Hardware/software systems must become easier and more fun to develop.  We aim to enable a more agile hardware development flow, to quickly and easily modify an existing design, letting us play with the resulting system.


Our People

Co-ordinated by our partner Jeff Parkhurst, Intel provides direct support for faculty and staff including Professors Mark Horowitz, Pat Hanrahan, Clark Barrett, Priyanka Raina, Kayvon Fatahalian, and Rick Bahr along with Dr. Stephen Richardson.

Open Source Pledge

Center researchers pledge to use and develop open-source hardware and software, and it is the intention of all Agile Hardware Center researchers that any hardware and software will be released under an open source model, such as the 3-clause BSD license.  The center is open to all Stanford faculty who share this goal.

AHA Agile Hardware Project

The three pillars of AHA funding

While advances in software tools and frameworks have enabled individuals to create interesting new products in reasonable time frames, hardware designs take large teams multiple years. This disparity in required effort decreases hardware innovation and interest.  To address this issue, we must make hardware/software systems easier and more fun to develop, which means that we need to enable a more “agile” hardware development flow, making it possible to quickly and easily modify an existing design and play with the resulting system. To foster this goal of agile hardware design, we initiated the AHA Agile Hardware Project, supported by three strong pillars of funding: ISTC Agile, Intel's Science and Technology Center (ISTC) for Agile HW Design; DARPA/NFS government agencies; and Stanford's own industrial affiliates program. Our research complements and coordinates with similar efforts from partners at UCB Aspire.

Tool Chain

To support agile practices, our research will create a new tool chain for design and testing of unified hardware/software systems optimized for rapid design iteration. We aim to create the right interfaces in the generated hardware and the tool chain to allow both to be leveraged in future hardware projects. A common theme underlying this project is taking modern software engineering ideas and applying them to hardware design.

Coarse Grain Reconfigurable SoC

To further simplify the hardware design process, we will create an SoC combining open source Linux with ARM cores and a CGRA optimized for image processing. Our tool chain will let designers seamlessly move from writing application code to running the application on the SoC. Accomplishing smooth cooperation between CPU and specialized hardware requires software connectors that first hook the hardware to the OS, and then join application software to the resulting OS ports, services and/or drivers.

Improved SMT Solvers

From high-level validation to optimization to layout, agility requires replacing manual efforts with efficient automated tools wherever possible.   Currently, SMT (satisfiability modulo theory) solvers are used in design automation for a wide range of tasks.  But their performance is often a bottleneck, and the applications frequently require optimization in addition to feasibility checking.  We aim to dramatically improve the performance of SMT solvers for hardware analysis and to add capabilities for optimization.
