Like I said - I have no idea where to even start! I'm not asking for answers to the question (it's not even homework, it's a past exam paper I'm looking at), I just want some tips on how I can answer it. I'd put in the time if I had any idea of where to even start. I can't find anything at all about it.

Anybody know where I can learn how to answer this question? I have no idea where to even start and I can't seem to find anything on Google. Any help would be much appreciated. Thanks.

Hi, Can anyone explain to me how to do pipeline diagrams? Here's an example of an exam question: I don't just want the answer to this question, if someone could help explain to me how to do it that would be great!!

Thank you! Was referring to "the four units with inputs/outputs, CP, D, Q, and Q" yes. You're totally right, I just had a look around in CircuitMaker and there are some flip/flop circuits (that look similar to the diagram) - just have to find the right one now! I'm a bit confused though.. do you think the task I've been given is really as simple as re-creating the circuit that is in the logic diagram?

You must construct the following layout : and simulate it, additionally using switches and lights for data input and display. The simulation must carry out the operation X + Y -> X. Produce a table of control switch settings which carries out the operation described. I'm guessing that X, Y, A should be gates, and O should be the output? Do you think that's correct? Also for the ALU, how does that work? I've never used ALUs in CircuitMaker before so I'm not quite sure how they work.

Thanks! I'm trying to simulate the circuit in circuit maker, do you happen to know what the 3 "box" shaped objects in the middle of the logic diagram are called? http://www.datasheetcatalog.org/datasheet/motorola/SN74LS173N.pdf

Thanks! I had a look at the truth table and I'm a bit unsure what it all means. I'm used to seeing truth tables with just O or I - off or on. There's lots of weird symbols in there so I'm not quite sure what they mean in terms of simulating that symbol in the circuit? Do you have any ideas?

Hi, For my architecture work I need to identify the 4-bit register with tri-state outputs 74LS173 and the 4-bit ALU 74LS181.I need to research their operation and design and simulate a test layout for each, using logic switches to input data and logic displays to show outputs, and 4-bit data items and pathways. Can anyone give me some ideas on how to get started? Thanks.
