 A couple of notes: Unlike previous machines, there are just too many
 resolutions to give each resolution a name. Therefore, I will do my best
 to describe what the resolution is and which monitor it is on.

 - NOTE: TV and a Color Monitor are the same.. by Color Monitor, I am
   talking about the standard SC1224. By VGA, I mean a standard VGA
   Monitor.

  256 color, interlace, TV:      640x400,  256 colors, 8 planes
 True color, interlace, TV:      640x400,  true color

    2 color, normal, VGA:        640x480,    2 colors, 1 plane
    4 color, normal, VGA:        640x480,    4 colors, 2 planes

   16 color, line-doubling, VGA: 640x240,   16 colors, 4 planes
  256 color, line-doubling, VGA: 640x240,  256 colors, 8 planes

and lastly.. there are compability modes for ST Low, ST Medium, and ST
High on both VGA monitors and SC1224 monitors. (On a color monitor, ST
High is achieved by using the interlace mode).

Also, the ST Monochrome monitor (the SM124) will work with Falcon030 as
well. However, it only supports one resolution: ST High Resolution.

All modes on a TV can be overscanned.  This means multiplying the X and Y
resolution by 1.2.  For  example,  modes  with  320  pixels of horizontal
resolution (X res) will  become  384  pixels  across,  and modes with 640
pixels will become 768  across.  Overscanning  is  done  in  the  X and Y
resolution. You can't  do  them  independently.  Special  Note:  On a VGA
monitor, overscan is "faked".. since the  video hardware doesn't have the
capability to do overscan on  a  VGA  monitor,  we  made  it so that if a
overscan mode is set on  a  VGA  monitor,  you  still see the normal size
screen, but the screen is  a  window  onto  the bigger overscanned image.
Make sense? We did this for compatibility. This way if a game that has an
overscanned startup picture can use the same pic on both the VGA  monitor
and the TV monitor. Pretty cool, eh? <grin>

BTW.. Overscan can NOT be set from  the desktop. The AES and Desktop will
work just fine with  it,  but  because  you  can't  see  the parts of the
screen, we thought  that  that  option  shouldn't  be  available from the
desktop. We don't want to  confuse  people.  However, Overscan can be set
using a new XBIOS call (Vsetmode()).. so it is still available.

I hope I haven't made  any  mistakes.  I  triple-checked this document in
search of errors and I couldn't find  any.  If  you do find some, send me
Email on GEnie (to TOWNS) or CIS (70007,1135) and let me know.

P.S. Anyone who would like to reprint this message, please do so!
     The smaller the number of times I have to type that message, the
     more my fingers will thank you! ;-)

     After looking at this one more time.. one point to clear up: By
     saying SC1224 Color Monitor, I mean any Color Monitor that Atari
     have manufactured for the ST/Mega/STE/MegaSTE computers. Clear
     as mud? ;-)

I found this file on the local ATARI Company's BBS : (original in Dutch)

This article is written by Wilfred  Kilwinger (Support Manager) for Atari
Briefing, the newsletter  by  Atari  (Benelux)  B.V.  for  the Atari user
groups. It was specifically  stated  that  it could be reproduced. I have
translated it in English with the  assumption that an English translation
would be considered the same as the original.

The original also contained  a  description  of  all  the features of the
Falcon
which have been reproduced here a zillion  of  times so I did not include
these.

Atari custom chips

VIDEL

The VIDEL takes care  of  the  video  functions  of  the system including
overscan, overlay mode and true color graphics.

COMBEL

The COMBEL is  the  system  manager  of  the  Atari  Falcon030. This chip
controls all system functions. Also the BLITTER is built in in this chip.

SDMA

The SDMA is the Sound DMA and controls the sound part. We have built in a
unique matrix switch function in  this  chip  (more details in the second
part)

KEYBOARD PROCESSOR

The keyboard processor has been  improved  and  is  now also suitable for
high resolution mice.

Besides the above  custom  chips  the  Atari  Falcon030  has  a number of
standard  chips  like  the  Motorola  68030   and   56001   DSP.  Another
important chip is the CODEC in which the  16 bit AD and DA converters are
located.

