Research Abstract
Reconfigurable DSP (RDSP)

PI: Nader Bagherzadeh

Funding: DARPA, NSF, CoRe/Broadcom

After the successful completion of the VLSI implementation and testing of our M1 chip that was based on the original Morpho architecture, the work has continued towards software development and architectural enhancements. The current work has resulted in developing efficient resource management algorithms for RDSP as well as extending the architecture to include new capabilities for computer graphics applications (e.g., ray tracing) as well as handling DVB-T (digital video broadcast DSP)baseband processing



Power Aware System Software and Algorithms

PI: Nader Bagherzadeh

Funding: DARPA

The power aware scheduling is an important component of many embedded systems such as mobile wireless systems and autonomous vehicles. All these systems have a common denominator: Power resources are limited and need to be spent efficiently and there are real-time tasks that need to be completed. My work in this area has resulted in a task scheduling software called IMPACCT that allows, in a user friendly manner, efficient scheduling of real-time tasks given the availability of a limited power resource. This approach for task scheduling is quite unique and has been proven successful when applied to the Mars Rover data obtained from NASA. If the IMPACCT tool was utilized for the Mars Rover mission, it would have reduced energy consumption by at least 20 percent, resulting in a longer mission on Mars. I have been working closely with Rockwell Collins to enhance and incorporate our tool for the next generation military radio systems called Joint Tactical Radio System (JTRS).
