Discrete Cosine Transform (DCT) is the function which is used widely in many image and signal processing standard applications. High throughput with low power architecture is a major concern but there is a limitation in designing such architecture. When the architecture performs in high throughput rate at the operating time it will consume more power. Hence, high speed architecture with low power is utmost important. The One Dimensional (1-D) DCT can be obtained by prime-length DCT algorithm method.
