Latest Patents

One of Imori's latest patents is a processing device with prefetch instructions that include indicator bits specifying cache levels for prefetching. This invention describes an information processing system that consists of a main memory and a processing unit. The processing unit executes a prefetch instruction, which is part of a program stored in the main memory. The system features an internal cache functioning as a first-level cache and an external cache controlled as a second-level cache. The prefetch instruction enables the processing unit to selectively perform a prefetch operation, transferring operand data from the main memory to the caches before executing subsequent load instructions. The instruction includes multiple indication bits that specify the cache levels for data transfer.

Another significant patent by Imori also involves a processing device with prefetch instructions. This system includes a processing unit that executes prefetch instructions from a program in the main memory. It features two hierarchical level caches connected to the processing unit and the main memory. The primary cache, which is closer to the processing unit, serves as the first-level cache, while the secondary cache, closer to the main memory, acts as the second-level cache. The prefetch instruction allows the processing unit to perform a prefetch operation by transferring operand data to the two hierarchical level caches before executing the subsequent load instruction.
