Latest Patents
One of Lapp's latest patents is titled "Hardware accelerator automatic detection of software process migration." This invention provides a mechanism by which a hardware accelerator detects the migration of a software process among processors. It utilizes a mapping table that includes cache memory identifiers associated with processor identifiers. This allows the hardware accelerator to write operation results to the appropriate cache memory, facilitating faster access by the current processor.
Another notable patent is the "Method and apparatus for acceleration of hash-based lookup." This invention features a hash accelerator that receives a hash key value from a processor core. It determines the main memory address of the corresponding hash table entry and stores it in a cache memory accessible by the processor core. By executing the same hash function as the processor core, the hash accelerator can provide the hash table entry from cache memory before the core attempts to access it, thus avoiding cache misses and improving overall efficiency.
