X4CP32 is a coarse-grained parallel/run-time reconfigurable microprocessor with 2 programming levels. As case study shows a pipelined parallel version to the 2D DCT. The RPU presents an average power consumption of 27,000 CGs per clock cycle. The performance of the 2D DCT version presented is 7.5 monocromatic 480x640 images per second. The X4CP32 consumes 397.870.921 CGs to perform the processing of the first 8x8 pixels input DCT matrix. This number decreases to 187.233.374 CGs when pipeline is full.
