I Implemented the TIS-100 Architecture on my Atum A3 Nano

If you haven't heard of this game, you should definitely check it out. It is awesome.

I was playing it recently and it occurred to me that I could absolutely design the architecture in VHDL, so I took a swing at it. This is a short demo of some very simple functionality actually running on the board (this is very much still a WIP).

I realize this UI is disgustingly hideous. I just wanted to throw something together so I could actually test it out. I plan to eventually actually interpret the assembly commands, I just didn't feel like spending the time to do that before I actually got to run it.

Each outer core has a shallow input and output fifo. There is a UART controller that can parse messages to write instructions to each core, enable/disable execution, and write data to the input fifos. It also monitors the occupancy of each output fifo, and sends a message with the direction, index, and data of the values coming out of the cores. You can see, at the bottom of the UI, it is sending out incrementing values. ​

So, this UI is converting these instructions into UART messages and programming each core of the device. It is also reading from the UART and interpreting the messages as direction, index, and data (hence up[0]: x)

People that arent OP responding to comments

Has anyone noticed this? Every now and then, I see someone post something they created. Someone in the comments compliments them, then someone else (not OP) replies thanking them. Are these bots??

I hate my career and I can't do it anymore.

I am an electrical engineer, primarily doing FPGA development and verification. I wake up at 5, sit in a cubicle all day feeling like a complete and utter dumbass, and get home at about 7pm. I am consistently too beat down and exhausted to even enjoy anything. I basically get home and stare at my phone or drink until I fall asleep. I can't even talk to my wife about this, because all she tries to do is tell me it's my mindset that needs to change. I can't hear that another time and maintain my sanity. I fucking suck at this job and it's drained me of all passion for anything else. I don't know what to do.

Manually Converting DDR to SDR

I have an Atum A3 Nano, which has an RGMII interface from an ethernet phy connected directly to the fpga. I originally tried to hook it up to a GPIO IP that converted DDR to SDR, but ran into all kinds of problems with the clock coming from the phy (placement was complaining and it wouldn't compile). As a test I just implemented it with plain vhdl using rising_edge, falling_edge, and a pipeline. Turns out it worked, and i was able to see the data coming through with signal tap. Is there any down side to doing this way? Is Quartus just infering the same thing that the IP does anyways?

Modelsim free edition -mixedsvvh?

My typical work flow is design in VHDL and simulate with SystemVerilog (some may think I'm crazy). I typically do this by compiling all of my VHDL files with the -mixedsvvh flag. Whenever I do that in the free version of modelsim, however, it says it's not supported. Am I just SoL here, or is there some other method I can use?

Wanted to capture a dream I had on paper (sorry, not much of an artist)

Not really sure what it means.

Evil Balloon

Last night I had a dream that I was desperately reaching for a floating lightbulb that was dimly lighting an otherwise extremely dark room. No matter how hard I tried, i couldn't reach it. In the room was floating a yellow balloon with a smiley face (think of the Walmart balloon), but it had angry eyebrows. Below it was a large pile of empty alcohol bottles. The face on the balloon didnt move, but I could hear it saying something along the lines of "frivolity. Think about work. Work is more important."

Have I experienced the start of an OBE?

New here. Im posting here because I'm blown away at how similar my meditation techniques are to the ones mentioned here, which I discovered after some google about my experience. Last night I had a really interesting experience, but I'm not sure if it was just a dream.

For years on and off, I have meditated by laying still (eyes closed with ear plugs) and visualize every thought popping into my mind, then "manually" pushing it away. Most times, I just fall asleep eventually, but every now and then I experience a sensory deprivation effect for a while first. That happened last night, along with something new. For what felt like the entire night, I laid there with my eyes open (after having fallen asleep), and i was completely still staring at the room around me. It was ALMOST correct, but some furniture and the size was off. I'm not sure if it was sleep paralysis, because I dont recall even wanting to move. I just wanted to lay there and observer. Eventually, I jolted awake and sat up, everything perfectly normal, maybe an hour later (although hard to say for sure). Has anyone experienced something similar?

P.S. I plan on listening to the tapes tonight and seeing if I get any further. Are the ones on Spotify ok?

Time dilation and radio signal

This has been bugging me for a long time.

Let's say I am on the surface of a planet, and my friend is on a space ship far away from the planet. The gravity on the surface is such that, due to time dilation, I am experiencing time at half the rate of my friend.

Now let's also say that we each have a radio that is powerful enough to communicate at our distance. I hold the button and say "hello." When my friend's radio play that hello back at double speed? If not, why?

edit: half speed, not double speed

The top post in this sub explains how there have been studies suggesting the possibility that electromagnetic fields could be the source of consciousness, as opposed to a by-product.

Well, based on this ghost murmur technology, our hearts must have a fairly complex and unique electromagnetic field. A large part of the human experience is "feeling" with one's heart. So, what if our hearts actually dude have a consciousness that is simply weaker than that of our brains?
