The operation method of the proposed invention, there is no need for the Random Access Memory (RAM) to store the data; instead, shift registers with some multiplexers are enough to perform the memory operation with less hardware. There are three steps in the FFT computation such as input storage, data processing and output retrieval. The data processing step is further configured in four different operations. The number of operation mainly depends upon the size of the FFT, which is equal to log2N modes. During each operation, the DSRT changes its structure and these structures are basically MDC (Multi-path Delay Commutator) structures."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data scheduling register tree for radix-2 FFT architecture","description":"The present invention discloses a data scheduling register tree structure for radix-2 FFT architecture.
