Latest Patents

Nakanishi's latest patents include an innovative instruction cache memory apparatus with an advanced read function. This invention provides a low probability of occurrence of cache errors. The instruction cache memory features an advanced read function that allows for the provision and reception of instruction information in block units to and from a main memory. It includes an instruction analysis section that predicts the necessity of reading the next block from the main memory by analyzing the instructions currently being transferred to the instruction cache. Additionally, circuits are in place to read out the next block from the main memory when deemed necessary by the instruction analysis section.

Another notable patent is her branch prediction system for superscalar processors. This system utilizes branch target buffers (BTBs) that store branch prediction information on branch instructions, including a 2-bit offset indicating the location of the branch instruction within a cache block. The BTBs simultaneously output branch prediction information based on an executable instruction address, allowing for more efficient processing.
