MoveData

// Constructor
SST::Interfaces::StandardMem::MoveData(Addr pSrcAddr, Addr pDstAddr, uint64_t size, bool posted = false,
    flags_t flags = 0, Addr vSrcAddr = 0, Addr vDstAddr = 0, Addr iPtr = 0, uint32_t tid = 0);

Response Type StandardMem::WriteResp  
Needs Response Depends on the value of the posted variable

The StandardMem::MoveData request class defines a request to move and/or copy data from a source address to a destination address. An example use case would be moving data into a scratchpad by copying data from a source memory address to a destination scratchpad address. Whether the data is migrated (moved) or copied is up to the underlying memory system implementation. An interface that receives this request should return a response containing the requested data if the posted field is false. Fields for both virtual and physical addresses are available, the interpretation of those fields is up to the underlying memory system model. A physical address is however required in the constructor for both the source and destination locations.

Member variables​

Including those inherited from the StandardMem::Request base class, StandardMem::MoveData includes the following member variables.

  • id (id_t) A request or response identifier. A request and its response contain the same identifier.
  • flags (flags_t) A 32-bit vector indicating any special flags added to the request
  • pSrcAddr (Addr) The physical starting address for the bytes to move
  • pDstAddr (Addr) The physical starting address of where to move the bytes to
  • vSrcAddr (Addr) The virtual (if any) starting address for the bytes to move
  • vAddr (Addr) The virtual (if any) starting address of where to move the bytes to
  • size (uint64_t) The number of bytes to read
  • posted (bool) Whether the write is posted (does not require a response)
  • iPtr (Addr) An instruction pointer. This is optional metadata.
  • tid (uint32_t) An optional thread ID, can be used by memory systems if needed

Virtual functions inherited from the Request base class​

makeResponse​

Request* makeResponse();

Creates a WriteResp initialized as a response to this MoveData request. Initializes the data field in the response to be size bytes with value 0.

needsResponse​

bool needsResponse();

Returns true.

convert​

SST::Event* convert(RequestConverter* converter);

Invokes convert() on the supplied converter visitor class to return an SST::Event in an implementation-specific format.

handle​

virtual void handle(RequestHandler* handler) =0;

Invokes handle() on the supplied handler visitor class to handle the event according to type.

getString​

virtual std::string getString() =0;

Returns a formatted string listing all fields of the MoveData.

Example Output:
ID: 12, Type: MoveData, Flags: [], SrcPhysAddr: 0x141a40, SrcVirtAddr: 0x0, DstPhysAddr: 0x5b00, DstVirtAddr: 0x0, Size: 32, Posted: F, InstPtr: 0x0, ThreadID: 0
