Advanced Redstone Computer Tutorial 5: CISC vs RISC

In this video we discuss the pros and cons of CISC and RISC instruction sets. I also discuss which one I'm going to use in the tutorial and why so.

I'm following this tutorials to do a processor in real life with gates, you just explain so freaking well!

[alexjones]

I am interested in an Instruction set series.

Your Videos are more informative than my Computer Science Professor's Lectures

"Ludicrous speed" I'm dead XD Love the videos, I just wish I would've found them sooner, they've been a real help in my attempt at a computer of my own.

I feel like you've talked about this before, but what's your background? How do you know all of this?! (awesome series btw!)

[Palerider]

get that instruction set series started :D

[bennyscube]

Not quite, but you're close. Most redstone computers don't use instruction sets; you program with raw instructions. An instruction set takes the instructions that are useful together and organizes them so it's easy to use and program. For instance, rather than having a subtract command be "invert B, add 1, " you would have a dedicated code for subtraction, and only let useful data be used with it such as numbers to subtract and where to save the result.

Learning to make a computer in minecraft means you learn every detail of computing, so this is a better series than one about building one in real life, because most real tutorials go as far as "the heat sink cools the components. Snap the processor into the motherboard. " this is more in-depth.

[bennyscube]

I don't really have much of a "background." I just study this stuff for fun on my own.

I made my own IS ASSLISC add subtract save load instruction set computing

@Owen Baggaley : BCD means "Binary Coded Decimal" so instead of representing number in binary like this: 1010 (10 in dec) you represent them as this: 0001 0000 so 4Bits represent one digit of a decimal number^^

Plz get next vids out ASAP!!!! We're lovin'm

i feel like CISC took over the desktop CPU market mainly because Moore's law allowed Intel and AMD to keep improving on their original choice of architecture. I think in Minecraft, it would be more practical to just use a RISC architecture if you are moderately skilled in programming. also, Moore's law doesn't really apply either since you can only make an XOR gate so small... unless Mojang releases newer redstone components that make them more compact but yeah.

Also, hybrid CPUs exist

Evolution theory suggests that the egg came before the chicken as any mutation that lead to the chicken as we know it could have only occurred within an egg (or upon conception, which leads to an egg that will hatch a chicken). :D

[ZackeryFox]

I'd like to know how you go about designing your own instruction set.

[bihazards]

Designing an Instruction Set tutorial :D Make it! :D

[bennyscube]

It's relatively accurate, yes. :)

Would it be possible to have CISC AND RISC IS's in one computer? You would use a flip-flop to toggle between the two, you could program the computer to tell when an intensive program is being called, and have it switch to CISC, but wen a very simple on is being called, switch to risc?
