What do you think? I missed something huge and it's just impossible?

ONLINE CUDA EMULATOR PC

We could run the PC realtime simulator as a server, using an iPad (or the PC) for the display, and using two iPhone (bluetooth) for controlling joysticks or keyboard, for two players games. (so that it can be used on any PC / Mac / Tablet / Smartphone)Īnd I would do a PC/Win7 + Mac/OS.X + iPad program for the editor.Īnd a PC/Win7 only for the realtime simulator (needing a GTX 680 graphics card).

ONLINE CUDA EMULATOR FULL

I would do an online tutorial (in HTML5) showing the basics, some history, and my progress on the full 6502 processor. All running on CPU (GPU for graphics only).Īnd we could burn it all, and have it run in realtime once plugued in an emulated motherboard. It would run à 10 Hz (only) with animated signals.

Plus the wiring, of course (allowing junctions to split signals).Īnd allowing to connect a bus: any bits size (8, 16, 32, or 4, 24, anything from 2 to 32 bits), bi-directionnal, and drawn with a simple big arrow.Īnd we would be able to do blocks, we can duplicate and imbricate: for example doing a simple 1 bit complete adder, do a block of that, then duplicating 8 times and do a 8-bit adder, do a block of that so that it can be added to the full cpu schematic, keeping it simple & readable. With only AND, OR, XOR, NAND and NOT gates. I would like to do a graphical, ultra simple logic circuits editor. I aimed 4000 simulated gates, so that it can run all the NAND gates like the original (from visual6502) + some circuits around the 6502 for interfacing to the CPU I/O / RAM / Video.īut it could use much less if I'm reconstructing the CPU using simplier logic circuits (AND, OR, XOR, NOT). (I'm counting on the L2 cache for the pointers table: it would be read-only, so all that data will be loaded onto the L2 cache after the first pass)

ONLINE CUDA EMULATOR CODE

My PTX ISA code is certainly not correct, but it's just to count the LD/ST and ALU instructions, in order to do the math: only the GTX 680 would be powerfull enough to sustain the number of LD/ST instructions plus the necessary memory bandwidth. Video would be pure 60 fps (good for the PC), all 65 cycles would be the exact same duration (not a longer 65th cycle anymore), but the whole retraces timings and cycles would be still perfect, so it should not disturb any program that is doing any sync with the video: well programmed games should have no flickering, no jittering (just there are globally -0.1% slower).Ħ5 cycles x 262 scan lines x 14 Hz = 14 305 200 Hzĭivided by 14 = 1 021 800 Hz for the 6502 (1.022 MHz)Īnyway the original crystal wasn't that precise, it could run faster if very hot, or slower if cold. I would simplify the global frequency to 14 305 200 Hz, so that the video would be a perfect 60 Hz, instead of the standard 14 318 180 (4x NTSC frequency): that's a global -0,1% speed decrease only, but it simplifies many things.

The GPU would do all the 6502 simulation, the CPU would emulate the rest (I/O, memory, display) at 1 MHz. That would be run at 14 MHz, and the simulation run 14 times (1 MHz cycle for the CPU) before sending the table to CPU. Have a 8 bits table for previous values (1 bit only used in the each byte)Īnd have an other 8 bits table for the results Have a 2x 16 bits pointers table for circuits connections (but on spare time only: it will probably take me a year) I'll try to program that, at least do a proof of concept.

(I compared my actual GTX 570, and the new mid-range GTX 660 Ti, along with the top-of-the-line GTX 680) It shall be possible to emulate the 6502 (at circuit level 14 MHz signaling), in realtime, using the last GeForce GTX 680 graphic card. I've just made the math quickly, and on paper, it fits!
