Cache configured to log addresses of high-availability data via a non-blocking channel

摘要

A technique for operating a data processing system includes determining whether a cache line that is to be victimized from a cache includes high availability (HA) data that has not been logged. In response determining that the cache line that is to be victimized from the cache includes HA data that has not been logged, an address for the HA data is written to an HA dirty address data structure, e.g., a dirty address table (DAT), in a first memory via a first non-blocking channel. The cache line that is victimized from the cache is written to a second memory via a second non-blocking channel.

1. A data processing system, comprising:
a producer core; and a producer cache coupled to the producer core, wherein the producer cache is configured to:
determine whether a cache line that is to be victimized from the producer cache includes high availability (HA) data that has not been logged, wherein the producer cache includes one or more cache lines that do not include HA data;in response determining that the cache line that is to be victimized from the producer cache includes HA data that has not been logged, writing an address for the HA data to an HA dirty address data structure in a first memory via a first non-blocking channel; andwriting the cache line that is victimized from the producer cache to a second memory via a second non-blocking channel.
