Latest Patents
Cissy holds a patent for a system and method titled "Speculative Memory Prefetch." This invention focuses on pre-fetching data from system memory to improve efficiency. The technology involves a multi-core processor that accesses a cache hit predictor while simultaneously sending a memory request to a cache subsystem. The predictor utilizes two tables: the first table is indexed by a portion of a memory address and provides a hit prediction based on a first counter value, while the second table is indexed by a core number and offers a hit prediction based on a second counter value. If neither table predicts a hit, a pre-fetch request is sent to memory. In cases where the hit prediction is found to be incorrect, the pre-fetch is cancelled, ensuring optimal performance.
