• · Worked extensively on static timing analysis tool (encounter timing engine), wherein the engine attempts to statically (without simulation) verify the synchronization of clock and data signals for every flop in the design. This is important for the correct functioning of sequential logic designs. Major challenge in this product was increased complexity of chips and multi million gate SOC’s. These complexities demanded that the existing algorithms were enhanced to take care of new features required as well as improve on the execution efficiency.
• · Developed and maintained algorithm for clock path timing calculation with various design constraints from sdc files.
• · Worked on clock latency calculation performance improvements. The execution time was improved over 50% in 2 months
• Designed and maintained timing model extraction module. Extended timing model extraction module to produce accurate timing models for path based timing analysis.

• Worked on the OMAP family of SoC's (OMAP1510,OMAP1610,OMAP2420) as a OS porting and multimedia solutions engineer.
• Designed and implemented Media framework for these SOCs.
• Designed and implemented DMA and Interrupt framework inside Linux kernel.
• Ported u-boot bootloader on OMAP platforms
• Ported Linux kernel on OMAP platforms
• Designed and implemented Device drivers for Camera, Sound, Flash and other peripherals on OMAP SOCs.

• Worked on a Fingerprint Identification system for chipcard and security business unit, wherein a smart card could be authenticated using fingerprint identification. The smart card had to be made capable of capturing a fingerprint image and matching with the stored fingerprint on the smart card, thus avoiding any central storage of fingerprint data. Contributed towards optimization of fingerprint encoding with respect to program size and efficiency.
• The whole fingerprint identification system was restructured / ported from C++ to C and then ported onto a dual core embedded test chip (Unispeech) consisting of 8051 Micro controller and Oak DSP.
• Developed a C library which was used to replace the STL containers like linked list, doubly linked list, queue , stack and map.
• Designed a novel algorithm to perform fingerprint encoding on overlapping strips of fingerprint image. This was initially done so as to optimize on internal memory. Later the same algorithm was used for stripe fingerprint sensors.
