Latest Patents

Shintani is credited with 1 patent: “Digital Data Processor with Two Operation Units.” The invention describes a processor that divides instructions into stages and uses two execution units. One unit can perform operations required by all instructions, while the other handles operations required by only some instructions. Separate circuits select queued instruction data for each unit and advance it in step with that unit’s operations. This arrangement helps ensure that an instruction stage dependent on an earlier operation waits for the relevant execution unit to finish, even if the other unit is processing a different instruction.

Career Highlights

Shintani’s listed patent reflects work on instruction pipelines, execution-unit coordination, and the handling of dependencies between instructions. His company affiliation is Hitachi, Ltd.
