Ying Is Next Gen (Ying)

Ying is a microcontroller based on a 16 bits RISC microprocessor with a 5-stage pipeline.
It was designed to run C code compiled with the yang compiler.

This code is written in VHDL and can be synthesized using GHDL.

Functionalities

Some of Ying's functionalities include support for:

• arithmetic operations
• registers setting / copying / loading / storing operations
• loading RAM from file (totxt tool can be used to transfrom binary to txt format)

Usage

To synthetize a specific component and run its tests:

~/ying $ make TEST=pipeline

To synthetize ying and run its tests:

~/ying $ make TEST=ying

To transform a binary into a "txt-binary" file:

~/ying/data $ python3 totxt.py binary_file

This will output a binary_file.txt readable by the RAM component.

Requirements

GTKWave is used to visualize the digital timing diagrams.
