Video algorithm (e.g. H.264, MPEG2/4 etc) requires tremendous amount of computation power and data bandwidth. This complexity depends on encoding vs. decoding mode, video standard, resolution, frame-rate and visual quality constraints. Many video architecture solutions typically use multiple processing elements (e.g. multiple DSPs or MCU, DSP/MCU with dedicated accelerators or FPGA etc) to achieve the high computation requirements for video algorithms. These architectures provide new challenges to video software's that are typically designed to run on a single processor. This paper presents software design for a video architecture using parallel processing elements. This paper explains following aspects in detail a) Software partitioning b) Algorithm specific optimizations c) Processor specific optimizations d) Efficient DMA/Cache usage e) Concurrent scheduling of all parallel processing elements. The given approach is explained with example of MPEG4 encoder on TMS320DM6446, which is Davinci TM family device from Texas Instruments Ltd. The given software architecture is scalable for various video standards (e.g. H.264, MPEG2/4 etc) as well as various parallel processing hardware solutions. The software achieves performance D1@30fsp on given device at less than 50% of DSP load.Index terms-architecture, video coding, parallel processing elements, MPEG4, H.264, Davinci TM .

Bangalore is the capital of Karnataka and is the fifth largest city in the country and it is growing at a higher rate than other cities in India. Due to Revolution in IT sector, so it attracts more migrants towards city, thus it requires developed roads, grade separators, subways, mass transit systems etc. In Bangalore city on an average, 2 major & 2 minor junctions exists for every kilometer of road length, Due to which increase in travel time, frequent bottlenecks and break downs occur and also delay and congestion beyond the traffic management control. Existing infrastructure of road networks in Bangalore is overcrowded and to ease traffic related problems, Since ORR (outer ring road) were constructed, but now traffic on ORR is reached the saturated level
