RISC-V Single Cycle Core

RISC-V RV 32I is an open-source instruction set architecture that follows the principles of reduced instruction set computing (RISC). It's designed to be simple, modular, and extensible. This architecture is based on 32-bits implementation for base integer instruction set (extension I). A single-cycle core refers to a processor design where each instruction takes just one clock cycle to execute.

This core is specifically designed to perform load-word I-type instruction.

• I-Type instruction implemented : opcode | rs | rd | Immediate (load)
