Each PC host CPU running a standard image processing application on Windows 2000 or XP will fill a big image buffer up to 4 GBytes in the host memory. Then a real time subsystem running on the local bus side of the 9656 will set up requests to read data from that buffer.
Our wondering is about the fact that the reading has to be done in a deterministic manner, thus eliminating the need of big elastic buffer. When there is a request to read a given part of that buffer (ex: a line of 2Kbytes), it has to be delivered immediately with almost no latency . I understand that the 9656 may be set up as a master, but what about its priority. I do not know enough about Windows 2000 or XP to see if there is a way to to give the absolute priority to the 9656. I would like to stay with Windows 2000 or XP instead of a real time OS in order to be able to use standard image processing appplications.
Is it possible to set up the arbitration to give absolute priority to the 9656 ?
