This paper describes the architecture and implementation of a high performance QR decomposition IEEE754 single precision floating point core, using a modified Gram-Schmidt algorithm. Using Intel's new floating point Arria 10 FPGAs, synthesis is used to generate column high functional units, giving O(n2) processing times. The modified Gram-Schmidt algorithm is expressed in a different order to combine...
This paper describes the implementation of a high throughput FFTs implemented on FPGAs, using a modified version of the Radix 2N architecture. The implementation uses a synthesis method which supports “super-sampling” to provide very high throughput. Special vector structures in the tools and hardware architecture are supported where complex vectors form the input on each clock cycle, and multiple...
Radar system has been using a hybrid of analog and digital beamforming. Sub-arrays of phase shifters in the analog domain are digitized at the sub-array outputs for further digital beamforming processing. Such system suffers from limited bandwidth and is unable to create more than one simultaneous beam. Digital time delay beamforming brings many benefits such as wide bandwidth pulse waveform and simultaneous...
