Software Development
- Developed IoT systems for factory automation by using camera sensors.
- Researched and developed deep-learning proof-of-concept system for human detection.
- Developed Web system for managing a large number of network cameras.
- Developed smartphone applications for collecting screen images.
- Researched computer vision feasibility and developed the demo system.
- Developed network camera device, which enables hi-compression video stream output.
Embedded Computer System Development
- Developed 2D/3D graphics computer systems for Arcade Game.
- Verified and debugged Engineering Sample ICs (ES) on computer boards by using Logic Analyzer.
- RTL Design
- Developed low-power, complex math operation RTL modules for ASIC by SystemVerilog.
- Planned 3D graphics IP Core system architecture to satisfy required features, gate size and production schedule.
- Invented the lighting algorism for real-time 3D graphics to generate photo realistic scene image.
- Invented image compression algorithm suitable for real-time image decoding.
- Functional Verification/Hardware Emulator
- Built SystemVerilog verification environment with random data generation, assertion, and functional coverage.
- Improved ASIC verification time by porting the designs from RTL simulation environment to a hardware emulation system environment.
- Evaluated the performance of the hardware emulation system to be introduced when multiple designs shared emulator resources simultaneously.
- Planned ASIC functional evaluation strategy and implemented on RTL simulation environment.
- Planned and built functional verification environment for RTL designs by using black-box, white-box and gray-box testing methods, implemented by hardware verification language (e language).
- Verified standard interfaces (PCI, USB and AMBA AHB) with e verification language.
- Instructed e verification language methodology to HDL designers of customer companies.
- Built the Japanese FAQ web site of e verification language for Japanese HDL designers.
FPGA
- Built processor systems with the designs under test on FPGA based-prototyping systems for robust RTL verification, early software development and IP Core demonstration.
- Improved middleware development time by building FPGA based-prototyping system before actual ASIC production.
