not sure about c1k and c3k. but worse than c860 with w100 hard accl driver.  [/quote] the performance are worse cuz the lcd (wich is bigger) or it it simply a ploblem of dirver supporting video acceleration ? does the c1000 use the same ship than the c860? in a purely hardware point of view wich one of those ship is the best ?? |

without the chip technical manual, no hope.

Sharp's tc6393fb.h has enough information to experiment. First, I'd try modifying the fill command to draw colored boxes on the screen. This is very useful for accelerating window managers, as they tend to draw the backing color, then the objects on top. The source copy would be great for moving windows, scrolling windows, scrolling the console, and drawing console characters.
The TC6393 has 1MB of video memory. The default 640x480x16bit mode only uses 600kB, leaving 424kB for console fonts, bitmaps, etc, for source copy. Also, 424kB is enough for one large 528x400 buffer. With a custom mplayer plugin, mplayer can render to that off-screen buffer, then StretchBLT the buffer to the 640x480 screen. It looks like StretchBLT has vertical reverse and horizontal reverse options, too, so you can flip horizontal, or flip vertical, or rotate the video 180 degrees in hardware. I'm working on the 2.6 kernel at the moment, and I'll work on video acceleration at some point (it's a low priority, so it could be a while). If someone wants to experiment and help out, that'd be even better. =) The TC6393's LCD controller has five accelration commands: PXAIO_COMDI_CMGO - Cursor Move? PXAIO_COMDI_FLGO - Fill PXAIO_COMDI_SCGO - Source Copy PXAIO_COMDI_SBGO - StretchBLT PXAIO_COMDI_LDGO - Line Draw Out of the set commands, we can group by ones that take a pixel color as a paremeter: PXAIO_COMDI_FILL - fill color PXAIO_COMDI_TCLOR - transparent color for Source Copy ones that take a memory address as a parameter: PXAIO_COMDI_CSADR - cursor screen address? PXAIO_COMDI_PSADR - physical screen address? PXAIO_COMDI_POADR - physical offset address? PXAIO_COMDI_DSADR - destination screen address? PXAIO_COMDI_SSADR - source screen address? and ones that take a x or y offset or pixel count as a parameter: PXAIO_COMDI_CHPIX - cursor horizontal pixels? PXAIO_COMDI_CVPIX - cursor vertical pixels? PXAIO_COMDI_PHPIX - physical horizontal pixels? PXAIO_COMDI_PVPIX - physical vertical pixels? PXAIO_COMDI_PHOFS - physical horizontal offset? PXAIO_COMDI_PVOFS - physical vertical offset? PXAIO_COMDI_DHPIX - destination horizontal pixels PXAIO_COMDI_DVPIX - destination vertical pixels PXAIO_COMDI_SHPIX - source horizontal pixels? PXAIO_COMDI_SVPIX - source vertical pixels? |

QUOTE(mahadri @ Nov 28 2005, 11:28 AM) Sharp's tc6393.h has enough information to experiment. First, I'd try modifying the fill command this sounds very promising. Perhaps with the re-release of the 6000 as a windows mobile device more information will come out too. Whilst I'd love to help, I'm only running kernel 2.4 on the Guylhem ROM, sorry :-( I've also no experience at actually writing kernel modules. But, I'd be willing to give back-porting the driver to 2.4.x a shot, or even being a guinea pig if I can. If nothing else, be encouraged that there are lots of eager people waiting for faster video drivers for their 6000! Paul |

I could reverse-engineer those drivers if they implement a feature we like.QUOTE Whilst I'd love to help, I'm only running kernel 2.4 on the Guylhem ROM, sorry :-( The Sharp kernel exports an ioctl for video acceleration. I doubt any Sharp-based ROM removed this ioctl, so you can test from userspace. You just need a cross-compiler to compile tosaacc.c. It's a simple program that uses the Fill command to clear the screen to a color specified on the command line.Usage: tosaacc <color in hex> Example: tosaacc 48c0 If there's enough demand from people without cross-compilers, I can modify this program to read accelerator commands from stdin so I can distribute a binary version. It's not as nice, though, as you can't use Sharp's #defines and would have to write all commands in hex. |

Hello
By any chance, would you have the chip tech ref with details explaining the hardware acceleration? It would be great to have that working. Experimenting could take a while, but it would be great to have accel working... Video Accel is IMHO the most important thing the 6000 miss (imagine playing divx from a microdrive at 640X480 24fps on that beautiful screen !) - it could be shared between 2.4 and 2.6 kernels Email me guylhem at googlemail dot com if you want the information I have about the chip, the device, etc. Guylhem |

This is very useful for accelerating window managers, as they tend to draw the backing color, then the objects on top. The source copy would be great for moving windows, scrolling windows, scrolling the console, and drawing console characters. I found what a screen copy command (PXAIO_COMDI_SCGO) takes four arguments: PXAIO_COMDI_DSADR - an addres of a destination region (left upper corner) PXAIO_COMDI_DHPIX - a width of a region to copy PXAIO_COMDI_DVPIX - a height of a region to copy PXAIO_COMDI_SSADR - an address of a source region (upper left corner) Formula to calculate address from coordinates is Addr = 2*X+Y*960 - for VGA mode (2bytes per pixel) Has somebody else any luck with Tosa video accelerator? |

QUOTE(psycoman @ Jan 4 2005, 03:43 AM) yeap, i send a email to this guy, he will send a partial document to me. lets see  someone can try, contact Toshiba ? and some news, Wince .NET have a tc6393xb.dll, can use this for reverse engenier ? I contacted Toshiba's TAEC U.S. headquarters today to request Datasheets for the TC6393XB. I've had luck with Hitachi in the past doing this, so I'm keeping my fingers crossed. |

My first response from Toshiba is displayed below.
Looks like a possible dead end. I've sent the engineer another e-mail asking him to forward my request to someone who might be able to provide more information. Hopefully I'll hear back from him soon. QUOTE Hi John,
This is a Secured Digital Host Controller (SDHC) device which we don't sell anymore. I also don't have any datasheet of that part to share with you.

Just to note that the MSDN site has a comment about the SD/SDIO driver for this chip at
http://msdn.microsoft.com/embedded/usewine...rs/default.aspx which would be a nice addition! |

I chased this down a couple of days ago with no luck in finding the mentioned DLL. It would be usefull to have a look inside. |
