The ZKTC project is a hobby project that involves designing a CPU, creating a compiler for it, and running various programs on the CPU.
The ZKTC (CPU) is a 16-bit CPU implemented in SystemVerilog and can run on an FPGA. It supports UART, GPIO, and interrupts. Programs written in ZKTC-C (a language similar to C) can be compiled using the ZKTC-C-com (compiler) and executed on the ZKTC.
The program/app/sample folder contains several applications that can be executed using the Z-kernel (program/kernel).
Turn on the LED using GPIO
Hangman Game
Mandelbrot Set Plot
The files required to build the FPGA image are the files under src/ and boot1.mem, boot2.mem.boot1.mem and boot2.mem can be created in the program/ folder using the make command.To create them, you need zktc-c-com (compiler) and zktc-asm (assembler).
Currently, it has only been tested on the Arty S7, but it should work on other FPGA boards as well.
Using the make command in the program/ folder will generate .bin files in each folder under program/app/sample.
When you start ZKTC, you can enter commands via UART. When you enter the load command, it will wait for a transfer, so please transfer the application binary using XMODEM via UART. Once Loaded successfully. is displayed, you can start the application with the run command.

Loaded successfully.
> run
Tests can be run by using the make command in each folder under test/. Icarus Verilog is required to run the tests.
