Abstract
A method and circuit computes a Discrete Cosine Transform in a more efficient manner for improving the computation speed, thereby reducing the computation time and allowing a higher number of digital samples to be processed. The circuit provides a microcontroller that includes a parallel accumulation multiplier for performing a first transform of the input data. A further quantization step is then performed on the transformed data. Likewise, the method includes the first transform being computed by the parallel accumulation multiplier. A further quantization step is performed on the transformed data. In this respect, the method and circuit provides good performance in terms of compression rate.
