[Mp4-tech] Which Codec implementation is better [ software ba sedorHardware Based ]

[Alan Thomson]

Hi Prashant - 
A fully hardware implementation will give you more performance - higher
speed or lower power consumption,
which may be important for battery-powered devices. It's also likely to give
a lower unit cost if you are
making lots of devices.
So it depends what your goals are.

what about the disadvantages of software based codec implementations and
other trade offs for hardware/chip based codec implementation

Hi Prashant, 
   Software based codec has following advantages, 
        i)  Code can be ported across many platforms without any change or
with minor modifications if required. It gives better re-usability and
time-to-market 
        ii) General DSP or RISC processor in a system, can be used for other
codecs (audio etc) also.         
        iii) Software updating will be easier than hardware modification.
 Please correct me if my understanding is wrong!

software based or Hardware Based ]	
Hello All 
  i am new to this digital content would , i would like to know and
understand the Pros/Cons of different methods of implementation of the MPEG
-4 , MPEG-2 decoder is better compared to the other . 
  Based on my current understanding there are two ways by which the MPEG-4
/MPEG-2 decoder's  can be implemented the first method is using a combo of
DSP processor and software implementation of MPEG-4/2 decoder whereas the
other is to implement the full hardware based MPEG-4/2 decoder ,   i think
it's always better to have 100% hardware based 
decoder from performance point of view , i dont know what are the advantages
of using a software based MPEG-4/2 decoder on the top of DSP processor
.......... 
i would be really grateful if  you guys can provide your opinions and imputs
in this regard 
warm regards, 
Prashant Desai
