RISC-V Assembly Simulator is a mobile 32-bit system simulator. The app simulates the entire system, all the way from each individual unit on a CPU to the memory subsystem. Write assembly natively to the CPU, with a built-in debugger so you can analyze your code and see what the hardware is doing. This app is designed to allow you to learn how to write assembly from your mobile device, simulating a real CPU at your devices maximum speed. Visualize how the hardware works if you want to, see all the registers, see your entire memory subsystem for each cycle. Learn the components of this individual CPU. This app currently supports the base Int for RV32 along with the M extension, allowing multiplication and division. Dual core systems are supported with the atomic instructions. This app features a built in assembler to allow you to learn to write code along with descriptive errors. Code along with Apple Intelligence, giving you advice and helping you fix bugs along the way (experimental). Natively integrated with your devices file system, allowing seamless transfer between devices and potentially other sources.
