you can pool 240*32 generators on the device, at any given moment only 240 are executed. to compute the your performance you would have to measure how long a single A5/1 computation takes and multiply accordingly. Since you can get this number simply by running the program, why bother? 240 cores should give you around 150million A5/1 per second at standard 600mhz.
