Detailed Description

DVM Context matcher.

The matcher is responsible for gathering inputs to the same instruction based on their contexts. The matcher should forward these tokens to the scheduler once that all of the inputs for a given context are available.

The matcher utilizes (instruction, context) pairs as keys

Constructor & Destructor Documentation

def core.contextMatcher.ContextMatcher.__init__	(		self,
			core
	)

Initialize a context matcher.

Parameters

core	The runtime core that this matcher is a part of.

Member Function Documentation

def core.contextMatcher.ContextMatcher.setKey	(		self,
			inst,
			cont,
			amount
	)

Dynamically set the amount of tokens a certain instruction should receive.

Parameters

inst	The address of the instruction to set the token amount for.
cont	The context for which this amount is valid.
amount	The amount of tokens this matcher requires for this key.

def core.contextMatcher.ContextMatcher.checkKey	(		self,
			key
	)

See if a given key is already a part of the tokens we are matching.

Create an array to match these tokens if it's not.

Parameters

key	The key to check

def core.contextMatcher.ContextMatcher.updateKeyArr	(		self,
			key,
			port,
			token
	)

Update the token array for a key This method assumes that there is an array for the given key.

Parameters

key	The key to find the array we want to update.
port	The destination port of the token we want to add.
token	The token we want to add.

def core.contextMatcher.ContextMatcher.isKeyReady	(		self,
			key
	)

See if all the input tokens are present for a given key.

Parameters

key	The key to check

Returns

True if all the input tokens are present for key.

def core.contextMatcher.ContextMatcher.executeKey	(		self,
			key
	)

Add the tokens for key to the scheduler.

def core.contextMatcher.ContextMatcher.add	(		self,
			token
	)

Add a token to the matcher.

This method can be seen as the main method of the matcher as it utilizes all the other methods to define the behaviour that the matcher will use when a token is added.

Parameters

token

the token to add.
