Automotive SoC semi-conductor industry is getting bigger with growth of demand of automotive infotainment. Especially, SoC platform includes CPU, DSP, CODEC and multiple operational units. In this paper, we propose a reconfigurable micro-controller platform to be able to use additional functions for other purpose. This design is dynamically reconfigurable in order to maximize utilization of Huffman Decoder and IMDCT block while minimizing dynamic power consumption and circuit size. When compared with a conventional design, the proposed design is 30% better in the number of used LUT4s, 10% better in terms of the number of used SLICE’s, 4% better in terms of SLICE Register, and 14% better in dynamic power consumption of a FPGA device.
