Detailed Description

A ScoreboardView is a view into the master Scoreboard for operand readiness.

Used by the Schedulers/Execution units, the view represents that Scheduler/Execution unit's view into readiness of a rename in the machine.

Constructor & Destructor Documentation

ScoreboardView()

sparta::ScoreboardView::ScoreboardView	(	const std::string &	unit_name,
		const std::string &	scoreboard_type,
		sparta::TreeNode *	node )

Create a ScoreboardView.

Parameters

unit_name	The unit name that's creating/receiving SB updates
scoreboard_type	The type of master Scoreboard to connect to
The	sparta::TreeNode to search for the scoreboard_type

Member Function Documentation

clearCallbacks()

void sparta::ScoreboardView::clearCallbacks

(

const Scoreboard::InstID

inst_id

)

On a flush any registered callback needs to be "forgotten".

Parameters

unique_id

The unique ID to find and flush

Clears ready callbacks

getName()

std::string sparta::ScoreboardView::getName ( ) const

inline

Get the name of this view.

Returns

Name of the view

Definition at line 265 of file Scoreboard.hpp.

getType()

std::string sparta::ScoreboardView::getType ( ) const

inline

Get the scoreboard type identifier.

Returns

Name string for the scoreboard type

Definition at line 257 of file Scoreboard.hpp.

isSet()

bool sparta::ScoreboardView::isSet ( const Scoreboard::RegisterBitMask & bits ) const

inline

See if the given bits are set.

Parameters

bits	Bits to check

Returns

A boolean of result

Definition at line 242 of file Scoreboard.hpp.

registerReadyCallback()

void sparta::ScoreboardView::registerReadyCallback	(	const Scoreboard::RegisterBitMask &	bits,
		const Scoreboard::InstID	inst_id,
		const ReadinessCallback &	callback )

Register a ready callback to be called when the bits are ready.

Parameters

bits	RegisterBitMask of bits to masked to determine ready
callback	The handler to call; boolean argument + bits being set

Expected callback signature:

void func(const Scoreboard::RegisterBitMask & bits);

After a scoreboard update and the new bits are a match for the registered bits, the callback will be called and cleared from the Scoreboard.

setReady()

void sparta::ScoreboardView::setReady

(

const Scoreboard::RegisterBitMask &

bits

)

Set the given bits as ready in the Scoreboard.

Parameters

bits	Bits to propagate
