Latest Patents

Hongzhou Zhao holds a patent for a method and directory system known as Sharing pattern-based directory coherence for multicore scalability, abbreviated as 'SPACE'. This invention provides a mechanism that recognizes and represents the subset of sharing patterns present in an application. The term sharing pattern refers to a group of processors accessing a single memory location in an application. The sharing pattern is decoupled from each cache line and held in a separate directory table. The sharing pattern of a cache block is represented by a bit vector that indicates which processors share the block. Multiple cache lines with the same sharing pattern point to a common entry in the directory table. Furthermore, when the table capacity is exceeded, similar patterns are dynamically collated into a single entry, enhancing the system's efficiency.
