         well, if throiughput is a problem            01/01/70 00:00      
         VGA vs. NTSC (OK, PAL)            01/01/70 00:00      
            especially on CRTs?            01/01/70 00:00      
               flicker            01/01/70 00:00      
                  Distortion            01/01/70 00:00      
                     until today...            01/01/70 00:00      
                        Logical Processors            01/01/70 00:00      
                           not likely ...            01/01/70 00:00      
                              sure, but what problem is that            01/01/70 00:00      
               It's the demand for precise timing            01/01/70 00:00      
                  Monochrome?            01/01/70 00:00      
                     He may be a bit misguided            01/01/70 00:00      
                  Ive used an spi interface            01/01/70 00:00      
                     This is the arbitary display overlay jobby            01/01/70 00:00      
      A NICE VIDEO GENERATING AND PROCESSING EXAMPLE!!            01/01/70 00:00      
         Is it VGA?            01/01/70 00:00      
   Video Buffer            01/01/70 00:00      
      and a "video DAC"            01/01/70 00:00      
         Well there are ways and ways ....            01/01/70 00:00      
            but VGA is twice as fast            01/01/70 00:00      
               VGA Pixel rate is faster but ...            01/01/70 00:00      
                  If the MCU can\'t do it all ...            01/01/70 00:00      
                     how about this one            01/01/70 00:00      
                        "stuffer"            01/01/70 00:00      
                           it'd better be a really cheap MCU            01/01/70 00:00      
                              why?            01/01/70 00:00      
                        the guy who pays for it would notice.            01/01/70 00:00      
                           why?            01/01/70 00:00      
                              The extra MCU contributes nothing. Why use it?            01/01/70 00:00      
                                 because            01/01/70 00:00      
                                    TEXT => Pixels = character generator            01/01/70 00:00      
                                       sure, but            01/01/70 00:00      
                                          True, but only sometimes ...            01/01/70 00:00      
                                             HUH?            01/01/70 00:00      
                                                so ... which MCU has those built in?            01/01/70 00:00      
                                                   those?            01/01/70 00:00      
                                                      Here's what "those" are ...            01/01/70 00:00

                        What do you mean, Phillip?            01/01/70 00:00      
                           A notion not to radical or heretical ...            01/01/70 00:00

      Like the vhdl that you'll find            01/01/70 00:00      
         Here's an ARM7 Driving a VGA Display direct            01/01/70 00:00      
   75 Ohm?            01/01/70 00:00
