C++ Macro definitions for easy branch hinting.

Processor RISC-V and application

Design and development of a complete RISC CPU with: five stage pipeline, forwarding, automatic hazard detection, BTB using LRU policy replacement, four-cycle hardware multiplier.

Spectre attack variant 1 is used here to extract an image data buffer from a program. The output image data is then decoded and median filters are applied to remove the hot pixels in the output image. Here I have included files for RGB and base64 format.
