VPTERNLOG: The Surprising Efficiency of Ternary Operators
2025-01-22
Paul Khuong's blog post explores VPTERNLOG, a novel instruction using ternary operators for bitvector reduction. Compared to binary operators, ternary operators reduce two values at a time, doubling efficiency. This means half the operations are needed when processing bitvectors, without sacrificing throughput or latency. The author praises VPTERNLOG as a cute, lightweight, and highly efficient instruction.
