Latest Patents

One of her latest patents is titled "Evicting appropriate cache line using a replacement policy utilizing Belady's optimal algorithm." This invention presents a method, system, and computer program product for cache replacement. The innovation leverages Belady's optimal replacement algorithm by applying it to past cache accesses to inform future cache replacement decisions. The occupied cache capacity of a cache is tracked at every time interval using an occupancy vector. The cache capacity is retroactively assigned to the cache lines of the cache in order of their reuse. A cache line is considered a cache hit if the cache capacity is available at all times between two subsequent accesses. The occupancy vector is updated using a last touch timestamp of a current memory address. A determination is made as to whether the current memory address results in a cache hit or a cache miss based on the updated occupancy vector. The replacement state for the cache line is stored using the results of the determination.

Another significant patent is "Power management of instruction processors in a system-on-a-chip." This invention involves a system-on-a-chip that includes a plurality of instruction processors and a hardware block, such as a system management unit. The hardware block accesses values of performance counters associated with the plurality of instruction processors and modifies one or more operating points of these processors based on comparisons of the instruction arrival rates and the instruction service rates. This optimization aims to achieve improved system metrics.
