Overview

Introduction to Hardcaml

Capstone 1: solve Advent of Code problems

Capstone 2: write a blinker and counter program

Capstone 3: implement Binary Search

Capstone 4: implement Conway's Game of Life

Specialized Hardware Projects

The CHIP-8 machine implementation by jawline includes a custom assembler for writing test programs, showcasing how complete systems can be built using Hardcaml. The L4 load balancer project demonstrates network processing capabilities, as discussed in the OCaml forum post about load balancer implementation on FPGA.

The hardcaml_riscv project implements a RISC-V 32IM CPU, while risk5 provides another RISC-V CPU implementation. The hardcaml-mips project offers a MIPS architecture implementation, with detailed documentation available at the Ceramic Hacker blog.

Building a Hardcaml Language Server Protocol (LSP) implementation enhances the development experience by providing IDE support with features like auto-completion, error checking, and refactoring capabilities. Establishing CI/CD pipelines for Hardcaml projects ensures code quality and facilitates team collaboration, following practices similar to those described in the Jane Street Style Guide.

A high-frequency trading (HFT) implementation in Hardcaml could leverage hardware's inherent parallelism for ultra-low latency trading systems. Similarly, building a cryptographic library in Hardcaml would provide hardware-accelerated cryptographic primitives, essential for secure applications.

Implementing comprehensive test suites using frameworks like gtest and Alcotest for OCaml ensures code reliability. The lightweight and colorful Alcotest framework particularly suits Hardcaml projects, providing clear test output and easy integration with existing OCaml toolchains.

Development Environment and Tools

Learning Path Optimization

Following the path of least resistance involves identifying common hurdles in Hardcaml, overcoming them systematically, and documenting prototype iterations. The Ceramic Hacker's OCaml setup guide provides practical insights into project planning and basic setup procedures. Completing Real World OCaml by month's end, with focus on Hardcaml code examples and patterns, establishes a solid foundation in the underlying language.

Initial Setup and Learning Resources

Setting up a Hardcaml development environment begins with understanding the framework through resources like the Hardcaml mini-course at Stevens, which provides project templates and structured learning paths.

Code Quality Practices

Following established coding standards, such as Google's C++ coding style with clang-format scripts for automated checking, maintains code consistency. Github Actions integration enables automated testing whenever changes are pushed to GitHub. Implement code reviews and maintain clean git history.

Creating Accessible Documentation

This documentation should focus on practical examples that demonstrate the translation from familiar software concepts to hardware implementations.

Community Resources

The Hardcaml documentation provides comprehensive API references, while the OCaml package repository offers installation instructions and dependency management. The official Hardcaml module documentation serves as a detailed reference for all available functions and modules.

Understanding Hardcaml's theoretical foundations requires studying resources like the Hardcaml paper and related FPGA research. The blog post series on growing the Hardcaml toolset by Jane Street provides insights into the framework's evolution and future directions.

The Hardcaml ZPrize competition showcases advanced applications and pushes the boundaries of what's possible with the framework. Participating in such competitions provides exposure to cutting-edge techniques and community best practice
