Cache preload operations using streaming engine

A method comprising:

• receiving an instruction that specifies a base address, a data size, and a level of a cache memory to operate on;
• determining, based on the base address and the data size, a set of addresses associated with the instruction;
• and
• issuing a set of cache preload operations to the cache memory that includes a cache preload operation for each address in the set of addresses, wherein:
• the instruction has an associated privilege level;
• and
• the method further comprises:
• for each cache preload operation in the set of cache preload operations, determining whether the privilege level permits preload of the respective address of the cache preload operation;
• and
• when the privilege level does not permit preload of a first cache preload operation of the set of cache preload operations, dropping the first cache preload operation while proceeding with a remainder of the set of cache preload operations.

A method comprising:

• receiving an instruction that specifies a base address, a data size, and a level of a cache memory to operate on;
• determining, based on the base address and the data size, a set of addresses associated with the instruction;
• issuing a set of cache preload operations to the cache memory that includes a cache preload operation for each address in the set of addresses;
• determining whether each cache preload operation of the set of cache preload operations is directed to cacheable memory;
• and
• when a first cache preload operation of the set of cache preload operations is directed to non-cacheable memory, dropping the first cache preload operation while proceeding with a remainder of the set of cache preload operations.

A system comprising:

• a processor;
• a memory coupled to the processor that includes a cache memory;
• and
• a memory component coupled to the processor and the memory, wherein the memory component is operable to:
• receive an instruction from the processor that specifies:
• a set of data;
• a level of the cache memory to preload with the set of data;
• and
• whether to preload the level of the cache memory with the set of data for a subsequent read or a subsequent write to a set of addresses of the set of data, wherein the subsequent read or the subsequent write occurs after the cache memory has been preloaded with the set of data;
• determine the set of addresses based on the instruction;
• and
• issue a set of cache preload operations to the cache memory that includes a cache preload operation for each address in the set of addresses.
