09/2007- 06/2009

Overall GPA 3.73/4.00

BACHELOR OF ENGINEERING

Department of Communication Engineering

National Chiao Tung University (NCTU), Taiwan

09/2000-06/2004

Last 2 years 3.89/4.00

COURSE Energy efficient embedded system design: Implemented a Dynamic

PROJECTS Voltage/Frequency Scaling (DVFS) policy on XScale, and ran mplayer

with various audio/video files to compare the energy saved by the

policy

Developed with XScale PXA27x processor on Intel's platform Mainstone

Wrote a utility that periodically calculates CPU utilization and

switch operation mode

Modified a Loadable Kernel Module (LKM) and used Power Management

Unit (PMU) of Xscale to implement a DVFS policy

Wavelet application - object detection: Used Haar wavelet to

implement a fast object detection for face and speed limit sign

Developed with OpenCV library

Ambiguity Function: Distorted received signals, and observed their

resistance to different types of distortion, the frequency and the

arrival time, by recording the output of matched filters

Simulated in MATLAB

Plotted those ambiguity surfaces
