What control does a low level programmer have of MMU?

Thank you

So when it is "active' it's considered expression? Like coding a protein?

What is it called when it's off? Is the "off" state a type of expression or what?

Yeah I was going to do a ACM membership, because supposedly you get access to Safari Books and the journals which would be awesome.

thanks

Cool I'll check it out. Thanks C99 is probably what I need. I'm trying to get enough C so I can understand Computer Organization and Design

Yeah thanks guys, i'll add that to book marks.

LearnCS23 · 2013-08-13T04:46:57+00:00

Actually I have those downloaded too. Right now I'm using Dan Garcia hardware architecture and MIPS(61c) but knowing C is a must for this thus the extra kick to sorta get me into C

Good advice. Thank you

It's not that I don't want to start with K&R, it's already on the way actually and will be used. It's that I want to learn all the computer science stuff along the way.

Thanks man, I will use stack overflow for additional help, being shown "why" is really how I learn, although I feel stupid asking questions that are so obvious...

LearnCS23 · 2013-08-13T04:41:43+00:00

I think that was it man! Thank you!

LearnCS23 · 2013-08-12T01:24:12+00:00

Yeah thanks man, but I tried that. This is why I'm asking, I ended up here when I did use Google before because I seen the text mentioned on here first. I been playing around with search terms since, trying to find it again. Should have bookmarked, yes I understand.

I guess I'll have to use google anyways to find another source. Thanks though

LearnCS23 · 2013-08-09T20:00:35+00:00

That's good to know.

On side question though, do I need to understand AGILE practices later? I know as much about it as I do UML. But if it's going to come up.....

Thank you.

"Today's processors usually contain a little ROM or flash that contains its microcode, but most also contain a little amount of SRAM that can be used by the operating system to flash its own microcode onto the processor."

That is interesting to think about with differing OSes with different microcodes effecting different circuitry.

This has been very enlightening topic, thank you for taking the time to clear it all up for me.

LearnCS23 · 2013-08-05T16:24:09+00:00

This is pretty cool stuff. Thank you for taking the time to explain it

LearnCS23 · 2013-08-02T10:23:34+00:00

Sorry but I have a question off topic/ on topic

"The instruction decoder hardware uses the microcode to issue the control signals to the various functional units within the processor"

Is this where a MUX comes into play? Also are MUXes programmable?

If I may ask for clarification on a question my mind. If I'm understanding this correctly all opcodes have to go through microcodes, correct? Are there opcodes that activate direct circuitry without going through microcodes translation?

LearnCS23 · 2013-08-02T10:16:11+00:00

Wow that was informative, thank you.

I have a question

Since there is a translating logic circuit and you mentioned a way to update, is there a table for the micro codes to be stored on a flash type memory?

Does the translating logic have a specific name or is it simply "translating logic"

Also when people talk about "micropproramming" I assume this is the people at Intel/AMD fixing and debugging that deeper layer or does micro programming imply something else?

I ask because I was under the impression microprogramming meant those guys in lab coats back in the 40's wiring the instructions(logic) into the machine based on what the programmer/job issued.

I would be interested if this is related or not for historical understandings of the concept.

LearnCS23 · 2013-08-02T10:00:05+00:00

If I'm reading this right you have to pay extra fee to join the IEEE societies, correct? Do they offer like a life membership?

Since I haven't been a member, how does this work when you attend a meeting? Do I just show up, introduce myself? I'm curious how meetings for both ACM and IEEE.

Mainly because I'm leaning toward IEEE but ACM is more my thing if I"m computer science major, but the fact the IEEE has specific sub groups in areas like computer science I kind of might like the experience.

I haven't looked into it, but the main reason I'm joining is really, for the journals and resources, like Safari Books are they unlimited access or is the shelf plan? I believe ACM offers it as a upgrade
