A simple example of a mandelbrot fractal for RISCV RV32I CPUs in assembly language.

mandelbrot.asm is a bare metal assembly example for the Longan Nano.
It computes a standard mandelbrot fractal in fixpoint math on the 160x80 LCD.
size 918 Bytes (1234 Bytes without C extension).

The code assembles well with the wonderful bronzebeard.
Another bare metal example is here: lz4 decoder.
