Latest Patents

Zelin Zhang's latest patents include innovative techniques related to graphics processor data caches. One of his patents, titled "Scoreboard for Register Data Cache," discloses methods for executing instructions that operate on input operands from architectural registers. This invention features data cache circuitry that caches architectural register data for the datapath circuitry. The scoreboard circuitry tracks map information indicating whether an architectural register is mapped to an entry of the data cache circuitry, along with a pointer to that entry. Additionally, tiered scoreboard circuitry and data storage circuitry may be implemented to enhance cache performance, reduce power consumption, and minimize area.

Another significant patent is "Cache Control to Preserve Register Data," which focuses on eviction control for cache lines storing register data. This invention involves memory hierarchy circuitry designed to provide memory backing for register operand data in various cache circuits. The lock circuitry controls a set of lock indicators for registers utilized by decoded instructions of a specific thread, preserving register operand data in the cache circuits and preventing eviction based on asserted lock indicators. These techniques aim to retain relevant register information in the cache while minimizing control circuit area.
