Version 0.2 expands on the original manual ALU functionality by adding a CPU mode that automatically executes pre-programmed instructions. To enable this, key CPU components such as a Program Counter (PC), an instruction decoder, and a register file have been integrated.

This first version was created entirely during mandatory military service in South Korea, demonstrating that hardware innovation is possible even in the most limited environments. Future versions will expand JSilicon into a more capable CPU core RISC-like capabilities.

버전 0.2는 원래의 수동 ALU 기능에 CPU 모드를 추가한 구현체입니다. 이 변경으로 미리 ROM에 프로그래밍된 명령어를 자동으로 실행할 수 있습니다. 이를 구현하기 위해서 **프로그램 카운터(PC)**, **명령어 디코더**, **레지스터 파일**과 같은 핵심 CPU 구성 요소들이 추가되었습니다.
