Other topics include scheduling intervals for reconfigurable computing, simultaneous retiming and placement for pipelined netlists, optical flow calculations on FPGA and GPU architectures, and sparse matrix- vector multiplication
on a reconfigurable supercomputer.
Algorithm: Vector Multiplication
with a Generalized Tensor Product
On the other hand, the proposed stream acceleration approach directly updates the RC or BRC matrix structure, which allows for very efficient matrix vector multiplication
as well as GaussSeidel relaxation, and the approach is always faster than the SuiteSparse library.

In particular, this leads to a complexity of O(n) for the matrix vector multiplication
with diag [([G.
CPU: CPU time, MV: # of matrix/ vector multiplications

In this paper we study a different approach, based on divide-and conquer algorithm, for finding the inverse of matrices, the scalar and vector multiplications
are computed by floating point error free algorithms.
In the CGLS algorithm, vector multiplications
are required in Equations (12) and (14), which are Kp and [K.
This mainly requires only simple matrix vector multiplications
