The matrix inversion architecture adapts the back substitution, Givens Generation (GG), Givens Rotation (GR), and the QRD 2D systolic array with the whole matrix inversion system. As previously developed by Reference [25], the target polytope model of QRD is represented as follows: 𝐀(ΠΣ)...
we take the 90 degree rotation from this: to this: Asshown herethe axis angle for this rotation is: heading = 0 degrees bank = 90 degrees attitude = 0 degrees so substituteing this in the above formula gives: ch=cos(heading) = 1 ...
