Detailed Description

Thread class manages thread properties and execution, including program counters, priorities, and registers, and provides methods for reading, writing, and adjusting these attributes.

Public Functions Documentation

function AdvancePC

Increase program counter.

void simtix::Thread::AdvancePC ()

PC = PC + 4.

function LowerFunctPriority

Lower function priority of the thread.

void simtix::Thread::LowerFunctPriority ()

Check if thread function priority is equal to 0. If it is not, lower the function priority.

function LowerPriority

Lower priority of the thread.

void simtix::Thread::LowerPriority ()

Check if thread priority is equal to 0. If it is not, lower the priority.

function RaiseFunctPriority

Raise function priority of the thread.

void simtix::Thread::RaiseFunctPriority ()

Check if thread function priority is equal to <max_priority_f_level_ - 1>. If it is not, raise the function priority.

function RaisePriority

Raise priority of the thread.

void simtix::Thread::RaisePriority ()

Check if thread priority is equal to <max_priority_level_ - 1>. If it is not, raise the priority.

function ReadCSR

Read thread CSRs.

int32_t simtix::Thread::ReadCSR (
    uint16_t addr,
    uint64_t * data
)

Parameters:

addr Address of CSR.
data Pointer to store the data.

Returns:

0 on success, -1 on fail, the CSR is undefined in thread level and other levels.

function Reset

Reset pc, priority and regfile to 0.

void simtix::Thread::Reset ()

function ResetPC

Reset program counter.

void simtix::Thread::ResetPC ()

PC = 0.

function ResetPriority

Reset priority.

void simtix::Thread::ResetPriority ()

Priority = 0.

function SetPriority

Set priority.

void simtix::Thread::SetPriority (
    uint32_t set_priority
)

Set priority to a specific value.

function Thread

Constructor of Thread .

explicit simtix::Thread::Thread (
    Warp * warp,
    uint32_t tid,
    const ArchParam & p=kDefaultArchParam
)

Parameters:

warp The warp which thread belongs to.
tid Thread id.
p Architecture parameter.

function WriteCSR

Write thread CSRs.

int32_t simtix::Thread::WriteCSR (
    uint16_t addr,
    uint64_t data
)

Parameters:

addr Address of CSR.
data Data to write in.

Returns:

0 on success, -1 on fail, the CSR is undefined or cannot write read-only CSR.
