Class DSPConfiguration

java.lang.Object
  edu.cmu.emulator.dsp.DSPConfiguration

All Implemented Interfaces:

Comparator

Direct Known Subclasses:

PathBasedDSPConfiguration

public abstract class DSPConfiguration
extends Object
implements Comparator

DSPConfiguration stores information about the current configuration of the FPGA. This class must be concretely represented by subclasses that contain information about the specific configuration of the FPGA. For instance, it may store the number of signal paths currently supported as well as the delay path depth for each path, etc. Currently the only assumed commonality is that a given number of output ports exist. Part of the idea here is to try to store all configuration specific information in one place. So if we change to having configurations with shared signal paths and such the effects on the rest of the code will be reduced.
