Typedef Documentation

Addr

typedef uint64_t Addr

Address type This will probably be moved somewhere else in the near future.

This should be at least as big as the biggest address width in use in the system, which will probably be 64 bits.

Definition at line 142 of file types.hh.

ContextID

typedef int ContextID

Globally unique thread context ID.

Definition at line 231 of file types.hh.

Counter

typedef int64_t Counter

Statistics counter type.

All counters are of 64-bit values.

Not much excuse for not using a 64-bit integer here, but if you're desperate and only run short simulations you could make this 32 bits.

Definition at line 58 of file types.hh.

Fault

typedef std::shared_ptr<FaultBase> Fault

Definition at line 240 of file types.hh.

MicroPC

typedef uint16_t MicroPC

Definition at line 144 of file types.hh.

PortID

typedef int16_t PortID

Port index/ID type, and a symbolic name for an invalid port id.

Definition at line 237 of file types.hh.

RegVal

typedef uint64_t RegVal

Definition at line 168 of file types.hh.

ThreadID

typedef int16_t ThreadID

Thread index/ID type.

Definition at line 227 of file types.hh.

Tick

typedef uint64_t Tick

Tick count type.
