Types

type BasicFetch

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

BasicFetch retrieves instruction bits for the current PC.

func NewBasicFetch

func NewBasicFetch(initPC uint64, xlen riscv.Xlen) BasicFetch

NewBasicFetch returns a new instance of BasicFetch.

func (*BasicFetch) GetBitsJmp

func (b *BasicFetch) GetBitsJmp(target uint64) protocol.FetchRsp

GetBitsJmp returns the instruction word at the passed target PC.

func (*BasicFetch) GetBitsNPC

func (b *BasicFetch) GetBitsNPC() protocol.FetchRsp

GetBitsNPC returns the instruction word at the next stored PC.

func (*BasicFetch) Populate

func (b *BasicFetch) Populate(addr uint64, data [memory.RowBytes]byte)

Populate fills a cache line in the ICache.

func (*BasicFetch) String

func (b *BasicFetch) String() string

String returns the module current state.
