          edu.cmu.emulator.controlComm.SetTimedScaleMessage

public class SetTimedScaleMessage
extends TupleMessage

Sends scaling updates to the auxfpga with timing information that allows the precise time that the updates occur to be controlled. Each message consists of several scale sets. Each set occurs at a specified offset relative to a reference time contained in this message. This message also contains the current system time so that the auxfpga can synchronize its clock to the system clock.

Constructor Detail

SetTimedScaleMessage

public SetTimedScaleMessage(int numTuples,
                            int sysTime,
                            int startTime)

Parameters:

sysTime - - the current system time (e.g. EmuSynch.curTimeMillis() cast to an int

startTime - - the reference time for all scaling sets contained in this message. usually, this is the time of the first scaling update.
