Kasahara Lab
Machine-translated · View original
A lab that uses parallelizing compilers to make multicore processors run fast and with low power consumption.

AboutAbout the lab
Research on compilers that parallelize programs automatically
The Kasahara Lab studies parallelizing compilers and multicore processors.
The lab develops an automatic parallelizing compiler called the "OSCAR compiler" and works on technology that automatically distributes a program across multiple cores so that it runs fast.
The lab also conducts research on low power consumption and green computing, including compiler technology that automatically reduces power consumption.
The lab also has applications in familiar devices in view, such as medical image processing and driver-assistance systems.
Key terms
- Parallelizing compiler
- Software that automatically rewrites a program so that it can run simultaneously on multiple processing units (cores)
- Multicore
- A processor that has multiple processing units (cores) within a single chip
- Green computing
- The idea and the technologies aimed at reducing the power consumption of computers as much as possible
ResearchResearch themes
The Kasahara Lab studies parallelizing compilers, which automatically distribute a program across multiple cores for execution, and the multicore processors that take advantage of them. The lab aims to achieve both higher speed and lower power consumption through compiler technology.
*Illustrative imageParallelizing Compiler (OSCAR)
The lab develops an automatic parallelizing compiler called the "OSCAR compiler." This technology automatically distributes a single program across multiple cores so that it can run fast.
*Illustrative imageMulticore and Manycore Processors
The lab studies multicore and manycore processors with large numbers of cores, as well as accelerators for embedded devices. It has also produced chips through joint development with Hitachi and Renesas.
*Illustrative imageLow Power Consumption and Green Computing
The lab uses OSCAR compiler technology to study how to automatically reduce the power consumption of multicore processors.
*Illustrative imageApplications in Medicine, Autonomous Driving, and More
The lab also lists applications of multicore and compiler technology to familiar devices among its research keywords, such as medical image processing, capsule endoscopy, and advanced driver-assistance systems (ADAS).
MembersFaculty
The members of the Kasahara Lab consist of faculty, Visiting Associate Professors and Visiting Lecturers at the research institute, visiting researchers, department assistants, and doctoral, master's, and undergraduate students.
