1/N Happy #FPGAFriday! I just wanted to give a quick description of why this is different than previous designs. None of my previous GPUs were designed to be practically useable. I hardcoded vertices/shaders/texels in a BRAM to test rasterization/texcache/and shaders. They were…

OK guess this is goodbye, twitter. Any interested parties can see me at the other place, same username

@bdjoetsu I’m so sorry you had to go through that! Did someone at Yodobashi recommend it to you? Because you always have to be careful with おすすめバチ

Getting hundreds of adds per day over at The Other Place, so I guess we’re really all moving now? Guess it’s time to ruin another service with my unsolicited FPGA bad takes and SPU supremacy? I’ll probably keep my twitter account for archival purposes as I move over

@tom_forsyth Oh I get that it’s not always easy/doable, but as someone who spent much of the last three years working out if various single cycle stalls are expected, a HW understanding miss, or something else, you can usually get pretty far using HW docs, perf counters, and simulation

@jetha You’re not missing out. That place is お値段異常 ニトリ

RT @JBrooksBSI: @okonomiyonda @falconerd PS2 VU's were great! I used EE + VU0 + VU1 in triple-core lockstep for fast vertex transform/cull/…

@MrJayLC @SebAaltonen Just saying, FPS is the second worst way to profile, with only “feelings” being worse

@slembcke Yeah, what the hell, why did you stop posting these? I need to know more of Tigger’s excellent lifestyle

@ChuckCharless True, it’s not always easy, but if you are clever/lucky, it’s often possible to work backwards from the ASM and work out how you got there

Who’s gonna provide the flowers for your Military Fashion Show?!

@tom_forsyth Agree, however I like to reason about how many clocks a shader should take. You can usually get very close if you know the various FIFOs that can fill and exert backpressure. Once that matches you can do a second pass to look at the effect of instruction sequences on power/clock!

Azerbaijan is wild! I feel like I don’t make enough money to even be allowed to get off the train here

@regancarver An excellent point. But just to be clear, I was mainly talking about profiling. When profiling, judging if a change is faster just by feel is a Very Bad Idea. GPU clocks gives you the best feedback in many situations, although modern power management makes things more fun :)

@ObsoleteSony Hypothesis: I sit next to someone called Inoue-san that has the same birthday as Inoue Toro. I’m beginning to wonder if he’s the real life inspiration :)

Think I may have had a stroke today, because I told my coworker that I didn’t remember 最終兵器彼女 being so traumatic

@eevblog

@ModernVintageG @godfree Sure, but I’d argue not just for playing games, but for gamedev as well. Although PS2 would also be an equally strong contender there

@RaraSensei You are a terrible person! Why would you prioritize the literal survival of a total stranger over the stock portfolio of your own father </sarcasm>

Back still really hurts, so I’m going to continue dispensing life wisdom So maybe don’t, like, go out of your way to intentionally teach your cat what buttons to press to turn on the fan. Doubly so if you have a cat that looks for ways to get you out of bed at night
