[otbn] add optimized 384 bit Barrett mult for P-384 Adds a variant for the 384 bit Barrett redcution based modular multiplication algorithm optimized for and limited to the NIST P-384 curve. Differences to generic version: - The multiplication sequences are inline to reduce move instructions and enbale different configurations for the multiplications - Use optimized multiplication sequences exploiting the special form of the P-384 modulus - Only a single conditional subtract of the modulus at the end Signed-off-by: Felix Miller <felix.miller@gi-de.com>
OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
