Sparse and irregular sampling in array processing
2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2002Rule-based thinning and element placement methods are first discussed. This includes random arrays, binned random arrays, periodic thinning, element shadowing properties, and fractal arrays. The algorithmic optimization of layouts of 1-D and 2-D sparse arrays is presented and it is empirically derived that the peak sidelobe level for an array with K ...

Sparse Matrix Computations on Parallel Processor Arrays
SIAM Journal on Scientific Computing, 1993This paper deals with the balancing of distributed compressed storage of large sparse matrices on a massively parallel computer. The authors say that an assignment of matrix elements to the processor array preserves the integrity of the matrix if for every row(column) all its nonzero elements are placed into processors lying in a single row(column) of ...

APPLICATION OF ARRAY PROCESSOR TO SPARSE ELIMINATION
Proceedings of SPE Reservoir Simulation Symposium, 1979Abstract The Floating Point Systems array processor AP120B can be used to efficiently solve large systems of linear equations by a sparse Gaussian elimination technique. Bench mark tests show the following results: For LU factorization, the AP120B requires 22 to 35% less CPU time than the IBM 370/168; for forward or

Accessing Sparse Arrays in Parallel Memories
1983The concept of dense and sparse execution of arrays is introduced. Arrays, themselves, can be stored in a dense or sparse manner in a parallel memory with m memory modules. Hardware is proposed for speeding up the execution of array operations of the form C(c//0 plus cI) implied by A(a//0 plus al) OP B(b//0 plus bI), where a//0, a, b//0, b, c//0, c are
