Detailed Description

Represents both memory requests and responses.

Flag type

Request ID type

Commands and responses possible with a Request object.

Enumerator:

Read	Issue a Read from Memory
Write	Issue a Write to Memory
ReadResp	Response from Memory to a Read
WriteResp	Response from Memory to a Write

Flags to specify conditions on a Request.

Enumerator:

F_NONCACHEABLE	This request should not be cached
F_LOCKED	This request should be locked. A LOCKED read should be soon followed by a LOCKED write (to unlock)
