“As an emerging computer scientist and an early-career computer architecture researcher, I am thrilled to be working on Micron’s new Automata Processor (AP). The opportunity to be the first to benchmark, evaluate and develop applications for an industry-new technology is extraordinary. I am drawn to the novelty of the AP’s unique MISD architecture. We have already successfully demonstrated performance superiority of this new processor for certain class of applications. I am very excited to continue my work exploring new capabilities for the AP.” – Jack Wadden, Graduate Research Assistant

CAP White Papers
Our group has demonstrated tremendous application potential using Micron’s Automata Processor. Below are some example application areas that may be of interest to industry partners and government sponsors. In addition to leading expertise on (and to date, exclusive access to) AP technology, our team also has extensive experience and expertise with hardware acceleration in general.
If you are a company or research lab, and are interested in exploring how the AP and other hardware acceleration technologies can be applied to meet your needs, please contact us and we will respond shortly; and if appropriate, we will be more than happy to develop a white paper to address your needs.
The AP’s massively parallel operation allows it to quickly check for prescribed patterns and their variations. This capability enables the AP to be uniquely suited for cybersecurity applications such as packet inspection and attribution. We believe there is a wide range of applications for AP technology in industry and national defense.
The advent of Big Data brought unprecedented opportunities but also significant analytics challenges. The AP’s ability to quickly implement association rule mining (ARM) algorithms such as frequent itemset, sequential pattern mining, and frequent subtree mining can quickly identify relations and patterns in massive datasets. We also believe tremendously valuable insight can also be gained from open internet sources such as social media platforms. However, the volume, variety, velocity, and veracity challenges of internet open source data is a formidable challenge. The AP’s ability to speedup implementation of entity resolution (ER) can be leveraged to perform attribution on internet open source data. ARM and ER are a few examples of how we think the AP can be effectively applied for data reduction.
Approximate string matching/ Bioinformatics
Aligning DNA reads to a reference genome is a common and time consuming process. We have demonstrated significant speedups implementing DNA alignment on the AP. Furthermore, the AP’s NFA flexibility allows it to be very effective at tolerating variations (gaps, mutation, and insertions) in candidate patterns. This is capability is analogous to approximate string matching. That is, the AP is able to effectively match string patterns with varied edit distance. We envision many relevant research and industry applications based on this powerful capability.
