D-Tunes: Configuration Engine For Geo-Replicated Cloud Storage, Jiawei Wang, Sanjay Rao

The Summer Undergraduate Research Fellowship (SURF) Symposium

When developing a web-based application, developers are facing stringent requirements to balance the latency, scalability and availability for their cloud database. Application developers need a specific replication configuration strategy based on the requirement of their application. To deal with this problem, some geo-replicated cloud strategy systems have emerged recently, like Cassandra. This project serves to design a web tool that can help configure the best replication strategies for geo-distributed data stores, which uses quorum-based protocols. Currently, our web tool D-Tunes, require a minimum input from users and generate specific scripts based on the inputs user provided. The program running these ...

Open Cortex-M0™ Modular Debug Unit, Chuan Yean Tan, Matthew Swabey

The Summer Undergraduate Research Fellowship (SURF) Symposium

The debug unit of a modern digital system on chip (SoC) is a critical unit that allows users to monitor and analyze the chip’s activity that occurs throughout a SoC design. Selection of the debug unit’s correct feature set and architecture are critical to the success of the design. Debugging systems that exist have different architectures and are closely coupled to their host SoCs. As a consequence they are resource intensive to improve on due to the different nature of each SoC designs. Moreover, the bus protocols that allow the debug unit to interact with the SoC design ...
