[Mp4-tech] Which Codec implementation is better [ software based or Hardware Based ]

[Shanmugam T]

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!

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
