It's been too long! Congrats on the programming job!

It's been years since I've been programming much. DBPro used to be my language of choice, but it's so hard to get it working these days (finding a good IDE, installing the right version of DirectX, etc etc). I've had some random experiments I've wanted to do for some time, so I finally bit the bullet and began looking for a language that would suite me. I ultimately decided on C, and I simply love it. Best language I've ever used! I enjoy its utter simplicity, and I've never been a fan of OOP, so it's perfect. I came up with some random instruction set and I've been implementing an emulator to run it over the past few weeks, which has been a great learning experience. The core emulator works, but I have to manually enter values into an array to program the emulator, and it can only output to the console so far, so I next need to dive into some file IO and graphical interface stuff. Optimization is another challenge -- I have it up to about 125 MIPS at the moment, but I've had simpler prototype emulators run in excess of 270 MIPS.

Are there registers called pft, pfft, pffft, and pfffft?


Other than this youtube channel, I've been procrastinating on more important things and occasionally working on Exotreve.

I should name some that! It's a load store architecture, but has many registers. I currently have it set to 512 registers -- probably not practical in the real world, but hey, this is an emulator! The instruction set is a little inefficient in size, with each instruction being 6 bytes. The first 2 hold the instruction and addressing mode for each of the (up to) 3 operands, and the other 4 (or 6) bytes hold the 2 (or 3) operands themselves. I've since come up with a more efficient way to represent instructions, but I'm too lazy to rewrite the emulator for a 4th time.

It seems that, quite strangely, bitwise operations are taking a rather long time to perform. I use the bitwise operations (mainly AND) to break the first two bytes into instruction and addressing mode codes. That alone is eating up like a third of the total run time.

I am now confused as to what the correct ear cleaning technique should be. You should make a video on that!

I have a great idea! Make one of the registers not work properly and don't document which one.

I mean, each instruction is 6 bytes long.

Quote: "So what are your addressing modes?"
Register, register pointer, address, address pointer, and literal. Each opcode can have its own addressing mode, which explains the 9 bits that specify the addressing modes

The simpler system I came up with reduces the two bytes instruction down to one. I could then have dynamic operand sizes depending on whether they pertain to a register, address, or literal, but that would require more logic in the code and perhaps a slower emulator.

Here's the spec of the instruction set:

You promise me gameplay and put me through hell
Chains of routers got a hold on me
When latency's risen you'll play poorly

Oh, you're a teleporting gun
Oh, it won't let me run
No one can save me
This match is no fun

They're coming soon, that's what the reserved is for! See, I'm designing an instruction set, yet I've never actually programmed in assembly before. So I guess it's kind of a learning experience like that -- I keep realizing that I need extra features and instructions through experimentation and then adding them. It was when I realized that I needed some sort of register pointer capability (I was trying to write a program that would fill a small array) that I redesigned the instruction set to be expandable (albeit inefficient in size).

On that note, my original goal was to emulate a one instruction set computer, specifically SUBLEQ. That was super simple (like 20 lines of code for the main loop) and was really fast, I think I had it up to 370 MIPS. I then realized that I could add extra instructions by creating a small number of address that could not be jumped to (instructions trying to jump to those addresses would be interpreted as different instructions, like add or move). That got really complicated and convoluted, so I came up with what I have now.

Quote: "How do your conditional jumps work? Do you have a status register?"
They're a little funky so far. They're implemented as compare and jumps. One register is set aside as a ccompare register, so values you want to compare with are moved to that register. Then, the compare and jump instructions each accept two operands. One is the value being compared with the value in the compare register, and the other is the address being jumped to. So far it jumps if the operand value is less than or equal to the value stored in the compare register. Not very elegant, but there's room to expand. A status register is a great idea -- the instruction would jump if the value in the status register is equal to the value specified by the instruction.

Here's a simple program that iterates a variable X up to 20, then resets it to 0, using the compare and jump instruction for flow control:

I have just watched this video you have posted and that you have shared on these forums. Upon watching that video, I have figured out that the pillows contained within that box may have a low temperature. If you ever decided to sleep with those pillows, and had been using them in the manner depicted in the video you have created and posted and shared on this forum, and if you prefer pillows not to be cold when sleeping with them, you would need to warm the pillows first. Be advised that a microwave oven is not the proper tool for this task.

The pillow is near the intake vent, so it's probably fine.

Ah nice, I passed my test on a CBF600, so a cousin, I guess, but I am loving my Kawasaki Vulcan S, been riding her for 4 weeks now and she rides beautifully. We can start out own motorcycle club on the forums. And Baxslash can bring his pure American sandwich.

Also, I have gotten into this thing that the kids are totally down with these days and I don't mean Tide Pods, but Monster Hunter World, I managed to snap this screenshot and in my head all I'm am thinking is "ow my hair, my hair, please not the hair". Derek Zoolander would not stand for this. I mean, the dude can breathe ice, but nope, straight for the hair.
