I need to move a large burst (~500 Mbytes) of serial (not ASYNC-formatted) data that arrives at a steady synchronous rate of ~10 Mbits/second into a PC from an 085x-based piece of hardware. These bursts cannot be interrupted, but are quite infrequent (~ one such burst per hour).


10 Mb/s is a puny data rate. I've got a Medium Camera Link set-up here that's doing 320 MB/s (that's capital B for bytes, four bytes per clock at 80 MHz). SCSI 320 can do that, too.

USB is clearly ruled out because of its intermittent interaction with Windows.


LOL, that's ridiculous. Use isochronous transfers using high-speed USB 2.0. Iso transfers guarantee bandwidth.

How would you guys do it?            01/01/70 00:00      
   Not sure Windows can do it            01/01/70 00:00      
      High-speed USB and a buffer            01/01/70 00:00      
         USB for DOS?            01/01/70 00:00      
            once you remove all the potential source...            01/01/70 00:00      
               Latency is the problem - not the transfer rate            01/01/70 00:00      
                  You're right ... it's the latency            01/01/70 00:00      
                     Just one machine?            01/01/70 00:00      
                        Nope ... it seems that all Windows boxes are slow            01/01/70 00:00      
                           The hw shouldn't be hobbled            01/01/70 00:00      
               I'd love to use USB, but lack faith in the OS            01/01/70 00:00      
                  Try other PC or deactivate devices if you get lockups            01/01/70 00:00      
                     this all puzzles me            01/01/70 00:00      
                        1.5GB/minute reasonable for backup to USB2 disk            01/01/70 00:00      
   lantronix xport ??            01/01/70 00:00      
      How would that help?            01/01/70 00:00      
   with PCI or ISA with dma            01/01/70 00:00      
      gigabit ethernet?            01/01/70 00:00      
         Gbit normally overkill            01/01/70 00:00      
         I've considered that ... I don't like the overhead            01/01/70 00:00      
            economical ways            01/01/70 00:00      
               Do those work with DOS?            01/01/70 00:00      
                  any of OS will do...            01/01/70 00:00      
            100Mbit Ethernet on 8051            01/01/70 00:00      
   Firewire will do it            01/01/70 00:00      
      That's probably too much overhead!            01/01/70 00:00      
   LVDS to PCI card            01/01/70 00:00      
   re: how            01/01/70 00:00      
      It's not that simple            01/01/70 00:00      
         ESCC is the best option            01/01/70 00:00      
         do you REALLY think            01/01/70 00:00      
            Shouldn't be a problem            01/01/70 00:00
