AVSynDEx: A Rapid Prototyping Process Dedicated to the Implementation of Digital Image Processing Applications on Multi-DSP and FPGA Architectures

Virginie Fresse, Olivier Déforges, Jean-François Nezan
2002 EURASIP Journal on Advances in Signal Processing  
We present AVSynDEx (concatenation of AVS + SynDEx), a rapid prototyping process aiming to the implementation of digital signal processing applications on mixed architectures (multi-DSP + FPGA).  ...  One main advantage is that only a signal processing designer is needed, all the other specialized manual tasks being transparent in this prototyping methodology, hereby reducing the implementation time  ...  An Mpeg-2 coder has already been developed and implemented on the multi-C4x-FPGA platform [24] .  ...

Video compression with parallel processing

Ishfaq Ahmad, Yong He, Ming L Liou
2002 Parallel Computing  
Designing efficient coding algorithms continues to be a prolific area of research.  ...  Since video compression is multi-step in nature using various algorithms, parallel processing can be exploited at an individual algorithm or at a complete system level.  ...  VLIW style has been introduced mainly into latest DSPs (for example, Trimedia TM-1 of Philips, TI C6X DSP and Chromatic Mpact) for multimedia and networking services.  ...
