Parameters

group_num	Group number of register to inspect
group_idx	Group index of register to inspect

group_idx	Index within the given group. Corresponds to sparta::Register::Definition::group_idx

Returns: A non-nullptr Register. Guaranteed to return or throw

Exceptions

SpartaExeption if the register cannot be found.

Here is the call graph for this function:

◆ getRegisterProxy()

RegisterProxy & sparta::RegisterSet::getRegisterProxy ( const std::string & name )

inline

Retrieves a register proxy based on the given name. RegisterProxies are an indirection layer that direct acccesses to registers in various banks depending on the state of the simulator that owns them.

Parameters

name	Any valid Register name or the name of a Registered defined as a proxy (see Register::Definition)

Note: Using a RegisterProxy add slight overhead to register accesses and should generally be a debugging/ui/verification tool

Returns: RegisterProxy reference owned by this RegisterSet. A RegisterProxy returned will remain valid until this RegisterSet is destructed. It is safe to take the address of this result and store it

Definition at line 674 of file RegisterSet.hpp.

Here is the call graph for this function:

◆ getRegisters()

const RegisterVector & sparta::RegisterSet::getRegisters ( ) const

inline

Gets the vector of Registers contained by this set.

Note: There is no non-const version of this method. Modifying this vector externally should never be allowed

Definition at line 630 of file RegisterSet.hpp.

◆ lookupRegister() [1/2]

RegisterBase * sparta::RegisterSet::lookupRegister	(	RegisterBase::group_num_type	group_num,
		RegisterBase::group_idx_type	group_idx
	)

inline

Quickly looks up a register by its number and index with bounds checking.

Parameters

group_num	Group identifier number. Corresponds to sparta::Register::Definition::group_num
group_idx	Index within the given group. Corresponds to sparta::Register::Definition::group_idx

Returns: regsiter requested if found, otherwise a nullptr if the group number and index do not correspond to an actual register but happen to be present in the internal lookup table. If parameters do not correspond to an actual register in this set, may also cause a segfault. Therefore, the result can (and should) be used without null-checking.

Warning: For performance, does not perform any bounds checking. Can segfault if invalid parameters are given. Should be used in conjunction with canLookupRegister (at simulation startup) to ensure that lookups will succeed for all registers that will be accessed.

Exceptions

Does	not throw. May simply segfault.

Note: Whether the result of this function will be a valid register

The expected usage of this method is to use the result without null checking since this method can cause fatal errors.

rset->lookupRegister(gnum,gidx)->something()

At simulator startup, the presence of all required registers can be queried once with sparta::RegisterSet::canLookupRegister to ensure that any register which may be be accessed during the course of simulation will be available through this method.

		RegisterBase::group_idx_type	group_idx,
		RegisterBase::bank_idx_type	bank_idx
	)

inline

Alternate lookupRegister with additional bank field.

Note: Separately defined so that lookup can be implemented differently for banked and non-banked usage if required without a performance penalty from the extra parameter

Definition at line 769 of file RegisterSet.hpp.

◆ reset()

void sparta::RegisterSet::reset ( )

inline

Reset all registers in this set to default values.

Definition at line 576 of file RegisterSet.hpp.

◆ setMinimumBankIndex()

void sparta::RegisterSet::setMinimumBankIndex ( RegisterBase::bank_idx_type min_idx )

inline

Sets the minimum bank index for this register set, overriding the default of Register::BANK_IDX_DEFAULT.

Parameters

min_idx Minimum bank index to be accessible. This is an index, so the minimum number of banks required will be min_idx+1

Note: This can only increase the number of banks currently represented

This ensures that a minimum number of banks are instantiated in this RegisterSet. Register set definitions can cause more banks to be instantiated though.

This is required if banked operation is required, but for som reason all registers in the RegisterSet are unbanked (available in every bank) because all of their definitions' bank_membership list are empty.

Definition at line 599 of file RegisterSet.hpp.

Here is the call graph for this function:

◆ stringize()

virtual std::string sparta::RegisterSet::stringize ( bool pretty = false ) const

inlineoverridevirtual

Create a string representation of this node.

Parameters

pretty Print a more verbose, multi-line representaiton (if available).

Returns: string representation of this node "<" <location> ">"

Note: this representation contains some basic information and is not meant for deserialization.

Subclasses should override this with representations appropriate for their type.

Reimplemented from sparta::TreeNode.
