Scalable linear array architectures for matrix inversion using Bi-z CORDIC
JW Luo, CC Jong - Microelectronics Journal, 2012 - Elsevier
In this paper, VLSI array architectures for matrix inversion are studied. A new binary-coded z-
path (Bi-z) CORDIC is developed and implemented to compute the operations required in
the matrix inversion using the Givens rotation (GR) based QR decomposition. The Bi-z
CORDIC allows both the GR vectoring and rotation mode, as well as division and
multiplication to be executed in a single unified processing element (PE). Hence, a 2D (2
dimensional) array consisting of PEs with different functionalities can be folded into a 1D …
