Summary
This episode continues the 'Negative Cost Embedded C++' series, focusing on further optimizing embedded code by consolidating multiple register operations. Jason demonstrates how combining several register bit settings into a single operation using a simple register wrapper with C++17 fold expressions can reduce compiled instruction count. By eliminating redundant volatile memory operations, the code becomes not only more concise but also more efficient, illustrating how modern C++ features can improve embedded programming beyond what traditional C offers.
