Vrishchik RISC-V emulator

An open-source RISC-V emulator written in java, using the swing framework.

Features:

General:

• independent compiler and processor with generation of standard binary files
• all 32 basic commands of RISC
• additional pseudo commands

Compiler:

• transcript of step-by-step compilation
• binary file preview
• decompiled code preview
• points out line number and nature of error

Processer:

• step execution
• breakpoints
• execution in independent threads to prevent crashes

GUI:

• inbuilt console
• support for 2,8,10,16 bases, signed and unsigned, ASCII
