Introduction

Yuko Imanishi is a prominent inventor based in Higashihiroshima, Japan. She has made significant contributions to the field of computer science, particularly in program execution control and garbage collection systems. With a total of 2 patents, her work has had a notable impact on the efficiency of software execution.

Latest Patents

Imanishi's latest patents include a program execution control device and a garbage collection system. The program execution control device addresses the challenges faced by home appliances equipped with processors that implement a conventional Java Virtual Machine (JVM) with a Just-In-Time (JIT) compiler. It enhances execution speed by determining whether a method has been previously compiled. If a method is uncompiled, the device interprets the associated bytecodes while issuing a compilation request. Conversely, if the method is compiled, it executes the native code generated from the compilation. This innovative approach allows for more efficient program execution.

The garbage collection system developed by Imanishi reduces the CPU time required for garbage collection without excessively halting all application program threads. This system effectively frees memory areas corresponding to objects that are no longer needed in an object-oriented program with multiple threads. It includes a selection unit to choose threads, an examination unit to manage accessible objects, and a freeing unit to release memory areas for non-freeing targets. This advancement significantly optimizes memory management in complex software environments.
