Abstract:
Methods and apparatuses relating to consistency in an accelerator are described. In one embodiment, request address file (RAF) circuits are coupled to a spatial array by a first network, a memory is coupled to the RAF circuits by a second network, a RAF circuit is to not issue, into the second network, a request to the memory marked with a program order dependency on a previous request until receiving a first token generated by completion of the previous request to the memory by another RAF circuit, and a second RAF circuit is to not issue, into the second network, a second request to the memory marked with a program order dependency on a first request until receiving a second token sent by a first RAF circuit when a predetermined time period has lapsed since the first request was issued by the first RAF circuit into the second network.
