Class RawExecutionCode

java.lang.Object
  extended by at.dms.util.Utils
      extended by at.dms.kjc.spacedynamic.RawExecutionCode
All Implemented Interfaces:
Constants, DeepCloneable, FlatVisitor, Serializable
public class RawExecutionCode
extends Utils
implements FlatVisitor, Constants

This pass creates the SIR necessary for each filter of the StreamGraph to execute on Raw. It creates SIR to handle the communication for filters by possibly creating a buffer or a circular buffer (see BufferedCommmunication.java) or no buffer (See DirectionCommunication.java).

Field Detail

INLINE_WORK

public static boolean INLINE_WORK
if this is true, then inline the work function calls (for each of the code generation schemes), if work remains a function and is called.

fields for the var names we introduce **

recvBufferSize

public static String recvBufferSize

recvBufferBits

public static String recvBufferBits

sendBuffer

public static String sendBuffer

sendBufferIndex

public static String sendBufferIndex

rateMatchSendMethod

initSchedFunction

public static String initSchedFunction

steadySchedFunction

public static String steadySchedFunction

receiveMethod

public static String receiveMethod

structReceivePrefix

public static String structReceivePrefix

structReceivePrefixStatic

public static String structReceivePrefixStatic

structReceivePrefixDynamic

public static String structReceivePrefixDynamic

popDynamic

public static String popDynamic
the name of the pop mehtod for each filter when the filter has dynamic input and we are not inlining

peekDynamic

public static String peekDynamic
the name of the peek method for each filter when the filter has dynamic input and we are not inlining the method

arrayReceiveMethod

public static String arrayReceiveMethod

rawMain

public static String rawMain
Constructor Detail

RawExecutionCode

public RawExecutionCode(SpdStaticStreamGraph ssg)
Method Detail

doit

public static void doit(SpdStreamGraph streamGraph)

visitNode

public void visitNode(FlatNode node)
Description copied from interface: FlatVisitor
The visitor must define this method that will be called once on each FlatNode that is down stream of the accepting node.

Specified by:
visitNode in interface FlatVisitor
Parameters:
node - the node that is being currently visited.

calculateItems

public void calculateItems(SIRFilter filter)

makeForLoop

public static JStatement makeForLoop(JStatement body,
                                     JLocalVariable var,
                                     JExpression count)
Returns a for loop that uses field 
var
to count 
count
times with the body of the loop being 
body
. If count is non-positive, just returns empty (!not legal in the general case)

executeWorkFunction

public static JBlock executeWorkFunction(SIRFilter filter)
This method is used by the various code generation schemes to return the statement that executes a work function call. If we are inlining work, it will return the cloned work body block, otherwise it will return a method call for the work function. Return a block so that we can add statements to the block if necessary.

getBottomPeek

public int getBottomPeek()

getInitFire

public int getInitFire()

getRemaining

public int getRemaining()
