In this page the ISOLDE public deliverable reports are published and available for download. They are structured in-line with the overall ISOLDE structure.
The requirements and specifications will be established early in the project in WP1 and will drive the 3 development WPs. The focus of WP2 is the development of foundational cores including core specific infrastructure IPs as used in the memory hierarchy, such as high-performance caches, NoCs and multi-core support. The focus of WP3 is domain specific accelerators for applications such as cryptography, machine learning and vector units for high-performance. All the work on application SW, tools, compilers and automation will take place in WP4. To ensure that the components will work together and can be used to build systems, multiple demonstrators in 4 domains will be built, and these are the focus of WP5. There are many administrative and legal challenges that are specific to developing complex SoCs that integrate open-source blocks that can have different licensing terms. It is important that these be fully addressed, and these constitute a key aspect of WP6, which also includes the exploitation and dissemination activities. Finally, WP7 covers the project management, including the coordination between partners and reporting to the commission.

The purpose of this document is to collect the initial requirements for the demonstrators in the chosen application areas (Automotive, Space, Smart home, IoT), as worked out in T1.1.
It contains both functional and non-functional requirements, at least from the following subjects: architecture (components, interfaces, accelerators), measurable metrics and goals (performances, power consumption, radiation tolerance, security metrics to be used), SW requirements (stacks, tools, system SW features, SW for demonstrators use cases), and standard to be used/considered.
The main goal of this document is to have a sound starting basis for further iteration and refinement in the different WPs of the project. Some of the requirements have already been worked out in full detail, while others still contain some open questions or issues to be finalized. For example, regarding verification and validation, further refinement and updates are still needed. Such activity will be carried out in D1.3 where the final requirements will be frozen.
This document supports the technical report associated to the deliverable D1.1 “Demonstrators Requirements and Specifications” reporting to the WP1 “Requirements and Specifications” leader (E4 Computer Engineering S.p.A.) for the Project ISOLDE.
The document is prepared in the frame of the Task 1.1 – Collection of requirements of the demonstrators & high-level SoCs specifications (WP1).

The purpose of this document is to collect the requirements for the project demonstrators in the chosen application areas (Automotive, Space, Smart home, IoT), as worked on in T1.1 “Collection of requirements of the demonstrators & high-level SoCs specifications” (M1-M12). The base for this document is the information contained in D1.1 “Demonstrators requirements and specifications”, and D1.2 “Requirements and specifications on architecture, hardware and software modules and IPs”, which has been updated following the progress of the work done in WP2, WP3, WP4 and WP5 adding also more detail on IPs implementation as well as the definitions of the architectures of the planned demonstrators. D1.3 is the final outcome of T1.1.
The document contains both functional and non-functional requirements for the following subjects: architecture (components, interfaces, accelerators), measurable metrics and goals (performances, power consumption, radiation tolerance, security metrics to be used), SW (stacks, tools, system SW features, SW for demonstrators use cases). There are also references, where significant, to standard to be used/considered.
D1.3 includes an overview of each demonstrator, whose objectives and proposed architecture are described in more detail in D5.1 “Description of demonstrators architecture” (due M12, same as this document), to contextualize the requirements and the verification strategy attached to them.
This document supports the technical report associated to the deliverable D1.1 “Demonstrators Requirements and Specifications” reporting to the WP1 “Requirements and Specifications” leader (E4 Computer Engineering S.p.A.) for the Project ISOLDE.

