LOW POWER ENTRY IN A SHARED MEMORY LINK

摘要

Data is sent to correspond to a load/store-type operation associated with shared memory over a link according to a memory access link protocol and the memory access link protocol is to be overlaid on another, different link protocol. A request is sent to enter a low power state, where the request is to include a data value encoded in a field of a token, the token is to indicate a start of packet data and is to further indicate whether subsequent data to be sent after the token is to include data according to one of the other link protocol and the memory access link protocol.

1. An apparatus comprising:
a transmitter to send data to correspond to a load/store-type operation associated with shared memory, wherein the data is to be sent over a link according to a memory access link protocol and the memory access link protocol is to be overlaid on another, different link protocol; power management logic to send a request to enter a low power state, wherein the request is to comprise a data value encoded in a field of a token, the token is to indicate a start of packet data and is to further indicate whether subsequent data to be sent after the token is to comprise data according to one of the other link protocol and the memory access link protocol.
