RISC-V International
...
This page serves as the starting point for understanding the status of specifications currently being developed by RISC-V. This status is best represented as progress toward the key Specification Milestones (Plan, Freeze, and Ratification-ready) which are obtained sequentially. Specific status for the relevant status columns is detailed in the Status Key section below. The chairs and vice-chairs of Task Groups, specification authors, and Horizontal and ISA Committee chairs and vice-chairs jointly own ensuring their specifications are listed below and reflect accurate status.
In-process specifications are grouped below into two tables based on whether they impact the RISC-V ISA (In-process ISA Specifications) or not (In-process Non-ISA Specifications). Items should have links to their respective specification repo (), Ratification Plan() if not a Fast-track item, and an Acceptance Criteria Status checklist ().
Completed specifications are tracked in the subsequent sections.
Status of active votes by TSC and Committee Chairs can be found on the RISC-V Vote Status wiki page.
This dashboard does NOT intend to show detailed status (that's available in the status checklist for the specification, ), but rather the general status in the journey to ratification.
NOTE: This page is managed by the RISC-V staff with assistance from each specification owner. To get updates to this page or for questions, contact help@riscv.org.