The ISOLDE project aims to create high-performance processing systems and platforms targeting different use cases (space, automotive, smart home, cellular IoT) based on the free, open-source RISC-V instruction set architecture. This document defines the initial architecture of the required hardware modules and extensions (called extensions in the following) developed within the work package WP3 “Accelerators and Extensions” of the ISOLDE project to reach this goal. It encompasses contributions from all tasks (T3.1 to T3.6) and partners within WP3.
The extensions described in this report are grouped into different domains matching the scope of the different tasks within WP3:
For each extension, this document contains general information (type, dependencies, and license) and an initial architecture description giving a first insight into its purpose and internals. These initial architecture descriptions answer core questions about each extension:
WP5 “Use Cases and Demonstrators” will combine the foundational cores developed by WP2 “Open-source Foundation Cores” and selected features from WP3, building diverse demonstrators (space, automotive, smart home, cellular IoT) that highlight benefits and opportunities enabled by individual extensions. Further, WP4 “System Software, Development Tools and Automation” will provide the required software support (e.g., toolchains, operating system support, drivers). Hence, the contributions of this deliverable are crucial for further collaboration with these work packages. In the context of WP3, this deliverable is the basis for the follow-up deliverables covering the prototype and final implementations of the extensions (D3.2, D3.3 in M24 and D3.4, D3.5 in M33). The components described in this deliverable are aiming at different maturity levels and aiming for different certifiability. Further, this document represents the first iteration of the architecture definitions and hence not all contributions have the same level of maturity. A short survey of the ISOLDE partners for certification intentions (including WP3 components) will be later provided by SYSGO as part of WP1 work.
13 May 2024
This Deliverable reports the proposed architectures of the four Demonstrators (Space, Automotive, Smart Home, Cellular IoT) in four separate sections, as well as providing a more detailed description of the use case applications. A consolidated version of the Demonstrator requirements is instead provided in Deliverable D1.3, written at the same time. All partners involved in WP5 contributed to this Deliverable.

This document is prepared in the frame of the Tasks 6.2 “Outreach and Dissemination’’ and Task 6.3 “Exploitation’’ – (WP6).
Since ISOLDE is an open-source project, dissemination is essential for many reasons. Firstly, for maximizing impact: open-source projects thrive on collaboration and community engagement. Dissemination allows project outcomes and innovations to reach a wider audience, increasing the potential for adoption and utilization. By sharing knowledge, code, and documentation, open-source projects can have a broader impact and contribute to solving real-world problems. ISOLDE is aimed to build and contribute to the Reduced Instruction Set Computing (RISC)-V ecosystem in Europe, and although we have many stakeholders available in the project, outreach to external stakeholders is essential to reach maximum impact. This will also be done in close cooperation with the TRISTAN project which has similar ambitions. ISOLDE differentiates from TRISTAN by focusing on “stronger” application processors as to the “"smaller” processors targeted by TRISTAN.
A well-designed dissemination approach will facilitate new collaborations. By making ISOLDE results publicly available, it becomes easier for others to contribute, provide feedback, and build upon the work done. This collaborative approach fosters innovation and accelerates the development of new ideas and solutions. Extension of the ISOLDE network to other stakeholders in open-source will help to increase the community and that will foster acceleration of innovations within ISOLDE.
Finally, we strongly believe that by getting feedbacks during dissemination activities from the RISC-V community, the quality and reliability of the IP blocks developed in ISOLDE will be improved. Although ISOLDE targets to achieve a Technology Readiness Level (TRL) 6, a large stakeholder community can help identify bugs, improve functionality, and enhance the overall quality and reliability of the project. This deliverable describes through the proposed dissemination plan the methodology and tools to be used to generate maximum dissemination impact.
Beyond dissemination, exploitation is also of crucial importance. Exploitation is a must-have to ensure that results end up in the market in a successful way. ISOLDE primarily aims to enhance and mature the European RISC-V ecosystem and to support the ongoing shift towards open source methodologies and solutions in that context. Therefore, one of the results will be exploited via open-source and others via different licensing mechanisms. Some of the results will remain company-confidential and will be exploited by individual partners on the market. This first version of the exploitation plan has been drafted at the end of year 1 of ISOLDE. During this stage initial technical results have been achieved, but technical maturity still needs to increase. The information in Section 3 of this document supplements exploitation information in Part A and Part B of the Grant Agreement and includes contributions from partners with addenda thereto.
