func (b Builder) WithNumMSHREntry(num int) Builder

WithNumMSHREntry sets the number of mshr entry

func (Builder) WithNumReqPerCycle

func (b Builder) WithNumReqPerCycle(n int) Builder

WithNumReqPerCycle sets the number of requests per cycle can be processed by a TLB

func (Builder) WithNumSets

func (b Builder) WithNumSets(n int) Builder

WithNumSets sets the number of sets in a TLB. Use 1 for fully associated TLBs.

func (Builder) WithNumWays

func (b Builder) WithNumWays(n int) Builder

WithNumWays sets the number of ways in a TLB. Set this field to the number of TLB entries for all the functions.

func (Builder) WithPageSize

func (b Builder) WithPageSize(n uint64) Builder

WithPageSize sets the page size that the TLB works with.

type Comp

type Comp struct {
	*sim.TickingComponent
	sim.MiddlewareHolder

	LowModule sim.RemotePort

	Sets []internal.Set
	// contains filtered or unexported fields
}

Comp is a cache(TLB) that maintains some page information.

func (*Comp) Tick

func (c *Comp) Tick() bool

type FlushReq

type FlushReq struct {
	sim.MsgMeta
	VAddr []uint64
	PID   vm.PID
}

A FlushReq asks the TLB to invalidate certain entries. It will also not block all incoming and outgoing ports

func (*FlushReq) Clone

func (r *FlushReq) Clone() sim.Msg

Clone returns cloned FlushReq with different ID

func (*FlushReq) Meta

func (r *FlushReq) Meta() *sim.MsgMeta

Meta returns the meta data associated with the message.

type FlushReqBuilder

type FlushReqBuilder struct {
	// contains filtered or unexported fields
}

FlushReqBuilder can build AT flush requests

func (FlushReqBuilder) Build

func (b FlushReqBuilder) Build() *FlushReq

Build creates a new TLBFlushReq

func (FlushReqBuilder) WithDst

func (b FlushReqBuilder) WithDst(dst sim.RemotePort) FlushReqBuilder

WithDst sets the destination of the request to build.

func (FlushReqBuilder) WithPID
