Optimized ImHex's search functionality through precomputed lookup tables and dependency chain splitting, achieving 2x end-to-end improvement and 5x microbenchmark speedup.
Lookup Tables & Chain Splitting
Read Case Study →Delivered a carefully optimized AVX2 kernel that reduces inner‑loop overhead and exploits wide data parallelism, achieving 2.5x speedup without altering boundary handling.
SIMD & AVX2 Acceleration
Read Case Study →Reduced redundant loads, placed compiler branch prediction hints, and changed swaps to be direct, achieving incredible 66.1% increase in rows per second.
Branch Hints & Load Optimization
Read Case Study →From bottleneck to speed in one command
Functio automates the entire optimization workflow — profiling, benchmarking, code generation, recompilation and correctness verification.
Profile
Leverage compiler reports, perf, gdb, and other tools to pinpoint bottlenecks in real time.
Verify
Capture the functionality of the original code on built-in tests and generated tests
Optimize
Find the most optimal implementation for a specific functionality.
Verify
Validate correctness on all inputs and measures cycle-level performance gains.
