00.00.40 #       <[IDC]Dragon> there are some mort CRT tidbits which could go into IRAM
00.00.49 #       <[IDC]Dragon> see rockbox.map
00.01.11 #       <[IDC]Dragon> e.g. the mul/div subroutines
00.02.22 #       <amiconn> Grayscale framework and jpeg update including that committed now.
00.02.32 #       <[IDC]Dragon> thanks
00.03.47 #       <amiconn> If there is space left in IRAM, of course this space could be used for speedup
00.04.20 #       <amiconn> The question is: how do you tell the compiler/linker that it should put a library routine in IRAM?
00.04.46 #       <[IDC]Dragon> I think that's easy
00.04.57 #       <[IDC]Dragon> just name it in that section or so
00.07.03 #       <[IDC]Dragon> we can almost fit the whole libgcc.a
00.07.36 #       <amiconn> Anyway, routines that don't access other memory and are not called in short sequence won't profit that much from putting them into IRAM
00.07.37 #       <[IDC]Dragon> which is 856 bytes
00.08.26 #       <amiconn> The only thing that would avoid is the double page miss (one at call time, one at return)
00.09.00 #       <[IDC]Dragon> and probably twice the bus speed
00.09.26 #       <[IDC]Dragon> 816 bytes left#
00.09.59 #       <amiconn> The sh can execute one instruction (16 bit) per cycle, and read from external ram one word per cycle (16 bit), as long as there is no page miss, since we have no extra wait.
00.11.14 #       <amiconn> Imho, if we want more speed, we should try to put routines into iram that _do_ access other memory.
00.11.55 #       <[IDC]Dragon> OK
00.12.03 #       <amiconn> If these are not in IRAM, this produces two page misses per memory access (one for the access and one for the next instruction fetch)
00.12.54 #       <amiconn> I think of strcpy, strcmp..
00.15.33 #       <[IDC]Dragon> whow, now _this_ is what I call scrolling!
00.15.50 #       <amiconn> Last time you talked about IRAM, you mentioned that some additional space is needed for the debug builds. Did you take this into account?
00.16.08 #       <amiconn> :))
00.16.16 #       <[IDC]Dragon> no, I didn't :-(
00.16.57 #       <[IDC]Dragon> really cool, that scrolling!
00.17.05 #       <midk> what scrolling
00.17.07 #       <midk> what did i miss
00.17.11 #       <[IDC]Dragon> (just can't get enough of it)
00.17.25 #       <[IDC]Dragon> improved JPEG viewer
00.17.30 #       <midk> how does it look?
00.17.34 #       <midk> can't test until tomorrow
00.17.39 #       <amiconn> faaaaaaaaaaaaaaaaaast
00.17.42 #       <[IDC]Dragon> faaast
00.17.47 #       <midk> YAY
00.17.55 #       <[IDC]Dragon> oops, mine was too short
00.18.02 #       <amiconn> ;)
00.19.10 #       <amiconn> Btw: the new 8-pixel subroutine uses 12 registers at once. Pretty close to the available 16...
00.21.44 #       <[IDC]Dragon> saw that long streak of shift and rot
00.23.01 #       <[IDC]Dragon> mattzz could change his mandelbrot then again, to output 8 lines at a time
00.23.16 #       <amiconn> Probably the more interesting part is the asm block above that - the precalculation of all 8 patterns, with random shift.
00.23.55 #       <amiconn> Hmm, the problem with the mandelbort is that it calculates pixel by pixel.
00.24.40 #       <[IDC]Dragon> we had it 8-line-wise once already, remember?
00.24.48 #       <amiconn> If he wanted to take advantage of the speedup, he would have to use a little bitmap (8 pixels high), render into that, and then draw that.
00.24.57 #       <[IDC]Dragon> so?
