With an impressive portfolio of 9 patents, Rafacz has demonstrated a remarkable ability to innovate and improve systems, particularly in memory operations and instruction execution.

Latest Patents

Among Rafacz's latest patents is the "Lock Address Contention Predictor," which introduces techniques for selectively executing a lock instruction either speculatively or non-speculatively, depending on lock address and temporal lock predictions. This invention provides methods and devices for effectively locking an entry in a memory device. It detects whether contention occurred for a particular memory entry during an earlier speculative lock, determining the execution of the lock instruction based on this detection.

Another notable patent is "Store-to-Load Forwarding," wherein an arithmetic unit performs forwarding based on predicted dependencies between store and load instructions. This invention maintains a table of store instructions awaiting movement to a load/store unit within the instruction pipeline. When a load instruction, predicted to depend on a specific store instruction, is received, the arithmetic unit efficiently maps the physical registers to ensure seamless data flow.
