The modified form is then output by the processing unit.
The proposed architecture is implemented on Xilinx Virtex-6 FPGA for any real matrices of size by dynamically inserting or removing the partial modules.
The evaluation results demonstrate a significant reduction in latency, area, and power as compared to other existing architectures.
The device according to any one of claims 6 and 7 wherein the processing elements comprise a plurality of general processing elements configured to perform multi- dimensional vector rotations as well as control, data movement functionalities, shift operations and add operations.9. Delosme • "Load balanced parallel QR decomposition on Shared Memory Multiprocessors," Parallel Computing, vol. The CORDIC modules were designed to approximately minimize gate count by performing CORDIC process iterations in each half of the clock cycle, however the Stage Controllers are designed to use full clock cycles for reduced complexity.
The device of claim 6 wherein the processing elements comprise a pipelined architecture including a plurality of processors disposed in series, the plurality of processors being 2D CORDIC processors, 3D Householder CORDIC processors, and 4D/2D configurable un-rolled CORDIC processors.10. In an embodiment, 2 sets of 2D CORDIC elementary rotation equations may be computed in the same single stage.