Video modes

As you can see in the survey of Operating System calls the video hardware
is complete software  controllable.  The  following  combinations  can be
chosen:

Mode      Resolution  Bit planes  Colors  Palette

ST LOW     320x200       4           16     4096
ST MED     640x200       2            4     4096
ST HIGH    640x400       1            2     4096

True Color 640x480       8          256   262144
           320x200     15bpp      32768     N/A

The last mode asks for some  explanation.  Here there is no color palette
but 15 bits  per  pixel  to  describe  the  pixel  itself.  The format is
RRRRRGGGGGXBBBBB. VDI supports this mode thus programs that have not been
written for this mode  specifically  can  use  it  nevertheless. X is the
overlay  bit  and  can  be  used  for  video titling and special effects.

          320x200     16bpp      65         N/A

This mode is called the slideshow mode,  is not supported by the VDI, you
are on you own. X is an extra green bit.


True Color in 640x480 is  not  possible  because  of the bandwidth of VGA
monitors.

Mode      Resolution Bit planes   Colors    Palette

Video    200 of 400

With Video we mean the  Atari  SC-monitors,  the  TV modulator and/or the
composite video output.

All modes can be genlocked.  With  adaptors  we convert the 15-pole video
bus to thee standard Atari or VGA connections.

Matrix coupling

To make the system performance  in  the  audio  part  as good as possible
Atari designed a miniature 'telephone  exchange'  that can easily connect
the source devices to the receiving devices.  Also it is possible to make
more than one connection at a time.

VIDEO SETMODE

int setmode( int modecode );

The setmode( int modecode ) call is  used to place the Falcon/030 SHIFTER
into a specific mode. A bit-encoded value (called a "modecode") is passed
to setmode() to set the  mode,  setmode()  returns the previous mode that
was set.

To help make the building of modecode values easier, here is a table of
defines:

        #define VERTFLAG        0x100
        #define STMODES         0x80
        #define OVERSCAN        0x40
        #define PAL             0x20
        #define VGA             0x10
        #define TV              0x0

        #define COL80           0x08
        #define COL40           0x0
        #define NUMCOLS         7

        #define BPS16           4
        #define BPS8            3
        #define BPS4            2
        #define BPS2            1
        #define BPS1            0

Using these defines, you can build a modecode for any possible mode.
For example:

        For True Color Overscan:
        modecode = OVERSCAN|COL40|BPS16;

        For ST Medium Compatibility mode on a Color Monitor/TV:
        modecode = STMODES|COL80|BPS2;

        For ST Low Compatibility mode in PAL on a Color Monitor/TV:
        modecode = STMODES|PAL|COL80|BPS2;

        For 256 color, 80 column mode on a VGA monitor:
        modecode = VGA|COL80|BPS8;

If you have a modecode and wish to  know  how many bits per pixel it has,
use the following:

        if( modecode & NUMCOLS ) == BPS16 )
                do_something_cool();    /* You have true color mode */

The setmode() call will return  the  previous  modecode set. You must use
this value to get back to whatever mode  you were in before you made your
setmode call.


int mon_type(void)

The mon_type() function will return the kind of monitor that is currently
in use. Here are the possible return values:

        0 = ST monochrome monitor
        1 = ST color monitor
        2 = VGA monitor
        3 = Television.


void ext_sync( int flag )

This function sets or clears external sync. If flag is set, external sync
is enabled. If flag is clear, then internal sync is used.


SOUND-calls

locksnd();
Used as a semaphore to lock the sound system. From other applications.

unlocksnd();
Used to release the sound system for other applications to use.

soundcmd(mode,data);
This command is used to get or set the following sound parameters.
If a negative number is used as the input then the current setting us
returned.

MODE    OPERATION       MEANING

O       LTATTEN Sets the current left channel output

1       RTATTEN Sets the current right channel output

2       LTGAIN  Sets the current left channel input gain.

3       RTGAIN  Sets the current right channel input gain.

4       ADDERIN Set the output of the 16 bit signed adder to
                receive it's input from the ADC, Matrix or
                both.

5       ADCINPUT        Set the input the the ADC. The input can either
                        be the left and right channel of the PSG or the
                        left and right channel of the microphone.

6       SETPRESCALE     Used for compatibility. This prescale value
                        is used when the DEVCONNECT() internal
                        prescale value is set to zero.


setbuffer(reg,begaddr,endaddr);
This function is used to  set  the  play  or  record buffers. REG selects
playback or record, while begaddr  and  endaddr are the buffers beginning
and ending locations.

