So its just an down/up 2 bit counter with edge protection. This is also called a saturation counter, IE) when decrementing and at state 00 it will remain at state 00 instead of decrementing to 11; when incrementing at state 11 it will remain at state 11 instead of incrementing to 00. The MSB is the BP's prediction(1=take, 0 =dont take), the LSB is the last outcome of the CPU(did it take the branch or not?; 1 = taken, 0 = did not take). The down/up control line comes from the result of the branch after the result is found(1 clock cycle later).]]>

*First I review basic AM waves and what they are.

*Then I try to show the most basic way to capture a Pure AM signal with a Diode and RC envelope Detector.

*Next I describe how engineers are not mathematicians so we do not need to derive every transform that we need(Z, Fourier, Laplace, etc, etc..)

*With that in mind, I review how to move a low frequency content into a higher frequency by multiplication of a complex exponential or sinusoidal signal.

*I explored a Modulation Table that shows the form of the carrier signals for all different forms of AM(AM, DSB, VSB, SSB, and QAM). This table also shops the respective Fourier Transform, Magnitude and Phase spectrum(with respect), Bandwidth, Power, and Modulation and Demodulation methods.

*Next I explored my MicroElectronics textbook for a MOSFET CS amplifier(which is the MOSFET equivalent to a BJT Common Emitter Amplifier used in my circuit.)

*Lastly I simulate an AM signal and then rectify and amplify it to produce an output to emit to a speaker

TL;DR: fuirippu built a machine; it's big, slow and not very adaptable

My first Computer (the behemoth)
First some specs...

• embarrassingly high ticks per cycle
  
• 8-bit processor
  
• 8 bytes RAM, 8 bytes data ROM
  
• 4 bit program counter (16 bytes PROM)
  
• fixed 8-bit instruction set
  
• conditional branch
  

Background
Yeah, I know: it's not gonna win any prizes like that. And wait til you see it: it's huge. Also, it took me probably a month and a half to build (I have a few no good excuses). Despite all this, I'm pleased with the result and I got to have fun learning stuff along the way.

At the start of 2015, I had got back into Minecraft after a long break. I had just started redstoning and built a few devices for survival mode. I had heard that people had built computers with redstone, and I had seen some YouTubes without really studying them. I wanted to build a general computing machine of redstone. I had built sequential logic circuits and knew roughly how these could combine into a computer (it's all NAND or NOR gates, right?).


Project Goals
I would base it on a simple processor I knew a bit about, and give it a simple task...
a Motorola 68000 tribute, capable of executing a recursive subroutine

This goal was too ambitious, so it got downgraded to...
a Zilog Z80 clone, capable of executing a routine to calculate factorials

Later this became...
a computer based on the MOS Technology 6502, capable of executing a multiply routine[/i]


First Steps
Things moved along and I made a 1-bit memory cell using the classic torch-based RS latch from the Minecraft Wiki...

4/1/15

It was rubbish, I re-designed it...

4/1/15

It was still rubbish, but I didn't know any better. It was at least stackable, 2 blocks high. I stacked bits vertically to make a 4-byte cell wired to an elementary decoder...

9/1/15

After another two weeks or so, I had 8x 4-byte cells all wired up to a decoder, and I was starting to group input and output into busses...

22/1/15

It was only in the last week that I thought: there is no way people are building these machines without at least some kind of copy and paste. Wiki taught me the commands /clone and /fill: they were awkward to use, and I made plenty of simple geometry mistakes, but compared to what I had been doing before, they were heaven-sent.


Inspiration or Plagiarism
At this time /clone and /fill were rocking my world, but bussing my memory cells was a nightmare. I started watching YouTubes, and followed the playlist “Building a Minecraft Computer Tutorial” by bennyscube. This led to a total re-design of memory cells (use bennyscube's), and to the design of an adder (use bennyscube's).

It had taken me a month to make 4 bytes each of RAM and ROM without de-mux, connected to an 8-bit adder with three registers. Luckily I wasn't in a hurry.

[2/2/15]

More geometry mistakes with /clone, along with a painful experience rotating the adder by hand, caused me to decide it was worth investigating mods: Forge, WorldEdit, revert to previous version. Boom! Suddenly just with //copy, //rotate and //paste, I had god like power to build my computer. It would be another week before I learnt //stack and //schematics.


Finishing Up
After five weeks the memory had been extended and the end was in sight. I had a ToDo list. There were two big items: program memory/clock, and branching. Bennyscube's tutorial doesn't use a register for a Program Counter, instead each operation embeds a goto statement into its code. This gives his machine branching, but not conditional branching. I wanted a counter with parallel load. Google showed me Hans Lemurson's PC – noisy but functional and extremely compact.

One final problem solved – transient signals on control lines because I hadn't accounted for the need to clock the current instruction into a register before the next instruction was fetched – and my computing machine was finished. It was about the 16th of February. It had taken about 6 weeks, and has rubbish specs, but I'm still a little fond of it.

I haven't tested the clock speed: the components are so slow and the architecture so basic, that I run it at 32ticks – 16 to fetch and decode, 16 to execute (mumble-mumble pipeline). It seems to do OK multiplying 8-bit values in a loop with no overflow handling.

There's a gallery here if you haven't seen it with my ORE application.


For the Next Build
The main lessons I started my next build with are

• have more program memory
  
• a tiny amount of RAM is probably enough (unless you want to execute code from it, or use it as a stack during recursion)
  
• speeds might never be truly satisfactory without pipelining

P.S. The idea of this calculator wasn't to make a bare-minimum tutorial like many of benny's series, but to go all out. The final product will likely be very similar to Newo's newomadder calculator with higher bitwidths.
