder, program register, Instruction register, General Purpose Register

Accumulator
General Purpose Register
General Purpose Register
Arithmatic and Logic Unit

Processor.

SO i need to explain what these all do and how they contribute to the system functionality

Khannie

Ah well....in fairness, I can't answer the question for you.

A quick google on each of the elements will tell you what it does.

Most of the non-memory stuff you have there is all inside the processor though. i.e....

Control Unit
Decoder, program register, Instruction register, General Purpose Register

Accumulator
General Purpose Register
General Purpose Register
Arithmatic and Logic Unit

and all of the registers are just fast, small bits of temporary memory inside the processor.

Without sounding dismissive, this was my usual port of call when researching college assignments.

if you want the easy way out: go to your college library.
Any half decent comp. arch. book is bound to explain the parts in detail and have a diagram..
