High-bandwidth prefetcher for high-bandwidth memory

A method for prefetching data into a cache, the method comprising:

• during execution of a prefetch instruction that specifies a start address,
• issuing a prefetch request to retrieve a block at an initial prefetch address that is derived from the start address;
• and
• for one or more next blocks, issuing a prefetch request to retrieve the next block, the block at a next prefetch address that is derived from a prior prefetch address associated with prior retrieval of a block.

Computer logic for prefetching data, the computer logic comprising:

• issue prefetch request logic that during execution of a prefetch instruction that specifies a start address,
• issues a prefetch request to retrieve a block at an initial prefetch address that is derived from the start address;
• and
• for one or more blocks, issues a prefetch request to retrieve a next block at a next prefetch address that is derived from a prior prefetch address associated with retrieval of a prior block.
