[ujson] Json implementation for firmware The `ujson` library represents a command/control/status interface between Rust-based test harnesses and riscv32-based test programs. The library allows one to define structs and enums in a C-preprocessor domain-specific-language and automatically generate: - The C language structs and enums. - The C language serializer and deserializer for those structs/enums. - The Rust language struct/enum definitions with appropriate `serde` attributes to enable serialization and deserialization. The files `example.[ch]` provide a basic guide showing how to declare structs and enums. The files `example_roundtrip.c` and `rust/roundtrip_test.rs` demonstrate data exchange between C and Rust programs. The preprocessor techniques used to generate the parser and emitter code are somewhat advanced, but well known techniques. See the page [C Preprocessor tricks, tips, and idioms](https://github.com/pfultz2/Cloak/wiki/C-Preprocessor-tricks,-tips,-and-idioms). Because these techniques rely on the comma elision with variadic macros, we must use the `gnu` compiler extensions (`-std=gnu11` and `-std=gnu++14`). Signed-off-by: Chris Frantz <cfrantz@google.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.
