1. mini-c-compiler-llvm mini-c-compiler-llvm Public

   A compiler for a subset of C with a hand-written lexer, recursive-descent parser, semantic analyzer, dataflow-based static analyzer, and LLVM IR backend that produces native binaries.

   C++ 1

2. tcp-ip-stack tcp-ip-stack Public

   A TCP/IP stack built from scratch in user space over a Linux TUN device, with a full eleven-state TCP implementation interoperable with real ping, curl, and netcat.

   C++ 1

3. linux-pcie-device-driver linux-pcie-device-driver Public

   Linux kernel module for QEMU's edu PCI device: BAR MMIO, MSI interrupts, DMA, and a blocking ioctl interface — fully testable without hardware via Docker + QEMU.

   C 2

4. memory-allocator memory-allocator Public

   A from-scratch C++17 memory allocator combining per-size-class slab pools with a boundary-tag free list (immediate coalescing), exposed as both a library and an LD_PRELOAD malloc replacement.

   C++ 1

5. cuda-matmul-optimizer cuda-matmul-optimizer Public

   Step-by-step CUDA matmul optimization (naive → tiled → vectorized → coarsened, benchmarked vs. cuBLAS) plus a safe, zero-overhead Rust wrapper around the kernels.

   Cuda 1

6. verilog-mini-cpu verilog-mini-cpu Public

   An 8-bit pipelined CPU in Verilog with a 16-opcode ISA, a 2-stage IF/EX-WB pipeline with branch-flush handling, a Python assembler toolchain, and self-checking testbenches covering ALU, register fi…
