EXPERIENCE

Intern, Intel Corporation Summer 2012

Group: Server Development Group; Manager: Sailesh Kottapalli


Was part of an architecture team responsible for planning and designing communication components on a future Intel server product. The components were related to the power management unit, the random number generator and other uncore components. Tasks included communicating with other teams in order to assess all requirements and restrictions; creating high-level designs and specifications using Visio and Word; presenting this work to other teams for feedback and approval.

Exploiting 3-D IC for Energy Efficient Heterogeneous Processors


Lead architecture researcher charged with designing a heterogeneous processors that, when implemented using 3-D IC technology, delivers an improved performance/power spectrum over the 2-D version of the same design. Avenues of contributions includes: design and verification of cores using Verilog; researching 3D techniques using C++ and Verilog simulations (e.g., 3D fast thread migration, 3D resource sharing among cores on different tiers and exploiting on-chip DRAM); and the development of power modeling tool for different processor designs using Cacti and PrimeTime results from synthesizing a wide range of core designs. The project includes two fabrications – one 2D and one 3D.

FPGA Modeling of Diverse Superscalar Processors


Developed a tool to automatically construct, synthesize and simulate diverse superscalar processors on an FPGA. Performance, resources and complexity are managed using various FPGA-specific techniques (e.g., clock decoupling). The project included integrating 3rd-party IP such as DRAM, UART and SD Card controllers.

FabScalar


Contributed to FabScalar, a tool for generating RTL of out-of-order superscalar processors with different superscalar widths, depths and structure sizes. Major contributions include bug fixes, porting to MIPS ISA, updating the code to SystemVerilog and various frontend and backend design improvements.

C++ Processor Simulator Development


Updated an in-house C++ multi-core processor simulator to support the research group’s needs. Improvements include: porting the simulator from Alpha to the MIPS ISA, adding support for heterogeneous core types and thread migration, and developing new in-order and out-of-order core models.

Web Application Development


Conceptualized and developed a web application used to generate and view graphs comparing user-requested statistics of simulation runs. The application server stores and retrieves simulation results from a database and sends the user-requested data to the client, which generates and displays an interactive graph. Required the use and knowledge of Python, SQLite, HTML, Javascript/JQuery/AJAX and various popular web application frameworks.

Comprehensively and Dynamically Reconfigurable Superscalar Processor


Contributed to the initial concepts and designs of a dynamically reconfigurable superscalar processor. Each configuration mimics the frequency, performance and power of static designs while also dynamically adapting to changing workload behaviors.

Undergraduate Research Assistant, Southern Illinois University, Carbondale 2008 –2009

Advisor: Dr. Wei Zhang

Study on the Energy Efficiency of Just-in-time Compiler Optimizations


Researched the impact of dynamic compiler optimizations on the performance and energy consumption of mobile devices. Energy dissipation was modeled using Wattch models. This research was presented at the Argonne National Laboratory’s Symposium for Undergraduates in Science, Engineering and Mathematics (2008).
