Abstract: Systems and methods for translating cache hints between different protocols within a SoC. A requesting agent within the SoC generates a first cache hint for a transaction, and the first cache hint is compliant with a first protocol. The first cache hint can be set to a reserved encoding value as defined by the first protocol. Prior to the transaction being sent to the memory subsystem, the first cache hint is translated into a second cache hint. The memory subsystem recognizes cache hints which are compliant with a second protocol, and the second cache hint is compliant with the second protocol.
Abstract translation: 用于翻译SoC中不同协议之间的缓存提示的系统和方法。 SoC中的请求代理生成用于事务的第一高速缓存提示,并且第一高速缓存提示符合第一协议。 第一个缓存提示可以设置为第一个协议定义的保留编码值。 在将事务发送到存储器子系统之前,第一高速缓存提示被转换成第二高速缓存提示。 存储器子系统识别符合第二协议的高速缓存提示,并且第二高速缓存提示符合第二协议。
