[otbn] default increment dmem pointer for dmem access operations with two pointer increments (reg pointer and dmem) pointer only one increment can be handled in the load/store instruction. The other increment is handeled in a subsequent `addi`. This adjusts the increments such that always the dmem pointer is incremented in the load/store and the reg pointer in the `addi`. This has the advantage that an immediate of `1` can be used for the `addi` instruction regardless of the type of addressing used for dmem. 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.