00.26.46 #       <[IDC]Dragon> goodnight folks
00.26.52 Quit    [IDC]Dragon ()
00.26.53 #       <amiconn> nite
00.27.07 #       <amiconn> Ooops, too late
00.30.49 #       <midk> heh
00.32.44 #       <elinenbe> amiconn: what type of speedup can you expect with the new grayscale routines?
00.34.21 #       <amiconn> elinenbe: gray_fillrect() and gray_drawgraymap are 2..3 times as fast (for larger rectangled and images).
00.34.44 #       <amiconn> Scrolling left/right is also significantly faster, scrolling up/down by 8 pixels a bit faster.

00.35.13 Nick    edx{jogging} is now known as edx{code} (edx@pD9EAAB77.dip.t-dialin.net)
00.35.24 #       <elinenbe> I'll compile the latest and tell you if you deserve congradulations!
00.35.25 #       <elinenbe> :)
00.35.41 #       <midk> oh amiconn btw i like the new grayscale demo
00.35.57 #       <amiconn> A bit of speedup is expected for other functions too.
00.36.11 #       <midk> hmm sort of a dumb question... is there no way to remove the horizontal lines that run across the lcd?
00.36.24 #       <elinenbe> amiconn: how long until we see anti-aliased grayscale fonts and a grayscale interface :)
00.37.09 #       <amiconn> elinenbe: I don't thinkl there will be a grayscale interface, but font support is scheduled next (not anti-aliased yet)
00.37.35 #       <elinenbe> amiconn: sounds great!
00.37.50 #       <elinenbe> I think it is fabulous....
00.38.31 #       <amiconn> midk: Unfortunately not. These lines are caused by interference of the grayscale frame rate with the internal scan rate of the lcd, which isn't absolutely constant and cannot be measured by a program.
00.39.05 #       <elinenbe> is the haxx.se site down?
00.39.15 #       <elinenbe> boo!  can anyone else access it?
00.39.26 #       <amiconn> Works perfectly here...
00.39.45 #       <elinenbe> really?  can't access the cvs or the web page from here.
00.40.30 #       <amiconn> Just clicking my way through ViewCVS...
00.41.04 #       <elinenbe> i just use cygwin...
00.41.24 #       <elinenbe> something is up with my provider...
00.41.39 #       <elinenbe> amiconn: not to sound rude or anything, but what is the benefit of grayscale fonts?
00.41.41 #       <amiconn> Grr, there are TAB chars. Again!
00.41.50 #       <elinenbe> or is it just completing the grayscale framework?
00.43.01 #       <amiconn> This is just completing the grayscale framework, and not about real grayscale fonts but showing the regular rockbox fonts within the grayscale are, with selectable foreground & background values.
00.43.15 #       <amiconn> *grayscale area

00.44.09 #       <elinenbe> ah...
00.44.22 #       <elinenbe> well, can you place the regular font in any shade then?
00.44.32 #       <amiconn> yup.
00.45.16 #       <elinenbe> cool!
00.45.23 #       <amiconn> And you can select if the background is transparent or has another shade (just like for 1-bit bitmaps now)
00.45.27 #       <elinenbe> it would be nice to implement that into the WPS
00.45.37 #       <elinenbe> along with a "wallpaper"  (now I am getting silly here)
00.45.48 #       <elinenbe> what is the IP you get for rockbox.haxx.se?
00.46.26 #       <amiconn> 193.15.23.131
00.47.06 #       <elinenbe> same here... ah... I'll just wait until later.
00.48.04 #       <elinenbe> amiconn: you really have put some great work into rockbox... thanks so much!
00.48.22 #       <elinenbe> amiconn: keep it up!  it's exciting to see what you think of.
00.48.23 #       <amiconn> Strange. There was another user approx. 2 hours ago who also couldn't access rockbox.haxx.se
00.48.42 #       <elinenbe> maybe there is a problem from the states?
00.48.50 #       <amiconn> But for Jörg as well as for me it worked the whole time.
00.49.19 #       <amiconn> Maybe, since we both are in ol' europe here.
