ChanServ changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic.

I was gonna try remote vectorizing today, but I don't think xpra does well w/ it lmao
<cr1901>
And this laptop I have w/ me isn't powerful enough to open the entire die file
<ej5>
what are you doing the vectorizing with?

<Lord_Nightmare>
the spritesmind 68k thread, nemesis developed another vectorization/tracing helper tool
<cr1901>
? I use inkscape
<cr1901>
anyways will this new tool become vaporware like exodus?

<cr1901>
err abandonware*
<Sarayan>
LN: it's a visualization/annotation tool, not a tracing one
<cr1901>
Sarayan: And well, isn't, strictly speaking, 68k fully RE'd b/c you and kevtris worked together?
<cr1901>
recently*
<Sarayan>
yeah, kevtris prefers if it's not too talked about
<Sarayan>
but I guess it was for before the NT announce
<cr1901>
mmm

<Lord_Nightmare>
wondering how much more comple the 68010 is vs 68000
<Lord_Nightmare>
x
<fseidel>
not much
<fseidel>
there's a small prefetch buffer which allows the CPU to execute small loops faster
<fseidel>
you get 2 slots, so if one instruction is your loop body and the other is a DBRx instruction, you don't have to keep spending bus cycles to fetch those ops
<fseidel>
there's also a few more states in the microcode to push the state needed to resume from a bus fault
<fseidel>
that's basically it
<fseidel>
that first feature is what Motorola call "loop mode" in the docs, which is a stupid name for what it really is, because it's not really a new mode
<fseidel>
also, the microcode was edited to make MOVE SR, x trap in usermode
<Lord_Nightmare>
does the 68k itself have a prefetch buffer of some sort, just the 68010 actually took real advantage of it?
<Lord_Nightmare>
or was it an entirely new addition?
