Abstract:
A method of forwarding data in a hierarchial cache memory architecture for a data processing system, said method comprising the steps of:issuing a command from a processor to a first and a second level of cache memories, wherein said first level of cache memories is in a higher hierarchial order than said second level of cache memories; in response to said command being a Demand Load command, immediately forwarding data corresponding to said Demand Load command from said second level of cache memories having said data corresponding to said Demand Load command to said processor; and in response to said command being a Prefetch Load command, forwarding data from said second level of cache memories having said data corresponding to said Prefetch Load command to a cache reload buffer within said first level of cache memories, wherein said first level of cache memories is immediately preceding said processor in said hierarchial cache memory architecture.
