FiveDex — RISC-V Adoption Index

What it measures

FiveDex tracks real-world adoption of RISC-V by measuring what matters most: whether parts are available and moving through the supply chain. Every day it queries the official APIs of the world's largest semiconductor distributors and aggregates live inventory for hundreds of RISC-V components.

The result is a single number that rises when RISC-V parts become more available across more distributors, and falls when supply contracts. No surveys, no estimates, no self-reported data — only real inventory from real distributors.

Methodology

Patent pending · USPTO provisional 64/147,920

1Discovery — search distributor APIs for RISC-V parts

2Classification — confirm RISC-V architecture per part

3Crawl — fetch live stock quantity from each source

4Score — log1p on stock depth, mean per source

5Weight — weighted sum across sources

6Smooth — EWMA α=0.30 for day-over-day stability

7Normalize — base 100 from initial measurement