        (int)   reg             - (0) Sets playback registers.
                                - (1) Sets record registers.
        (long)  begaddr - Sets the beginning address of the buffer.
        (long)  endaddr - Sets the ending address of the buffer.

setmode(mode);
This function is used to set record or playback mode. The modes are as
follows:

MODE            OPERATION
(int)   0      8 Bit Stereo
(int)   1      16 Bit Stereo
(int)   2      8 Bit Mono

settracks(playtracks,rectracks);
This function is used to sets the number of record or playback tracks.

setmontracks(montrack);
This function is used to set the output of the internal speaker to one of
the four tracks currently playing.  The  internal speaker is only capable
of outputting ONE track at a time.

setinterrupt(src_inter,cause);
This function is used to set which  interrupt  will occur at the end of a
frame. If the frame repeat bit is on, this interrupt is used to allow for
double buffering the playing or  recording  of sound. Interrupts can come
from TimerA or the MFP i7.

buffoper(mode);
This function is used to  control  the  operation  of  the play or record
buffers in the sound system. The input  to  this function is a bitmap. If
mode is set t0 -1 then the current status of the buffer operation bits is
returned.

NOTE:   The sound system contains a  32 byte FIFO. When transferring data
to the record buffer, software  MUST  check  to  see if the record enable
(RE) bit was cleared by the  hardware.  If  the  bit was cleared then the
FIFO is flushed, if not then software must flush the FIFO by clearing the
record enable (RE) bit.

dsptristate(dspxmit,dsprec);
This function is used to tristate the DSP from the data matrix.

gpio(mode,data);
This is used to  communicate  over  the  General  Purpose  I/O on the DSP
connector. Only the low order three bits are used. The rest are reserved.
This call, depending on the mode, can be used to set the direction of the
I/O bits, read the bits, or write the bits.

devconnect(src,dst,srcclk,prescale,protocol);
This function is used to attach a source device to any of the destination
devices in the matrix. Given a source  device, this call will attach that
one source device to one  or  all  of  the destination devices. This call
also sets up the source clock and prescaler, protocol and protocol source
if used.

sndstatus(reset);
This function gets the current status of the codec.

buffptr(pointer);
This function returns the current  position  of  the play and record data
buffer  pointers.  These  pointers  indicate  where  the  data  is  being
read/written within the buffers themselves. This function is also used to
determine how much  data  has  been  written  to  the  record buffer. See
buffoper().


The above is not yet complete. Atari has also routines for JPEG and andio
conversion.

Things which the  56001  should  be  useful  for  include  software sound
synthesis & matrix*vector multiplication (the basis of 3D vector games).

If the DSP DMA is implemented  right  (does  anyone have a programmer eye
view of this yet?) is should be  possible  to use it as an extremely fast
graphics processor for polygons/phong  shading/texture  mapping (I wonder
if anyone will bother to write  an  "Ultima Underworld" type game for the
Falcon?). I worry about this though - the DSP is 24 bits and the 68030 is
32 bits so there's plenty of room for Atari to screw up...

For anyone who hasn't seen  the  latest  AEO,  the Falcon appears to have
been design as a 24 bit  computer,  partly to maintain compatibility with
existing software. This doesn't mean third  party boards etc can't extend
that, but it explains the 14  meg  memory  limit. The other captures from
Jim Allen posts to GEnie say that  the  Falcon  chips all seem to talk at
16mhz. Another poster mentioned here  that  there's  an 8bit processor to
dsp channel, I guess for uploading code into the dsp, though I don't know
if that means you can't tell  the  dsp  to  load  a program from a memory
location itself, which would be faster, I'd guess.

Motorola says the top speed  the  56001  is  clocked  at is 33mhz, so the
AD/DA converters must be the parts clocked at 50mhz.

clint@artech.UUCP (Clinton Keith) writes:

The adc/dac channel is driven off  the  DMA  clock, which is driven off a
sub-divided horizontal scan rate.  The 525  scan line rate sub-divided by
12, 24, 48 and 96 give the 6250,  12500, 25000 and 50000 bytes per second
DMA/CODEC rate.  This is the same as the STE/TT.

In the very techie "test" of the Falcon in the German C'T you can read a
different story:

"[external/internal clock, prescale 4-24 or  128].  Internally there is a
27.175MHz clock to select the STe  known sampling rates of 12.5KHz, 25KHz
and 50KHz, or 32MHz in  order  to  use  the  full bandwidth of the memory
transfer, with an sampling rate of  62.5KHz on eight 16bit channels. This
is also the upper limit for the external clock."

(If the above doesn't  make  any  sense  then  it  is probably because my
German is even worse than my English)
