ARM Instruction-Based Image Processing Optimization

Soongsil University · Microprocessor Course Project

• Contribution: Participated in comparing and analyzing execution performance across memory layouts and instruction optimizations, and organized performance measurements and output-validation results
• Execution-time improvement: After instruction optimization, execution time decreased by 21.55% for brightness adjustment, 31.89% for binarization, and 27.94% for blur processing compared with the pre-optimization baseline
• Instruction analysis: Confirmed a 75% reduction in input load instructions in the image-processing section and compared changes in total instruction and branch instruction counts
• Output validation: Found zero byte mismatches and mean squared error (MSE) of 0 between the compared outputs for all three image-processing functions, confirming identical output after optimization

Processor and Cache Performance Analysis Using SimpleScalar

Soongsil University · Computer Architecture Course Team Project

Role: mcf benchmark analysis

• Performance analysis: Compared and visualized the mcf benchmark’s IPC and CPI across ALU counts, instruction issue widths, branch predictors, and cache configurations
• Processor configuration comparison: Increasing the instruction issue width (Scalar width) from 1 to 4 yielded a 39.8% increase in IPC
• Cache configuration analysis: Found that the relative performance of LRU and Random replacement policies changed with block size, and analyzed interactions among settings

Ignight Capital

Research Intern · Korea

• Protocol analysis: Reviewed technical documents and major updates for DeFi protocols; documented fund flows, collateral and staking structures, and version-specific changes in research reports
• Revenue and usage conditions: Compared revenue sources, incentives, liquidity, and fees across platforms; recorded transaction costs and processing times for deposits and withdrawals
• Prediction-market strategy research: Studied trading and reward structures and strategies for identifying arbitrage and other opportunities; assessed conditions and limits related to price volatility, liquidity, and data dependence
• Bot development support: Used Claude as a coding aid while contributing to arbitrage and prediction-market opportunity-scanning bots

Mobile Game Development — Planet10 & PlanetPop

Team Project

• Collaborative development: Co-developed two mobile puzzle games based on established game mechanics, contributing to feature planning, UI/UX design, and implementation
• Feature extensions: Contributed to ticket rewards and collectible planet cards in Planet10, and four game modes, gameplay items, and planet customization in PlanetPop
• Release outcomes: Team releases included Planet10 on Google Play and PlanetPop on the App Store; PlanetPop also incorporated Game Center, Firebase Analytics, and AdMob integration
