The UltraLong FFT solution is ideal for applications where memory usage is a critical concern and FFT lengths surpass the internal memory capabilities of FPGAs or ASICs. This solution breaks down the FFT process, leveraging external memory for storage, allowing for efficient handling of larger data sets. Key features include data segmentation into manageable parts, rotation/twiddle stages to maintain performance, and multiple bank memory architectures for optimal throughput.\n\nDesigned to maximize continuous data processing, the UltraLong FFT uses external high-speed memory such as QDR SRAM and DDR SDRAM to meet extended length requirements. These configurations ensure that even with limited on-chip memory, performance potential is not capped. This approach not only simplifies the handling of extensive data but also aligns with today's demanding processing needs, providing a balanced solution for continuous, real-time applications.\n\nThe UltraLong FFT offers flexibility in its core design, accommodating varying lengths and processing speeds. It also supports fixed and floating-point operations, enabling precise customization to achieve high-speed data throughput. Such versatility ensures that it caters effectively to the needs of high-demand industries where processing efficiency and memory management are of utmost importance.
