Graduate Student Researcher, 2005 – 2006.

ROCCC (RIVERSIDE OPTIMIZING COMPILER FOR CONFIGURABLE COMPUTING) support for partial reconfiguration on Virtex-4 FX FPGA. Automatic generation of dynamic co-processors for speeding up software tasks using optimized IP CORE libraries.

Graduate Student Researcher, 2003 – 2005.

RISE (Riverside Sensor) Project comprised of porting the TinyOS from the Atmel AVR architecture to the Chipcon CC1010 (8051). We have interfaced a storage board comprising of SD-CARD and NOR Flash memory on the SPI Bus of the RISE platform. Renesas-M16/C and ARM-7 based co-processing platform are utilized for frequency domain analysis of audio data. Development of a low power time synchronization mechanism based on the WWVB radio signal is underway. Our proposed Sense and Store paradigm which logs data onto low power flash memory built onto the sensor node and involves in-situ data processing has demonstrated typical energy savings of 70% on actual sensor platforms. We are also conducting active research on sensor lifetime maximization based on a given power envelope.

Research Intern, Summer 2005.

Hardware Assisted RTOS: System level conceptualization and implementation of Hardware assisted Real Time Operating system for Control Dominated Systems. The hardware RTOS includes acceleration for port based communication and shared memory access, and is designed on NEC’s BDL (Behavioral Description Language). The Software runs on an ARM926EJ-S processor that also includes a customized context switching kernel. The complete system is simulated in NEC’s cycle accurate Hardware-Software simulator viz. Classmate and the target application is H263 / MPEG 1 video encoder. Initial speedup gain is about 6.5x vis-à-vis the eCoS and POLIS approaches.

Automatic Softening of SoC Hardware: Development of a patentable idea which involves

(automatic migration of Hardware components to a V850 processor). A cost metric based on silicon gate count vs. performance of various hardware components of an SoC design is used to strategically soften lower performance, but high gate-count tasks from Hardware (ASIC) to Software (V850 processor). We have obtained a 30% gain in silicon floor area, while still meeting the performance requirements of the WEP / WPA encryption test bed.
