Technology is integrated into daily life more than before as it evolves through
communication area. In the past, it started with audio devices that help us to
communicate while far between two ends of communication line. Nowadays
visual communication comes in front considering the communication technology.
This became possible with the improvement in the compression techniques of
visual data and increasing speed, optimized architecture of the new family
processors. These type processors are named as Digital Signal Processors
(DSP&rsquo / s). Texas Instruments TMS320C6000 Digital Signal Processor family offers
one of the fastest DSP core in the market. TMS320C64x sub-family processors
are newly developed under the TMS320C6000 family to overcome disadvantages
of its predecessor family TMS320C62x. TMS320C64x family has optimized
architecture for packed data processing, improved data paths and functional units,improved memory architecture and increased speed. These capabilities make this
family of processors good candidate for real-time video processing applications.
Advantages of this core are used for implementing newly established H.264
Recommendation. Highly optimizing C Compiler of TMS320C64x enabled fast
running implementation of encoder blocks that bring heavy computational load to
encoder. Such as fast implementation of Motion Estimation, Transform, Entropy
Coding became possible. Simplified Densely Centered Uniform-P Search
algorithm is used for fast estimation of motion vectors. Time taking parts
enhanced to improve the performance of the encoder.
