摘 要：正Since DCT performs very close to the statistically optimal Karhunen-Loeve Transform（KLT）,it is widely used in digital signal processing,especially for speech and image data *** DCT algorithms and VLSI architectures for real-time computation capabilities are required *** is known that VLSI implementation of distributed arithmetic is very efficient for computing ***,an algorithm is presented to convert the DCT and inverse DCT（IDCT） to *** implementation of the algorithm has same advantage as any implementation using distributed arithmetic.
