Development of High-level System Design and Verification

High-level Design and Verification for Embedded Systems
Model checking plays an important role in the design oflarge scale and complex systems. The technique is applied
to software requirement specifications and design
specifications, and aims to increase the reliability andproductivity. The objective of the work described is toprovide a tool chain that supports using SPIN to modelcheck systems specified as Simulink Stateflow models.
Hardware design of algorithms
Bilateral filter can be implemented at a one-chip circuit
scale on a Xilinx FPGA.
Parallel processing using GPU
Estimation method of parameters has been proposed as the standard deviation of the prior probability
noise distribution. Super Resolution method has been proposed that combines Bilateral Back Projection
using Local Variance (BBPLV) and the detection of similar structure and data fusion.
High-level design verification of digital systems using model checking
Tool chains are considered that support using SPIN to model check systems specified as Simulink
Stateflow models.
Advantages for previous techniquesVerification shows especially efficient results for structures included behaviors and data using ourproposed method.

Development of e-AT（Electronic and Information Technology Based AssistiveTechnology） tools

・Development of the Joystick-Type Controller for Physically Disabled ChildIn the nearby special school, In order to practice the operation of motorized wheelchair, physically disabledchild have towed a wheelchair by radio-controlled car. In this study, child operates radio-controlled car by himself
and it is aimed to lead to practice the operation of joystick-type controller. Because come out individual
differences into joystick operation by individuality of disabilities, physically disabled child is required support
and adjustment of the equipment that corresponding to disability. In this paper, we developed the joystick-type
controller that can be regulate the reaction angle of the joystick automatically for support to physically disabledchild's joystick operation.

Coding and decoding technologies with optical signal processing

I conduct a study on functional components of optical signal processing to realize more sophisticated opticalcommunication system in the next generation. The research topics in my study are summarized as follows.

Optical Comparison Operation
I propose an optical comparison operation, which is a key module of an optical switch or router to replaceelectrical calculation with optical calculation. I experimentally demonstrated optical comparison operation for 4-bit
QPSK-modulated signal, and evaluated their BER performance. The result indicates that the correct comparison
operation for QPSK signal can be achieved without electrical processing.
Optical Digital-to-Analog Conversion
I propose an optical digital-to-analog (DA) conversion to realize an optical switch or router. I experimentallydemonstrated optical DA conversion for 2-bit BPSK-modulated signal. The result indicates that the correct
operation for BPSK signal can be achieved without electrical processing.
Optical Integration Circuit with Silicon Photonic Technology
I propose two types of optical integrated circuit by using silicon photonic platform. I designed the circuits;
namely, optical FEC coding circuit and optical comparator, respectively. I experimentally evaluated their basicperformances.
