Key features of GOSPL Tool Suite are:

Complete toolset (from RTL to configuration bits) Modular framework for extendibility and adoptability State of the art algorithms implemented 700k lines of fully functional C++ code GUI Based

GOSPL architecture is symmetrical in nature and is madeup by replication of basic tiles. A tile contains logic block and associated routing (switch box, connection box and IN mux) as shown in figure on left. Architecture can support heterogeneous tiles such as memory and multiplier blocks with associated routing, forming memory and multiplier tiles, to meet ASIC performance. Logical silicon realization and details of architectural features are opened up to community along with software toolset. It provides a platform to innovate, improve and define next generation of FPGA architecture and to design an optimized silicon using the state-of-art circuit designing techniques.

Key features of GOSPL architecture are

Software and silicon Friendly Application Friendly

• Optimized for data-path as well as random logic

• Application specific tiles (Hard IP like

memory) can be added. Reliability: No possible faulty wake-up state. Modular and Scalable:

• Different Sizes (up-to 5M gate density)

• Different Shapes (Square & rectangular)

Software & hardware are two integral part of a FPGA. Any aspect of FPGA depends on software and silicon both. For the first time, freedom & opportunity is provided for innovators to experiment/ enhance both Software & Hardware together, which can lead to much higher degree of optimizations.

Co-creation of value

With different member entities working together for the enhancement of community platform, and all sharing the equity in terms of efforts and resources, the end result of such an effort is not just proportional to their efforts but is an aggregate of total value generated by all resources. GOSPL intends to utilize this synergy of many applied minds, resulting in greater innovation.

Meritocracy

GOSPL will be a meritocracy driven initiative. In other words, developers will be encouraged to compete with one another to write the best solution to a given problem. The cleanest and most elegant code will be incorporated in the production package release. To be seen to be “the best of the best” is a strong motivation for serious programmers.

Peer review

It is vital that the GOSPL Platform develops as a rugged and robust environment. To this end developers will be encouraged to undertake critical quality and reliability reviews of code developed by other members in a peer group arrangement. This is consistent with the evolution of other high quality open source programs.

GOSPL COMMUNITY

The GOSPL Community has been created as a collaborative environment where members may freely share information and their own intellectual output for the development of the GOSPL Toolset Project as a whole. The Community will operate as an independent body to support and protect the interests of its members.

The process of downloading source code, modifying it and experimenting with it will be undertaken under the umbrella of the GOSPL License.

The GOSPL Community will comprise of universities, organizations (EDA, IP and Design Houses) and individuals. The interim stage is designed to stimulate the power of the collective intelligence of GIP (GOSPL Industrial Partners), GUP (GOSPL University Partners), GCP (GOSPL Consulting Partners), together hereafter referred to as GC (GOSPL Community) with a restricted license. This would be followed by the collective intelligence of the world through a full open source license.

The open source community is expected to evolve in the following way: GC gets access to the complete source code. All the licensees are free to use, test, experiment and modify the code. Any modifications must however be posted by the licensee back to the GOSPL portal. All members of this community will have full visibility to all the activities on the GOSPL portal.

In the spirit of enhancing the expertise applied to the GOSPL platform development, members are encouraged to introduce new contributors to the GOSPL Community. This way the community expands further

1. At an appropriate stage, the GOSPL code will be declared as full open source and the code will become available to anybody on signature of an online License Agreement. GOSPL members will have the right to redistribute the code and expand the Community further.

2. The community will periodically release newer versions of the software for end user as stable version. Development versions will be released frequently for developer community to develop it further.

3. Eventually a possibility of community releasing various versions of the software compatible with varied FPGA architectures available in the market is envisaged.

PROPOSITION TO MEMBER ORGANIZATIONS

Organizations can build their revenue models around the GOSPL software.

Programmable SOC developers can develop programmable products by embedding available FPGA device architecture into its own system with the corresponding software platform available through community.

1. Any software company can assume the role of GOSPL software packagers, wherein companies can take the GOSPL community software to make peripheral enhancements and base their revenue model on the support and services.

2. Software companies can work with silicon companies or any third party to customize the open

source tool for them. As a further step, Software companies can develop specialized tool for the programmable SOC developers to suit their specific requirements.

IP companies can work towards standardization of interfaces to minimize integration efforts. IP companies can port and validate IP’s on architectures whose compatible software is available through the community.
