Abstract :
This paper explores the alternatives to a standard software implementation of DCT transformation algorithm, an IEEE standard 1180 definition, and compares the obtained results on FPGA development boards such as Spartan-3E and Virtex-5 with 32-bit MicroBlaze™ soft-core processor. Three cases of implementation are presented: a software implementation of AAN algorithm, a special FPGA ip-core that accelerates the standard DCT algorithm and a special FPGA ip-core that implements the AAN algorithm. Both of the ip-cores work as coprocessor to a standard MicroBlaze processor.
