Title: Helen Hai-Jo Tarn: Innovator in Digital Signal Processing
Introduction
Helen Hai-Jo Tarn is a prominent inventor based in San Jose, CA (US). She has made significant contributions to the field of digital signal processing, holding 2 patents that showcase her innovative approach to technology.
Latest Patents
One of her latest patents is titled "Pipeline FFT architecture for a programmable device." This invention describes a pipeline Fast Fourier Transform (FFT) architecture designed for programmable devices. It includes a first Radix-2 butterfly stage that receives an input and provides an output while truncating at least one Least Significant Bit. Additionally, a delay and swap stage is involved, which processes the output further. The second Radix-2 butterfly stage then takes the output and another input to produce a third output, truncating at least one Most Significant Bit. Both butterfly stages are implemented in digital signal processing slices of a programmable device.
Another notable patent is "Memory segmentation for fast Fourier transform." This patent outlines various methods for performing a fast-Fourier transform (FFT) of N input data elements using a radix K decomposition. The approach involves writing input data elements to addressable memories and performing multiple passes on the data. Each pass includes reading, permuting, and calculating data elements in parallel, ultimately resulting in efficient data processing.
