Abstract
We present a prototype design of the MOLEN polymorphic
processor, a CCM based on the co-processor architectural
paradigm. The Xilinx Virtex II Pro technology is
used as a prototyping platform. Experimental results prove
the viability of the MOLEN concept. More precisely, the
MPEG-2 application is accelerated very closely to its theoretical
limits by implementing SAD, DCT and IDCT in
reconfigurable hardware. The MPEG-2 encoder overall
speedup is in the range between 2.80 and 2.96. The speedup
of the MPEG-2 decoder varies between 1.56 and 1.63.
