2. Paper Topic: “Thumb-Drive-Sized CPU: A RISC-V Implementation Using Only Concepts from 'Computer Fundamentals'”

Why it’s interesting: Shows that a toy 8-bit CPU (like the SAP-1) can be built on an FPGA using just the basic building blocks Rajaraman describes: registers, ALU, control unit (finite state machine), and memory addressing.
Connection: Chapters 9–11 (CPU, Control Unit, Memory).
