We compare two parallel urray architectures for adaptive weight calculation based on QR-decomposition by Givens Rotations. We present FPGA implementations of borh orchitectures und compare them with un ASIC-bused solution. The throughput of the FPGA implementations is of the order 5-20 GigaFLOPS, making FPGA a viable alternative to ASIC implementation in applications where power consumption and volume cost ure not critical.
