Expected data rate is up to 100k events : /second. Each even requires a sixteen bit data transfer. All parts of this : system are " under development". Eventually the data taker will be a 486/33, : but we have transferred data at 100kHz on the 486/33 using a preliminary, : DOS-based, program running in a DOS window. 100kHz!!!! Is this correct??? This works out to 10 microseconds per event - which would make it almost an order of magnitude faster than the probable OS/2 context switch time. Has anyone done realtime graphics display on an OS/2 machine? (DOS,WINOS2 or PM). What's the performance esp. with respect to timing jitter? jin meng
